The service engine light means that the computer has monitored a malfunction in the engine emmission control circuit.There will be a code stored in the computer to isolate the circuit or sensor at issue.The code must be retieved using a code reader or scan tool.Many parts stores pull codes for free.Get the codes and post back with them for further help with the light, unless they help you out when the codes are retrieved.The security light issue requires the use of a DRBII scan tool at the dealer to adress any concerns with it.It may just require a Passkey relearn procedure which is very common.Not sure what they are charging these days for this.It may even still be under warranty.The same goes for the Service engine light.Federal law requires manufacturers to warranty many major and minor parts of the emmission control system.The info is in the back of your owner manual or in the seperate warranty booklet.This is a federally mandated warranty which has nothing to do with the standard warranty.I will post the law on it for you to copy.It may come in handy later if someone tries to pull the wool over your eyes.It's good AMMO to have when emmission related repairs are required.Heres the law:

EMISSIONS WARRANTIESFOR 1995 AND NEWER CARS & TRUCKS
Federally required emission control warranties protect you, thevehicle owner, from the cost of repairs for certain emission relatedfailures that result from manufacturer defects in materials andworkmanship or that cause your vehicle to exceed federal emissionstandards. Manufacturers have been required by federal law to provideemission control coverage for vehicles since 1972. There are twofederal emission control warranties discussed in this fact sheet: (A)"Performance Warranty" and (B) "Design and Defect Warranty". Thisfact sheet explains each warranty in detail, provides you with a listof some of the parts covered under these warranties, explains theprocedures for making an emissions warranty claim, and answers some ofthe most commonly asked questions about emissions warranties.Finally, we will give you some tips on how to prevent futureemission-related failures and maintain the longevity of your vehicle'sengine.
A. PERFORMANCE WARRANTY
The Performance Warranty covers repairs which are required duringthe first 2 years or 24,000 miles of vehicle use because the vehiclefailed an emission test. Specified major emission control componentsare covered for the first 8 years or 80,000 miles. If you are aresident of an area with an Inspection and Maintenance (I/M) programthat meets federal guidelines, you are eligible for this warrantyprotection provided that:
* Your car or light-duty truck fails an approved emissions test;and
* Your vehicle is less than 2 years old and has less than 24,000miles (up to 8 years/80,000 miles for certain components); and
* Your state or local government requires that you repair thevehicle; and
* The test failure does not result from misuse of the vehicle or afailure to follow the manufacturers' written maintenanceinstructions; and
* You present the vehicle to a warranty-authorized manufacturerrepresentative, along with evidence of the emission test failure,during the warranty period.
During the first 2 years/24,000 miles, the Performance Warrantycovers any repair or adjustment which is necessary to make yourvehicle pass an approved, locally-required emission test and as longas your vehicle has not exceeded the warranty time or mileagelimitations and has been properly maintained according to themanufacturer's specifications.
B. DESIGN AND DEFECT WARRANTY
The Design and Defect Warranty covers repair of emission relatedparts which become defective during the warranty period. The Designand Defect warranty for model year 1995 and newer light-duty cars andtrucks is outlined below:
Design and Defect Warranty Coverage for 1995 and newer light-dutyvehicles:
* Emission control and emission related parts are covered for thefirst 2 years or 24,000 miles of vehicle use; and
* Specified major emission control components are covered for thefirst 8 years or 80,000 miles of vehicle use.
According to federal law, an emission control or emission relatedpart, or a specified major emission control component, that failsbecause of a defect in materials or workmanship, must be repaired orreplaced by the vehicle manufacturer free of charge as long as thevehicle has not exceeded the warranty time or mileage limitations forthe failed part.
Design and Defect Warranty coverage may vary depending on thetype of vehicle you have (e.g., heavy-duty trucks, motorcycles orrecreational vehicles have different time and mileage requirements).To determine the length of warranty coverage that applies to yourvehicle, look for the emissions warranty information in your owner'smanual or warranty booklet. If you own a California vehicle, you maybe entitled to additional warranty coverage.
The owner's manual or warranty booklet will also provide you withguidance on the procedures for obtaining warranty coverage. If youhave questions about the emissions warranties on your vehicle or needhelp in filing a warranty claim, contact your local car dealer or themanufacturer's zone or regional representative listed in your owner'smanual or warranty booklet.
What Emission Control and Emission Related Parts Are Covered by TheDesign and Defect Warranty?
An emission control part is any part installed with the primarypurpose of controlling emissions. An emission related part is anypart that has an effect on emissions. Listed below are some examplesof parts or systems which fall under these definitions. A morecomplete list can be found in your owner's manual/warranty booklet.If any of the parts listed below fail to function or functionimproperly because of a defect in materials or workmanship, causingyour vehicle to exceed federal emission standards, they should berepaired or replaced under the emissions warranty if your vehicle isless than 2 years old and has been driven less than 24,000 miles. Onemanufacturer may use more parts than another, so the following list isnot complete for all vehicles.
EMISSION CONTROL PARTS
Exhaust Gas Conversion Systems

hoses, gaskets, brackets, clamps and other accessories used in theabove systems
EMISSION RELATED PARTS
These are examples of other parts of your vehicle which have aprimary purpose other than emissions control but which neverthelesshave significant effects on your vehicle's emissions. If any of theseparts fail to function or function improperly, your vehicle'semissions may exceed federal standards. Therefore, when any of theparts of the following systems are defective in materials orworkmanship and have failed in a way that would be likely to causeyour vehicle's emissions to exceed federal standards, they should berepaired or replaced under the emissions warranty:
Fuel Injection System
turbocharger intake manifold
distributor spark plugsignition wires and coil
hoses, gaskets, brackets, clamps, and other accessories used inthe above systems.
What Are Specified Major Emission Control Components?
There are three specified major emission control components,covered for the first 8 years or 80,000 miles of vehicle use on 1995and newer vehicles:
* Catalytic converters.
* The electronic emissions control unit or computer (ECU).
* The onboard emissions diagnostic device or computer (OBD).
Catalytic converters are critical emission control componentsthat have been installed on most cars and trucks manufactured since1975. Since engines don't burn fuel completely during the combustionprocess, the exhaust contains a significant amount of harmfulpollutants such as carbon monoxide, hydrocarbons, and oxides ofnitrogen. The catalytic converter aids the conversion of thesepollutants to less harmful substances such as carbon dioxide, watervapor, nitrogen, and oxygen before the exhaust is expelled into theenvironment.
The electronic emissions control unit or computer monitorscertain powertrain functions and controls various operating parametersto help the vehicle run efficiently and with the lowest possibleemissions. Ignition, transmission function, air injection, exhaustgas recirculation (EGR), engine operating temperature and fuel systemparameters are some of the systems monitored and/or controlled by theelectronic emissions control unit.
The onboard emissions diagnostic device monitors the operation ofa vehicle's emission control system and alerts the driver with adashboard light when malfunctions occur. The system will record wherethe problem is occurring and assist automotive technicians indiagnosing and repairing emission control malfunctions. Since someemission control malfunctions do not have an adverse effect on vehicleperformance, they can go undetected by the driver for quite some time.The onboard diagnostic device will help catch malfunctions early,preventing a significant output of harmful exhaust emissions from yourvehicle, and possibly in time to be covered by the emissions controlwarranty. Often this "device" is part of the electronic control unitmentioned above.
In the future, there may be other parts or components thatqualify for this coverage. Check your owner's manual or warranty bookfor possible additional coverage.
How Long Do the Emissions Warranties Apply to Individual Parts of MyVehicle?
For 1995 and newer model year vehicles, emission control andemission related parts are warranted for the first 2 years or 24,000miles of vehicle use. Specified major emission-control components arewarranted for the first 8 years or 80,000 miles of vehicle use.
Parts with a stated replacement interval, such as, "replace at15,000 miles or 12 months," are warranted up to the first replacementpoint only.
How Do I Know Whether I Am Entitled to Coverage Under the EmissionsWarranties?
If you or a qualified automotive technician can show that anemission control or emission related component, or a specified major,emission-control component, is defective, the repair or replacement ofthe part is probably covered under the Design and Defect warranty. Ifyour vehicle failed a federally approved emissions test and has notexceeded the time and mileage limitations for the Performancewarranty, any repairs or adjustments necessary for your vehicle topass should be covered by the manufacturer if the failure was notcaused by improper maintenance or abuse. When you believe you haveidentified a defective part, or your vehicle fails an emission test,you should follow the procedures for making a warranty claim asidentified by the manufacturer in your owner's manual or warrantybooklet. When taking your vehicle in to have repairs performed underthe Performance Warranty, be sure to have with you a copy of the I/Mtest report as proof of your emissions test failure.
May I Have My Regular Repair Facility Perform Warranty Repairs?
If you plan to have the manufacturer pay for a repair undereither of the emissions warranties, you must take the vehicle to afacility authorized by the vehicle manufacturer for repair to givethem the opportunity to diagnose and repair it. Note that if yourregular repair facility is not authorized by the vehicle manufacturer,they are not obligated to advise you of parts that are covered underwarranty. Before giving your automotive technician the "go ahead" toperform repairs, check your owner's manual/warranty booklet forpossible warranty coverage.
Do the Emissions Warranties Apply to Used Vehicles?
Yes. It does not matter if you bought your vehicle new or usedfrom a dealer or anyone else. As long as the vehicle has not exceededthe warranty time or mileage limitations, these warranties apply.
IMPORTANT NOTE: Before buying a used vehicle, be sure that all ofthe emission control components as originally installed by themanufacturer are present and functioning properly. If emissioncontrol components are missing or have been tampered with, or theconfiguration of the exhaust system has been changed, the emissionswarranties on this vehicle may be void. In addition, if you live inan area with an I/M program, the vehicle will probably not passinspection and you will incur the expense of parts or repairsnecessary for the vehicle to pass.
Can Any Portion of An Emissions Warranty Repair Be Charged to Me?
If you have valid warranty claim, you cannot be charged for anycosts associated with the diagnosis or repair of the problem,including labor charges, parts, or miscellaneous items that arenecessary to complete the repair. For example, if a manufactureragrees to replace a catalytic converter under the emissions warranty,you should not be charged for the diagnosis of the bad converter, orany pipes, brackets, adjustments, or labor needed to complete thereplacement.
What Reasons Can the Manufacturer Use to Deny a Warranty Claim?
If your vehicle is within the age and mileage limits for theapplicable emissions warranty, the manufacturer can only deny coverageif evidence shows that you have failed to properly maintain and useyour vehicle, causing the part or emission test failure. Someexamples of misuse and malmaintenance include the following:
* vehicle abuse such as off-road driving or overloading; or
* tampering with emission control parts or systems, includingremoval or intentional damage of such parts or systems; or
* improper maintenance, including failure to follow maintenanceschedules and instructions specified by manufacturer, or use ofreplacement parts which are not equivalent to the originallyinstalled parts.
What Should I Do If My First Attempt to Obtain Warranty Coverage IsDenied?
If your first attempt to receive emissions warranty coverage isdenied, you should do the following:
1) Ask for a detailed explanation, in writing as to why emissionswarranty coverage was denied; and
2) Ask for the name(s) of the person(s) involved in the decisionto deny coverage, including anyone from the manufacturer'sregional or zone office; and
3) Ask for the name(s) of the person(s) with the manufacturer youshould contact to appeal the denial of coverage under theemissions warranty.
4) Contact and, if necessary, write to the person mentioned aboverequesting coverage and giving the basis for your request. Repeatand continue the appeal process until you are satisfied or haveexhausted all means of appeal.
What If the Dealer Claims That My Vehicle Can Pass the I/M TestWithout Repair?
The law does not require that you fail every I/M test in order totrigger the warranty. If a valid test shows that you have an emissionproblem or there is a defective part, you should get it fixed, whileyour vehicle is still within the warranty period. Otherwise, youmight fail a future test because of the same problem and have to payfor the repair yourself. If you doubt your original test results orthe dealer's results or diagnosis, you can always get another opinionfrom another dealer or your I/M program.
How Can Maintenance Affect My Emission Warranty Coverage?
Performance and the cost of scheduled maintenance are yourresponsibility. You may either perform scheduled maintenance yourselfor have a qualified repair facility perform it for you.
If a part fails as a direct result of your vehicle not beingproperly maintained or being used in a manner inconsistent with themanufacturer's recommendations, or a part fails as a result of thevehicle being involved in an accident, the manufacturer may not berequired to repair or replace the failed part under warranty. Forexample, failure to replace the spark plugs at the intervals specifiedin the maintenance schedule can lead to misfiring and eventual damageto your catalytic converter - a very expensive part to replace. Ifthe maintenance is not performed properly as recommended, themanufacturer may deny warranty coverage.
To ensure maximum air pollution reduction from the emissioncontrol system, as well as to ensure continued warranty coverage,better gas mileage and performance, and longer vehicle life, youshould have all maintenance performed as recommended by themanufacturer's schedule. A list of scheduled maintenance for yourvehicle can be found in the owner's manual or warranty booklet.
Do I Have to Show Any Maintenance Receipts Before I Can Make anEmissions Warranty Claim?
No. Proof of maintenance is not required in order to obtaincoverage under the emissions warranty if an emission control oremission related component, or a specified major emission controlcomponent, is found to be defective in materials or workmanship.However, when it is likely that the lack of proper maintenance hascaused the particular part to fail, you may be asked to show thatscheduled maintenance was performed.
If you perform scheduled maintenance yourself, you should keep adetailed log of work performed and any receipts for parts purchased toperform the maintenance. In some instances, you may be asked toqualify your ability to perform such maintenance. Vehicles shouldalways be maintained according to manufacturers' specifications.
Are Dealers the Only Persons Allowed to Perform Scheduled MaintenanceRecommended by the Manufacturer?
No. Scheduled maintenance may be performed by anyone who has theknowledge and ability to perform the maintenance and repair. You mayeven maintain the vehicle yourself, as long as the maintenance isperformed according to the manufacturer's instructions provided withthe vehicle.
For your protection, before taking your vehicle to a repairfacility to have any maintenance performed, check your maintenancebooklet and make a list of the scheduled maintenance to be performedat that time. We suggest that you present this list to your autotechnician as opposed to merely asking for a "tune-up" or a "12,000miles servicing." Your receipt should list all the maintenanceperformed and should be kept for your records.
If you maintain the vehicle yourself, you should keep receiptsfor parts and a maintenance log to verify your work.
If I Need Replacement Parts, Must I Use the Vehicle Manufacturer'sParts Only?
No. A manufacturer cannot require the use of any specific brandof parts in the maintenance of your vehicle. However, themanufacturer can require you to use parts that are of equal quality tothe original parts.
If I Buy a Used Vehicle, How Do I Know Whether It Has Been MaintainedAccording to The Maintenance Schedule?
The best way to learn whether the vehicle has been maintainedaccording to its schedule is to ask the seller for receipts provingthat all of the scheduled maintenance was performed. Having thereceipts on hand will provide necessary evidence if the question ofmaintenance arises when considering repairs under warranty. Toprevent any loss of your vehicle's emission performance, you shouldcontinue to follow the maintenance schedule in the owner's manual orwarranty booklet.
If the seller does not have the owner's manual, warranty bookletor maintenance schedule, you can obtain them from the manufacturer.
How Will I Know If My Claim Has Been Accepted As Valid?
After you present your vehicle for a Performance Warranty claim,the manufacturer has 30 days to either repair the vehicle or notifyyou in writing that the claim has been denied. If you are making aPerformance Warranty claim and your I/M program imposes a shorterrepair deadline, the manufacturer must meet the deadline. Because ofthe significance of these deadlines, you should get writtenverification from the dealer showing that they acknowledge the date bywhich repairs must be made.
There are no specific requirements for Defect Warranty claims,however, manufacturer responses should be made within a reasonabletime period.
What Happens If the Manufacturer Does Not Respond to My PerformanceWarranty Claim Within the 30-Day Deadline?
You may agree to extend the deadline, or it will be automaticallyextended if the delay was beyond the control of the manufacturer.Otherwise, a missed deadline means the manufacturer forfeits the rightto deny the claim. You may then have the repair performed at afacility of your choice, at the manufacturer's expense. (Thisrequirement only applies to Performance Warranty claims.)
What Do I Do If the Manufacturer Will Not Honor What I Believe to Be aValid Emissions Warranty Claim?
If you believe the manufacturer has not honored a valid claim andyour vehicle has not exceeded the time and mileage limitations, youshould contact an authorized warranty representative and follow theprocedures outlined in your owner's manual or warranty booklet. If theauthorized dealer denies your warranty claim, contact themanufacturer's regional or zone office for further assistance. If youare still not satisfied, follow the appeals procedure outlined in yourmanual or warranty booklet.
Of course, you are entitled to pursue any independent legalactions you consider appropriate to obtain coverage under theemissions warranties. In addition, the Environmental ProtectionAgency (EPA) is authorized to investigate the failure of manufacturersto comply with the terms of these warranties. If you have followedthe manufacturer's procedures (including those for appeals) for makinga warranty claim as set out in your owner's manual or warrantybooklet, have received a written denial and you are not satisfied withthe manufacturer's determination, you may submit a letter to EPA atthe following address. It should provide details of the situationincluding the basis for the claim, a copy of the written denial,copies of your letters to the manufacturers, and copies of anyreceipts for emission control parts and repairs you have paid for:
U.S. Environmental Protection Agency Vehicle Programs & Compliance Division (6405J) Attn: Warranty Complaints 401 M Street, SWWashington, DC 20460
Other sources of assistance may be your local or State consumerprotection agency or office of the Attorney General. You also shouldbe aware that low-cost or free legal assistance may be availablethrough a local legal aid office, the State bar association, or a lawschool clinic staffed by law students.
If an emission control or emission related part, or a specifiedmajor emission control component is defective, or if your vehiclefails an I/M test, and your vehicle is within the time and mileagelimitations for emissions warranty coverage:
* Present a warranty claim to an authorized warranty representative.
If your warranty claim is denied:
* Ask for the reason for denial, in writing.
* Follow the appeal procedures in your owner's manual.
If you are not satisfied with the manufacturer's decision:
* Contact the EPA, which will investigate the denial of avalid emissions warranty complaint.
