Chrysler 300: that needs to go through a drive cycle because we

This answer was rated:

I have a Chrysler(NNN) NNN-NNNNthat needs to go through a drive cycle because we just changed the battery. Where can I find the directions for this?

rmldaytona :

Hello. Which engine is in this vehicle?

Customer:

good question. off hand i don't know I'll have to look

rmldaytona :

If you do not know, then the 8th digit of the VIN will do. Infact, the complete VIN will be even better.

Customer:

i have the original sticker 2006 chrysler 300 touring v-6 3.5L

All Monitor Drive Trace



Pre-Conditioning Requirements:


- MIL must be off


- Cold start (Note: cold start temperature is undefined)


Driving Procedure


1) Warm engine up for five minutes (must reach closed loop)


2) Drive (with steady throttle) at a speed between 40 and 60 mph for 8 minutes.


3) Stop and idle for 3 minutes.


4) Drive (with steady throttle) at a speed above 20 mph for 2 minutes.


5) Turn key off, leave off for ten minutes (to run O2 sensor heater monitor).


Note: Due to the limited preconditions provided with this drive trace, NCVECS recommends using the monitor


specific drive traces for Chrysler vehicles.



Catalyst Monitor Drive Trace



Pre-Conditioning Requirements:


- MIL must be off.


- No DTCs present.


- Fuel level is between 15% and 85% full.


- ECT above 70º F.


- Engine must have run at least 90 seconds


- Engine between 1,350 & 1,900 rpm.


Driving Procedure


1) Idle vehicle for five minutes (to reach closed loop operation).


2) Drive with a steady vehicle speed between 30 and 45 mph for 2 minutes.



EGR System Monitor Drive Trace - Vacuum controlled



Pre-Conditioning Requirements:


- MIL must be off.


Driving Procedure


1) Idle vehicle for five minutes (to reach closed loop operation).


2) Drive with a steady vehicle speed between 40 & 60 mph for 8 minutes.



EGR System Monitor Drive Trace - Electronic



Pre-Conditioning Requirements:


- MIL must be off.


- MAP must be between 0-60 KPa.


- Engine speed between 500-850 rpm.


- ECT is above 180º F (90º C).


- No misfire temporary (pending) or matured fault present.


- A/C clutch, PS Switch and Cooling fans do not change state (turn off).


Driving Procedure


1) Idle vehicle for five (5) minutes (to reach closed loop operation).


2) Drive with a steady vehicle speed between 40 & 60 mph for 2 minutes.


3) Idle vehicle for three (3) minutes.


Note: This monitor evaluates EGR flow based on a change of engine roughness (idle stability).


Conditions causing un-stable idle will prevent this monitor from running.



Evaporative System Monitor Drive Trace



Trace 1: Standard Type

- No Evaporative DTCs present.


- Fuel level is between 30 & 85 % full.


Driving Procedure


1) Cold soak vehicle, start and idle vehicle for 4 minutes.


2) Drive in-town (stop and go) for 5 minutes, using smooth accelerations and decelerations.


3) Stop and idle vehicle for 4 minutes.



O2 Sensor Monitor Drive Trace



Pre-Conditioning Requirements:


- MIL must be off.


Driving Procedure


1) Idle vehicle for five minutes (to reach closed loop operation).


2) Drive with a steady vehicle speed above 25 mph for 2 minutes.

2) Shut engine off and leave vehicle off for ten minutes


Customer:

what does MIL stand for?

rmldaytona :

Malfunction Indicator Lamp. The check engine light, service engine soon light. Also called check your wallet light (not really)

Customer:

ok LOL

rmldaytona :

Glad you found that funny

rmldaytona :

What else may I help you with?

Customer:

the first one listed "All Monitor Drive Trace" does that mean it will reset everything with this one procedure?

rmldaytona :

There are 2 types of monitors (tests) a computer performs to test or fail a component. If a component fails, then the MIL illuminates.

Customer:

then i would have to do each test separately correct?

rmldaytona :

The first type is the continuous monitors which are also called the Drive Trace monitors. These are monitored by the computer at all times by measuring resistance for circuit integrity, voltage for proper signal ranges, and amperage for sticking switches, solenoids, heater elements.

rmldaytona :

The other monitors are drive cycle monitors which are tested only under certain conditions. Fuel level, outside temperature, engine temperature, engine speed, acceleration, deacceleration, engine running time...

Customer:

so in other words i have to do each test

rmldaytona :

Correct. But some tests overlap and if you read over the drive cycle requirements you will notice that some components are tested under other component's drive cycle requirements.

rmldaytona :

The hardest monitors to complete are the Evaporative and Catalyst.

Customer:

under trace 2 for evaporative it states cold soak vehicle????

rmldaytona :

Vehicle engine is completely cold. This basically ensures the Evaporative charcoal canister has fuel vapors stored.

rmldaytona :

Chrysler's Evaporative monitors are so difficult to complete that most scan tools have a function that runs the monitor in the bay and shows pass or fail. Takes about 10 minutes with a factory compatible scan tool.

rmldaytona :

What are the reasons for you to run the drive cycles anyways?

Customer:

we bought a new battery and the car failed the emissions test

rmldaytona :

How long do you have before you need to be retested?

Customer:

sept 30

rmldaytona :

If you drive the vehicle normally all monitors will be completed by then. In fact, all it takes is 2 to 5 days of normal driving to complete all the monitors. You were failed because some monitors showed incomplete right?

Customer:

right

rmldaytona :

Drive the vehicle for a few days normally and your monitors will run. Next time you install a battery, have a shop do it. We have a way of keeping power to the computers when the battery is disconnected so this exact problem does not happen. This is even more crucial on newer vehicles as sometimes a simple battery disconnect calls for resetting many components using a scan tool before the vehicle will even run, idle and shift correctly.

Customer:

ok thanks

rmldaytona :

You are welcome. Anything else I can help you with?

Customer:

no that solves my problem thank you

rmldaytona :

You are welcome.
