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.
