Theory Of Operation

WARNING: This page is about a different car, the 2010 Dodge Avenger and 2010 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.

After the controller is reset (ignition on from an off position), the microprocessor checks the integrity of each memory (RAM) location by writing to it and reading back from it. The read value should be the same as the written value. If the memory integrity check fails the MIL will illuminate after 10 seconds of vehicle operation and transmission will be placed in limp-in.
