Limp-In Mode

TCM monitors transaxle for electrical or internal problems. If battery voltage is lost, or TCM senses a transaxle failure and a DTC is set, TCM de-energizes transmission control relay which then de-energizes solenoid assembly. Transaxle then enters limp-in mode. In limp-in mode, only Park, Neutral, Reverse and 2nd gear functions. Transaxle will not upshift or downshift. Vehicle can be operated, but performance will be reduced.

When ignition is turned off and then back on again, TCM will reset for normal operation until it senses another failure.
