Limp-In Mode
PCM monitors transaxle for electrical or internal problems. If battery voltage is lost or PCM senses a transaxle failure and a DTC is set, PCM de-energizes the 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 is reduced.
When ignition is turned off and then back on again, PCM will reset for normal operation until it senses another failure. Transaxle will then reenter limp-in mode.
