Circuit Description

The transaxle control module (TCM) is an electronic device which monitors inputs to control various transaxle function including shift quality and transaxle sensors, switches, and components to process for use within its control program. Based on this input information, the TCM controls various transaxle output functions and devices.

Conditions for Setting the DTC
    • The system voltage is greater than 16 volts.
    • The transaxle input voltage is too high.

Action Taken When the DTC Sets
    • The malfunction indicator lamp (MIL) will illuminate.
    • The TCM will record operating conditions at the time that the diagnostic fails. This information will be stored in the Failure Records buffer.
    • Adopt Emergency/Substitute mode and constant 4th gear by hydraulic control.
    • After ignition OFF/ON: 3rd gear by hydraulic control. Possible P, R, and N also possible.
    • Power supply cut off to the PCS valve.

Conditions for Clearing the MIL/DTC
    • A MIL will turn OFF when the malfunction has not occurred after 3 ignition cycles.
    • A history DTC will clear after 40 consecutive warm-up cycles without a fault.
    • Using a scan tool can clear history DTCs.
