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 less than 8.5 volts.
    • The transaxle input voltage is too low.
    • The engine speed is greater than 500 RPM.

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.
    • The power supply cut off to the pressure control solenoid (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.

Diagnostic Aids
    • Inspect the poor wiring harness connector for TCM connectors and transaxle wiring connectors.
    • Inspect the improperly formed or damaged terminals.
