94-95 Model

This Diagnostic Trouble Code (DTC) flashes the "CHECK TRANS" Indicator and sets the Backup Mode.




Circuit Description
- The Force Motor Solenoid is a device used to regulate Transmission line pressure. The Transmission Control Module (TCM) uses Throttle Position Sensor (TPS) information and Vehicle speed information to determine the line pressure appropriate for a given load. The TCM will regulate the pressure by applying a varying amperage to the force motor Solenoid. The applied amperage can vary from 0.1 to 1.1 amp. The TCM then monitors the amperage at the return line. If the return amperage is more than 0.2 amp from the commanded amperage, the DTC is stored.
- The line pressure can vary from less than 50 psi to more than 200 psi. The line pressure varies inversely to the amount of current. High current causes low pressure and low current causes high pressure.

Diagnostic Aids
- This diagnostic is an electrical test done by the TCM.

- Detection Conditions:
- The TCM monitors the amperage at the return line. When the return amperage is more than 0.2 amp from the commanded amperage, the DTC is stored.

- Action After The Detection Time:
- Backup Mode.

- Recovery Conditions:
- To recover do an Ignition Cycle.
