94-95 Model

This Diagnostic Trouble Code (DTC) does not flash the "CHECK TRANS" Indicator and does not set the Backup Mode.




Circuit Description
- When the driver presses the Accelerator Pedal down fully, the Kick Down Switch closes, sending a ground signal to the Transmission Control Module (TCM).
- This information is used to do shifts with a high Engine speed rpm.
- When the Kick Down Switch is closed the Throttle Position Sensor (TPS) is already at 100%.

Diagnostic Aids
- This diagnostic is not an electrical test done by the TCM but a test between different information ("logic test").

- Detection Conditions:
a. Kick Down Switch "ON" (short to ground) and TPS less than 70%.
b. No malfunction: TPS short to voltage or ground (DTC 21 and DTC 22).
c. The conditions need to be present for at least 1 second.

- Action After The Detection Time:
- Kick Down information not taken into account.

- Recovery Conditions:
- To recover, Kick Down needs to be seen as "OFF" during detection time.
