Description:

This diagnostic trouble code is generated when the PTA control software detects that the transmission enable signal from the transmission enable relay does not correspond to the position of the reverse drive lever, which is transmitted by the TIA control software.

Reaction:

Limited or no function of the transmission until the error is corrected, indicating a critical issue with the transmission enable signal.

Recommendations:

Verify Transmission Enable Relay:

• Check the transmission enable relay for proper operation.
• Replace the relay if it is found to be faulty.

Inspect Reverse Drive Lever Sensor:

• Verify that the sensor for the reverse drive lever is functioning correctly.
• Replace the sensor if it is providing inaccurate position signals.

Check Wiring and Connectors:

• Inspect all wiring and connectors associated with the transmission enable relay and reverse drive lever sensor for signs of damage or disconnection.
• Repair or replace any damaged components.

Ensure CAN Bus Communication:

• Verify that the CAN bus is accurately transmitting the position of the reverse drive lever.
• Ensure there are no faults or interruptions in the CAN bus communication.

Note:

Maintaining accurate transmission enable signals is crucial for proper transmission operation. Regular checks and maintenance of relays and sensors can help prevent signal discrepancies and ensure smooth vehicle performance.
