This diagnostic code is recorded when the ECM determines that the torque converter lockup solenoid requires calibration. This diagnostic code will clear once the calibration procedure has been performed successfully. The diagnostic code will no longer be present.
Test Step 1. PERFORM CALIBRATION
- Use the Caterpillar Electronic Technician (ET) to perform the calibration procedure for the torque converter lockup solenoid.
Expected Result:
The calibration procedure was performed successfully.
Results:
- YES - The calibration procedure was performed successfully. Resume normal machine operation.STOP
- NO - The calibration procedure was not performed successfully.
Repair: Perform the calibration procedure again. If the calibration procedure does not correct the problem, ensure that the related hydraulic and mechanical components are operating correctly. If the hydraulic and mechanical components are operating correctly, there may be a problem in the wiring harness or in the solenoid. Refer to the other troubleshooting procedures for the solenoid in order to troubleshoot the circuit.
