RETAINER 6G8803 - Caterpillar

This diagnostic code is associated with the articulate left solenoid. The FMI 13 diagnostic code is activated when the ECM detects that the solenoid needs calibration.The Implement ECM provides a PWM output signal to the solenoid in order to provide proportional control of the solenoid. The ECM will vary the electrical current of the PWM output signal based on the input command that is received from the articulation lever position sensor that is located in the left joystick assembly.Note: Before performing this procedure, verify that no other active CID 2171 diagnostic codes exist for the solenoid. If any other diagnostic codes are active for the solenoid, correct the problem before performing this procedure. Test Step 1. CALIBRATION
Perform the calibration procedure for the solenoid. Refer to Testing and Adjusting, "Calibration" section of this manual for the correct calibration procedure. Expected Result:The calibration procedure was performed successfully.Results:
YES. - The calibration procedure was performed successfully. Resume normal machine operation.STOP
NO. - The calibration was not successful.Repair: Repeat the calibration procedure for the solenoid. If the second calibration procedure is not successful, replace the solenoid. After solenoid replacement, refer to Testing and Adjusting, "Calibration" section of this manual for the correct calibration procedure. If the problem is still present after replacement and calibration of the new solenoid, the ECM may have failed.Prior to replacing an ECM, always contact your dealership's Technical Communicator for possible consultation with Caterpillar. This consultation may greatly reduce repair time. If the cause of the diagnostic code is not found, replace the ECM. Refer to Testing and Adjusting, "Electronic Control Module (ECM) - Replace".STOP
