O-RING 0993057 - Caterpillar

Which Generate This Code:This diagnostic code is associated with the winch control handle position sensor. This diagnostic code is recorded when the ECM detects that the signal from the sensor is out of calibration.Note: In order to correct this diagnostic code, calibrate the sensor.Test Step 1. CALIBRATION
Perform the calibration procedure for the sensor. Use the Cat ET service tool in order to calibrate the sensor.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 sensor. Use the Cat ET service tool in order to calibrate the sensor.If the second calibration procedure does not correct the problem, replace the handle and sensor assembly. After replacement, calibrate the sensor.If the problem has not been corrected after the calibration of the new handle and sensor, the ECM may be faulty.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. See Troubleshooting, "Electronic Control Module (ECM) - Replace".STOP
