BRACKET 9J6912 - Caterpillar

This diagnostic code is associated with the Rotary Lift (Linkage) Position Sensor. The position sensor provides a PWM input signal to the Implement ECM. The FMI 13 diagnostic code is activated when the ECM detects a sensor that needs calibration.The sensor is a PWM sensor that operates at a frequency of approximately 500 100 Hz. The sensor provides a PWM duty cycle signal that will indicate the position of the lift arms to the Implement ECM.Test Step 1. CALIBRATION
Perform the calibration procedure using the Monitoring System Display or Using Cat ET. Expected Result:The calibration procedure was performed successfully.Results:
OK - The calibration procedure was performed successfully. Resume normal machine operationSTOP
NOT OK - The calibration was not successful.Repair: Repeat the calibration procedure for the sensor.If the second calibration procedure is not successful, replace the rotary lift position sensor.After replacement of the sensor, the sensor must be calibrated. Perform the calibration procedure for the new sensor. If the problem is still present after replacement and calibration of the new sensor, the ECM may have failed.Prior to replacing an ECM, always contact the Technical Communicator at your dealership for possible consultation with Caterpillar. This consultation may effect repair time. If the cause of the diagnostic code is not found, replace the ECM. Refer to the Testing and Adjusting, "Electronic Control Module (ECM) - Replace" section in this manual for additional information.STOP
