Connections of the J1939 CAN Data Link for the inclination sensor.The inclination sensor (blade angle sensor) communicates with the Implement ECM on the SAE J1939 CAN A data link system. The sensor provides the following machine condition status to the ECM:
pitch
roll
yaw
pitch rate
roll rate
yaw rateThe FMI 13 diagnostic code means the Implement ECM has determined that the Chassis Angle sensor (blade angle sensor) is out of calibration through the J1939 (CAN A) data link. The possible causes of the CID 1952 FMI 13 diagnostic code are listed below:
The machine serial number that is programmed in to the Caterpillar Monitoring System has changed since the last calibration.
The ECM has been replaced.
The ECM has failed. The failure of ECM is unlikely.Note: Ensure that the CID 1952 FMI 13 diagnostic code is active before performing this procedure.System Response:When this diagnostic code occurs, a warning (Category 1) is shown on the monitor. The diagnostic code causes the apron to default into a limited operation state. This state will not allow the machine to function at the maximum performance level.Test Step 1. Recalibrate The Chassis Angle SensorRecalibrate the position sensor. See Testing and Adjusting, "Machine Inclination Sensing Device - Calibrate".Expected Result:A successful calibration causes this diagnostic code to become inactive.Results:
YES - The calibration causes this diagnostic code to become inactive. Resume normal machine operation.STOP
NO - The calibration has not caused the diagnostic code to become inactive.Repair: With Caterpillar Electronic Technician (Cat® ET), if available, perform a "Wiggle Test" on the sensor circuit in the machine wiring harness. The wiggle test may detect momentary or intermittent shorts or opens in the machine wiring harness.If all possible causes of the problem have been investigated and no problem can be found, you may need to replace the inclination sensor.Prior to replacing the sensor, contact the Technical Communicator at your dealership for possible consultation with Caterpillar. This consultation may greatly reduce repair time and expense.STOP
