SENSOR AS-MAG 5099822 - Caterpillar

Which Generate This Code:Note: The ECM switch supply provides power to the switch. The switch does not connect directly to the frame ground. The switch connects to the return circuit of the ECM. The ECM internally connects the return wire to frame ground.This diagnostic code is recorded when the ECM detects the signal of the switch as being out of calibration.In order to correct this diagnostic code, calibrate the switch. Perform the calibration procedure for the switch. See Testing and Adjusting, "Calibration" for more information.System Response:The diagnostic code of CID 2531 FMI 13 will be logged in the internal memory of the ECM. A level 1 warning will be generated.Test Step 1. CALIBRATION
Perform the calibration procedure for the switch.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 switch. See Testing and Adjusting, "Calibration" for more information.STOP
