Conditions Which Generate This Code:
Illustration 1 g01298952
Schematic of the position sensorThis diagnostic trouble code is associated with the position sensor. This diagnostic trouble code is recorded when the ECU reads the signal from the sensor as being shorted to the +battery. The sensor produces a PWM signal.Possible causes of the diagnostic trouble code is listed:
The supply circuit to the sensor is open.
The return circuit is open.
The signal circuit is shorted to the +battery.
The signal circuit is open or the sensor is disconnected.
The sensor has failed.
The ECU has failed. This is unlikely.Note: The following test procedure may create other diagnostic trouble codes. Ignore these created diagnostic trouble codes and clear the diagnostic trouble codes when the original diagnostic trouble code has been corrected. Ensure that the diagnostic trouble code of CID 1824 FMI 03 is active before performing this procedure.Note: Use a digital multimeter for the measurements in this procedure.Test Step 1. CHECK THE VOLTAGE AT THE SENSOR.
Turn the disconnect switch and the key start switch to the ON position.
Disconnect the sensor from the machine harness.
At the machine harness connector for the sensor, measure the voltage between contact A (wire 709-OR) and contact B (wire J765-BU).Expected Result:The voltage should measure approximately 8 DCV.Results:
OK - The voltage is approximately 8 DCV. Proceed to test step 4.
NOT OK - The voltage is not approximately 8 DCV. Repair: There is a problem with the machine harness or the ECU has failed. It is unlikely that the ECU has failed. Proceed to test step 2.Test Step 2. CHECK FOR AN OPEN IN THE SUPPLY CIRCUIT.
The key start switch and the disconnect switch remain in the ON position.
The sensor remains disconnected from the machine harness.
At the machine harness connector for the sensor, measure the voltage from contact A (wire 709-OR) to ground.Expected Result:The voltage should measure approximately 8 DCV.Results:
OK - The voltage measurement is approximately 8 DCV. Proceed to test step 3.
NOT OK - The voltage does not measure approximately 8 DCV.Repair: The supply circuit is not correct. Repair the circuit or replace the circuit.STOPTest Step 3. CHECK FOR AN OPEN IN THE RETURN CIRCUIT.
Turn the key start switch and the disconnect switch to the OFF position.
The sensor remains disconnected from the machine harness.
Disconnect the machine harness connector J1 from the ECU.
At the machine harness connector for the sensor, install a jumper wire from contact B (wire J765-BU) to ground.
At the machine harness connector for the ECU, measure the resistance from contact J2-22 (wire J765-BU) to ground.Expected Result:The resistance measurement should measure less than 5000 ohms.Results:
OK - The resistance measurement is less than 5000 ohms. The harness is correct.Repair: Check the circuit again. If the Caterpillar Electronic Technician (ET) is available, use the Cat ET service tool in order to perform a "Wiggle Test" on the machine wiring harness. The "Wiggle Test" can detect shorts and opens in the machine wiring harness that are momentary or intermittent. It is unlikely that the ECU has failed. Exit this procedure and perform this procedure again. If the
