CONTROL GP-HANDLE 2494746 - Caterpillar

TYPE="A" START="2">
Connect a voltmeter between pin A and pin B on the sensor side of the connector for the suspect sensor.
Measure the voltage between pin A and pin B for the suspect sensor(s).
Wiggle the harness while you monitor the voltage on the voltmeter. Perform the 45 N (10 lb) pull test on each wire in the circuit. Each terminal and each connector should easily withstand 45 N (10 lb) of tension and each wire should remain in the connector body. This test checks whether the wire was properly crimped in the terminal and whether the terminal was properly inserted into the connector.Expected Result:The supply voltage is approximately 5.0 0.2 VDC.Results:
OK - The supply voltage is approximately 5.0 0.2 VDC. An active -3 diagnostic code is present. Proceed to Test Step 3.
OK - The supply voltage is approximately 5.0 0.2 VDC. An active -4 diagnostic code is present. Proceed to Test Step 5.
Not OK - The supply voltage is not approximately 5.0 0.2 VDC. Proceed to Test Step 7.Test Step 3. Check for Battery Voltage on the Signal Wire
Measure the voltage on the harness side of the sensor connector between pin B and pin C for the suspect sensor(s).Expected Result:The signal voltage is less than battery voltage.Results:
OK - The signal voltage is less than battery voltage. Proceed to Test Step 4.
Not OK - The signal voltage is equal to battery voltage.Repair: There is a short in the harness to the battery. Repair the wiring.STOPTest Step 4. Create a Short at the Sensor Connector
Turn the keyswitch to the OFF position.
Disconnect the suspect sensor.
Use a wire jumper in order to create a short between terminal C (signal) and terminal B (sensor return) at the sensor connector.
Turn the keyswitch to the ON position.
