Schematic of the suspension cylinder pressure sensors
This diagnostic code is associated with the left front suspension cylinder pressure sensor. This diagnostic code is recorded when the Payload Measurement Control (PMC) determines that the signal from the sensor is not valid and/or there is no output from the sensor. The possible causes of this diagnostic code are listed below:
The sensor has failed.
The signal wire is open.
The signal wire is shorted to ground.
The signal wire is shorted to other circuits in the machine harness.
The signal wire is shorted to the +battery circuit.
The Payload Measurement Control (PMC) has failed. This is unlikely.Use this procedure to troubleshoot the suspect performance of suspension cylinder pressure sensors or any failure that is associated with the suspension cylinder pressure sensors.Note: This test checks for sensor voltages at the sensor when all the circuits are connected. You should not disconnect any electrical connectors, unless you are directed to disconnect a connector in the procedure that is provided below. Troubleshoot the diagnostic code before disconnecting any circuits. Disconnecting the sensor from the harness before measuring the voltage may alter a poor connection. This will make the proof of cause difficult or impossible.Locate the suspect sensor. Identify the sensor wires and connector contacts. DO NOT DISCONNECT ANY HARNESS CONNECTORS AT THIS TIME. Turn the key start switch to the ON position. It is recommended that the engine be shut off, unless it is necessary for the engine to be running. The truck can be empty or the truck can be loaded.Test Step 1. CHECK THE SENSOR SUPPLY VOLTAGE.
At the sensor connector, identify the +V and ground circuits.
Insert the 7X-1710 Multimeter Probe leads into the back of the sensor's connector along side of the +V and the ground circuit wires.
Measure the system voltage. Expected Result:The voltage is between 22.0 DCV and 29.5 DCV.Results:
YES - The voltage is between 22.0 DCV and 29.5 DCV. The system voltage is present. proceed to test step 2.
NO - The voltage is less than 22.0 DCV. The circuit is not correct. Repair: Trace the +V and ground circuits in the machine harness. Repair the machine harness or replace the machine harness. If the machine harness has not failed the sensor is the cause of the failure. Replace the sensor. A failed sensor is unlikely.STOPTest Step 2. CHECK THE SENSOR SIGNAL VOLTAGE.
At the sensor connector, identify the signal and ground circuits.
Insert the 7X-1710 Multimeter Probe leads into the back of the sensor's connector along the side of the signal and ground circuit wires.
Measure the signal voltage. Expected Result: The signal voltage is between approximately 1.0 DCV and 5.0 DCV. Results:
The voltage is greater than 5.0 DCV - The signal voltage is not correct. Proceed to test step 3.
The voltage is less than 1.0 DCV. - The signal voltage is not correct. Proceed to test step 4.
The voltage is between 1.0 DCV and 5.0 DCV - The signal circuit is correct. Proceed to test step 5.Test Step 3. CHECK THE SIGNAL CIRCUIT FOR
