MID 039 - Machine Control Module CID 0839 - Right Front Strut Pressure Sensor FMI 04 - Voltage Below Normal
Illustration 1 g06042410
Mini schematic of the right front strut pressure sensor circuit
This diagnostic code indicates the Input/Output Module (I/O Module) detects the Right Front Strut Pressure Sensor voltage is below normal.The output frequency of the sensor changes as the pressure in the suspension cylinder changes. The sensor is powered by the machine electrical system.Note: This test checks for sensor voltages at the sensor when all the circuits are connected. Unless directed otherwise, do not disconnect any components. Troubleshoot the circuit "as is" before disconnecting any components.Note: Use a calibrated digital Multimeter for this procedure.Test Step 1. CHECK THE SENSOR SUPPLY VOLTAGE
Locate the suspect sensor.
Identify the sensor wires and connector contacts.Note: Do NOT disconnect any harness connectors.
Turn ON the keyswitch.Note: The truck can be empty or the truck can be loaded
At the sensor connector, identify the +V and ground circuits
Insert 7X-1710 Multimeter Probe leads beside the +V and ground circuit wires in the back of the connector for the sensor.
Measure the voltage.Expected Result:The voltage is between 22.0 DCV and 29.5 DCV.Results:
