C0631

DTC C0631

CIRCUIT DESCRIPTION
The Air Suspension Sensor provides a signal voltage between 0.3 and 4.7 volts to the Air Suspension Module. This signal voltage represents the wheel's position relative to the body. The Air Suspension Module provides a 5 volt reference and a low reference to the sensor.

CONDITIONS FOR RUNNING THE DTC
At power-up and continuous when ignition is activate.

CONDITIONS FOR SETTING THE DTC
Air Suspension Module senses a suspension sensor voltage below 0.3 volts or above 4.7 volts.

ACTION TAKEN WHEN THE DTC SETS
- Air Suspension functionality is suspended.
- SERVICE AIR SUSPENSION message is displayed.

CONDITIONS FOR CLEARING THE DTC
The DTC will clear when the condition for setting the DTC is removed.


DIAGNOSTIC AIDS
This DTC is set for a high or low signal to the Air Suspension Module from the Air Suspension Sensor-RR.

TEST DESCRIPTION

Steps 1 - 7:

Steps 8 - 15:

The numbers below refer to the step numbers on the diagnostic table.
2. Checks the Air Suspension Sensor-RR data parameter.
3. Tests for the proper operation of the circuit in the high voltage range.
4. Tests for the proper operation of the circuit in the low voltage range. If the fuse in the jumper opens upon performing this test, the signal circuit has a short to voltage.
5. Tests for a short to ground in the 5 volt reference circuit.
7. Test the 5 volt reference circuit for the Air Suspension Sensor-RR.
