ASCM

DTC C0696

Circuit/Description

The air suspension control module (ASCM) module provides power (a regulated 5 volts) to each of the position sensors. The ASCM module also monitors this voltage supply for a fault condition which prevents proper regulation.

DTC Descriptor

This diagnostic procedure supports the following DTC:
- DTC C0696: Position Sensor Overcurrent (5 volt supply).

This vehicle has DTCs which include DTC Symptoms. For more information on DTC Symptoms, refer to DTC Symptom Description.






Conditions for Running the DTC

The ignition is ON.

Conditions for Setting the DTC

- The position sensor supply voltage is outside the valid range of 4.855-5.25 volts.
- The fault is detected for 1 second or more during ignition cycles, or during the same ignition cycle after clearing the DTC with a scan tool.

Action Taken When the DTC Sets

- The ASCM module will set a current DTC.
- The SERVICE SUSPENSION SYS messages will be displayed.

Conditions for Clearing the MIL/DTC

- The scan tool can be used to clear the DTC.
- The DTC is saved as history when the ASCM module no longer sees a position sensor supply voltage outside the valid range of 4.855-5.25 volts. The DTC will clear if the fault does not return after 50 consecutive ignition cycles.

Diagnostic Aids

Refer to Testing for Intermittent Conditions and Poor Connections.

Test Description

The numbers below refer to the step numbers on the diagnostic table.

2. This step determines if the fault is due to a short to ground.
3. This step determines if the fault is due to a short to voltage.
4. This step tests for a short to ground in the position sensor supply circuits.
5. This step tests for a short between the position sensor supply and ground circuits.
6. This step tests for a short to voltage in the position sensor supply circuits.
