Diagnostic Instructions

* Perform the Diagnostic System Check - Vehicle (Diagnostic System Check - Vehicle) prior to using this diagnostic procedure.
* Review Strategy Based Diagnosis (Strategy Based Diagnosis) for an overview of the diagnostic approach.
* Diagnostic Procedure Instructions (Diagnostic Procedure Instructions)provides an overview of each diagnostic category.

DTC Descriptor
DTC C0696 00
- Position Sensor Overcurrent

Circuit Description

The automatic level control (ALC) adjusts the vehicle suspension ride height. The automatic level control (ALC) module determines the height of the vehicle based on the signal from the rear height sensor which is supplied a 5-volt reference voltage from the module. The module raises and lowers the vehicle in order to keep the vehicle level.

Conditions for Running the DTC

Battery voltage is between 9-16 volts.

Conditions for Setting the DTC

The module detects the position sensor 5-volt reference circuit is less than 4.75 volts or greater than 5.25 volts.

Action Taken When the DTC Sets

The ALC system will be inoperative.

Conditions for Clearing the MIL/DTC

* When the fault is no longer present, DTC C0696 will change from a current DTC to a history DTC on the next ignition cycle.
* DTC C0696 will be cleared from history after 50 ignition cycles.

Circuit/System Verification

Verify that DTC C0696 is not set.

If the DTC is set, perform the Suspension Position Calibration (Service and Repair) procedure. If the DTC resets replace the ALC sensor/module.

Repair Verification

1. Install any components or connectors that have been removed or replaced during diagnosis.
2. Perform any adjustment, programming or setup procedures that are required when a component or module is removed or replaced.
3. Clear the DTCs.
4. Use the scan tool Diagnostic Counter Reset output control function to bypass the 3 consecutive ignition cycle requirement for setting a DTC. This will ensure that if a DTC was to be reset during the repair verification process, it will be displayed on the scan tool.
5. Turn OFF the ignition for 60 seconds.
6. Turn ON the ignition.
7. If the repair was related to a DTC, duplicate the Conditions for Running the DTC and use the Freeze Frame/Failure Records, if applicable, in order to verify the DTC does not reset. If the DTC resets or another DTC is present, refer to the and perform the appropriate diagnostic procedure.
