DTC Descriptor
DTC C0696 00
- Position Sensor Overcurrent
Diagnostic Fault Information
Circuit/System Description
The electronic suspension control (ESC) module provides a common regulated reference voltage of approximately 5 volts to all of the position sensors and the automatic level control (ALC) sensor. The ESC module monitors this power supply for a malfunction that could prevent it from correctly regulating the supply voltage.
Conditions for Running the DTC
* Battery voltage is between 9-16 volts
* Ignition is ON
Conditions for Setting the DTC
* The ESC module senses suspension position sensor or automatic level control (ALC) sensor supply voltage under 4.75 volts or over 5.25 volts.
* The condition is detected for 1 second in 4 consecutive ignition cycles.
Action Taken When the DTC Sets
* Commands speed dependent damping system and normal force signals to the default state.
* The ESC sends a message to the instrument panel cluster (IPC) to display SERVICE SUSPENSION SYSTEM message.
Conditions for Clearing the DTC
* A history DTC will clear after 100 consecutive ignition cycles if the condition for the malfunction is no longer present.
* The ESC module senses the correct sensor supply voltage.
* The IPC clearing DTC feature.

Circuit/System Verification
Ignition ON, observe the scan tool Position Sensor Data parameters. The readings should vary between 0.35-4.75 volts while the vehicle is jounced.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at all 4 suspension position sensors and the automatic level control (ALC) compressor.
2. Ignition ON, test for 4.75-5.25 volts between the 5 volt reference circuit terminal and ground at each sensor connector.
• If less than the specified range, test the 5 volt reference circuit for a short to ground or an open/high resistance. If all circuits test normal, replace the ESC module.
• If greater than the specified range, test the 5 volt reference circuit for a short to voltage. If the circuit tests normal, replace the ESC module.
3. Reinstall each connector, one at a time, while verifying for 4.75-5.25 volts between the 5 volt reference circuit terminal and ground of the last connector to be connected.
• If the voltage is out of the range when one of the 4 connectors are connected, test or replace the suspect suspension component.
4. Replace the last remaining suspect suspension component.

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 Diagnostic Trouble Code (DTC) List - Vehicle Diagnostic Trouble Code (DTC) List - Vehicle and perform the appropriate diagnostic procedure.
