DTC Descriptor
DTC C0696
- 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. 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 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 parameter. The reading should be between 4.75-5.25 volts.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connectors at all suspension position sensors.
2. Ignition ON, test for 4.75-5.25 volts between the 5-volt reference circuit terminal A 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 sensor, one at a time, while verifying for 4.75-5.25 volts between the 5-volt reference circuit terminal A and ground of the last sensor connector to be connected.
• If the voltage is out of the range when one of the sensors are connected, test or replace the suspect suspension position sensor.
4. Replace the last remaining suspect suspension position sensor.
Component Testing
1. Install a 3A fused jumper wire between the 5-volt reference terminal A and a external 5-volt power source. Install a jumper wire between the low reference terminal C and ground.
2. Sweep the suspension position sensor through the entire range while monitoring the voltage between the signal terminal B and the low reference terminal C. The range should vary between 0.35-4.75 volts without any spikes or dropouts.
• If not within the specified range or if it is erratic, replace the applicable suspension position sensor.
