Diagnostic Instructions
DTC Descriptor
DTC C0696: Position Sensor Over current (5-volt supply)
Circuit/System Description
The electronic suspension control (ESC) module provides a 5-volt reference to all 4 position sensors. The module monitors the voltage to ensure it is regulated between 3.7-5.5 volts.
Conditions for Running the DTC
The ignition is ON.
Conditions for Setting the DTC
The ESC module senses the position sensor 5-volt reference is below 3.7 volts or greater than 5.5 volts.
Action Taken When the DTC Sets
| • | Defaults to a normal damping force state. |
| • | The DIC displays SERVICE SUSPENSION SYSTEM message after 3 consecutive ignition cycles. |
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 5-volt reference is between 3.7-5.5 volts. |
Diagnostic Aids
If any position sensor supply circuit is shorted to ground, the scan tool will indicate all of the position sensor voltage readings as zero.

Circuit/System Verification
Ignition On, observe the scan tool position sensor voltage. The reading should be between 0.35-4.75 volts and change when the suspension position changes.
Circuit/System Testing
- Ignition OFF, disconnect the harness connector at the suspension position sensor.
- Ignition OFF, test for less than 1 ohm of resistance between the low reference circuit terminal C and ground.
| ⇒ | If greater than 1 ohm, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the ESC module. |
- Ignition ON, test for 3.7-5.5 volts between the 5-volt reference circuit terminal A and ground.
| ⇒ | If less than 3.7 volts, test the 5-volt reference circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the ESC module. |
| ⇒ | If greater than 5.5 volts, test the
5-volt reference circuit for a short to voltage. If the circuit tests normal, replace the ESC module. |
- Install a 3-amp fused jumper wire at the signal circuit terminal B. Toggle the jumper wire between the low reference circuit terminal C and the 5-volt reference circuit terminal A. Verify the scan tool position sensor voltage
parameter toggles between 0.35-4.75 volts.
| ⇒ | If the position sensor voltage does not toggle between the min and max values test the signal circuit for a short to voltage, short to ground or an open/high resistance. If the circuit tests normal, replace the ESC module. |
- If all circuits test normal, test or replace the suspension position sensor.
Repair Instructions
Repair Verification
- Install any components or connectors that have been removed or replaced during diagnosis.
- Perform any adjustment, programming or setup procedures that are required when a component or module is removed or replaced.
- Clear the DTCs.
- 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.
- Turn OFF the ignition for 60 seconds.
- Turn ON the ignition.
- 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
and perform the appropriate diagnostic procedure
