DTC Descriptor

DTC C0696

Position Sensor Over current (5-volt supply)

Diagnostic Fault Information

Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. Initial Inspection and Diagnostic Overview

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

1. Ignition OFF, disconnect the harness connector at the suspension position sensor.
2. 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.

3. 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.

4. 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.

5. If all circuits test normal, test or replace the suspension position sensor.
