DTC Descriptor

DTC C0696
- Position Sensor Status

Circuit/System Description

The electronic suspension control module provides a common regulated reference voltage of approximately 5 V to all of the position sensors. The Suspension Control 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 3.75 V or over 5.625 V.

* 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 Suspension Control Module sends a message to the instrument panel cluster to display SERVICE RIDE CONTROL message.

Conditions for Clearing the DTC

* A history DTC will clear after 40 consecutive ignition cycles if the condition for the malfunction is no longer present.

* The Suspension Control Module senses the correct sensor supply voltage.

Circuit/System Verification

Ignition ON, observe the scan tool Position Sensor Data parameters while the vehicle is jounced. The readings should vary between 0.35-4.75 V.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at all suspension position sensors.

2. Ignition ON, test for 4.8-5.2 V between the 5 V reference circuit terminal A and ground at each sensor.

• If less than the specified range, test the 5 V reference circuit for a short to ground or an open/high resistance. If all circuits test normal, replace the K19 Suspension Control Module.

• If greater than the specified range, test the 5 V reference circuit for a short to voltage. If the circuit tests normal, replace the K19 Suspension Control Module.

3. Test for less than 0.35 V between the signal circuit terminal B and ground.

• If greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the K19 Suspension Control Module.

4. Reinstall each sensor one at a time. Test for 4.8-5.2 V between the 5 V reference circuit terminal A and ground of the last sensor connector to be connected.

• If not within the specified range when one of the 3 sensors are connected, test or replace the suspect suspension position sensor.

5. Test or replace the last remaining suspect suspension position sensor.

Component Testing

1. disconnect the harness connector at the affected suspension position sensor

2. Install a 3 A fused jumper wire between the 5 V reference terminal A and 5 volts. Install a jumper wire between the low reference terminal C and ground.

3. 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 V without any spikes or dropouts.

• If not within the specified range or if it is erratic, replace the applicable suspension position sensor.
