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.

Diagnostic Aids

This DTC is applicable for all suspension position sensors, so all of them need to be diagnosed.

Circuit/System Verification

1. Ignition ON.

2. Verify the scan tool Position Sensor Data parameters vary between 0.35-4.75 V while the vehicle is jounced.

• If not within 0.35-4.75 V
Refer to Circuit/System Testing

• If within 0.35-4.75 V

3. All OK.

Circuit/System Testing

1. Ignition OFF and all vehicle systems OFF. It may take up to 2 min for all vehicle systems to power down.

2. Disconnect the harness connector at the affected B152 Suspension Position Sensor.

3. Test for less than 10 ohms between the low reference circuit terminal C and ground.

• If 10 ohms or greater

1. Ignition OFF, disconnect the harness connector at the K19 Suspension Control Module.

2. Test for less than 2 ohms in the low reference circuit end to end.

• If 2 ohms or greater, repair the open/high resistance in the circuit.

• If less than 2 ohms, replace the K19 Suspension Control Module.

• If less than 10 ohms

4. Ignition ON.

5. Test for 4.8-5.2 V between the voltage circuit terminal A and ground.

• If less than 4.8 V

1. Ignition OFF, disconnect the harness connector at the K19 Suspension Control Module.

2. Test for infinite resistance between the voltage circuit and ground.

• If less than infinite resistance, repair the short to ground on the circuit.

• If infinite resistance

3. Test for less than 2 ohms in the voltage circuit end to end.

• If 2 ohms or greater, repair the open/high resistance in the circuit.

• If less than 2 ohms, replace the K19 Suspension Control Module.

• If greater than 5.2 V

1. Ignition OFF, disconnect the harness connector at the K19 Suspension Control Module, ignition ON.

2. Test for less than 1 V between the voltage circuit and ground.

• If 1 V or greater, repair the short to voltage on the circuit.

• If less than 1 V, replace the K19 Suspension Control Module.

• If within 4.8-5.2 V

6. Verify the scan tool Position Sensor parameter is less than 0.3 V

• If 0.3 V or greater

1. Ignition OFF, disconnect the harness connector at the K19 Suspension Control Module, ignition ON.

2. Test for less than 1 V between the signal circuit terminal B and ground.

• If 1 V or greater, repair the short to voltage on the circuit.

• If less than 1 V, replace the K19 Suspension Control Module

• If less than 0.3 V

7. Install a 3 A fused jumper wire between the signal circuit terminal B and the voltage circuit terminal A.

8. Verify the scan tool Position Sensor parameter is greater than 4.7 V.

• If less than 4.7 V

1. Ignition OFF, disconnect the harness connector at the K19 Suspension Control Module.

2. Test for infinite resistance between the signal circuit terminal B and ground.

• If less than infinite resistance, repair the short to ground on the circuit.

• If infinite resistance

3. Test for less than 2 ohms in the signal circuit end to end.

• If 2 ohms or greater, repair the open/high resistance in the circuit.

• If less than 2 ohms, replace the K19 Suspension Control Module.

• If greater than 4.7 V

9. Replace the B152 Suspension Position Sensor.
