DTC Descriptor

DTC C0696 00
- Position Sensor 5V Supply

Circuit/System Description

The Suspension Control Module provides a common regulated reference voltage of approximately 5 volts to all of the suspension 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 Suspension Control 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 Suspension Control Module sends a message to the Instrument Cluster 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 Suspension Control Module senses the correct sensor supply voltage.

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 the parameter is not between 0.35-4.75 V
Refer to Circuit/System Testing

• If the parameter is between 0.35-4.75 V

3. All OK.

Circuit/System Testing

1. Ignition OFF, all vehicle systems OFF. Disconnect the harness connector at all B152 Suspension Position Sensors. It may take up to 2 min for all vehicle systems to power down.

2. Test for 4.8-5.2 V between the 5 V reference circuit terminal 3 and ground of each B152 Suspension Position Sensor.

• 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 5 V reference 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 5 V 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 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 5 V reference 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

3. Connect each harness connector one at a time.

4. Verify with a scan tool that the voltage stays between 4.8-5.2 V between the 5 V reference circuit terminal and ground for each connector to be connected.

• If the voltages is not between 4.8-5.2 V
Replace the appropriate Q152 Suspension Position Sensor.

• If the voltage stays between 4.8-5.2 V

5. All OK.
