Diagnostic Fault Information
Circuit/System Description
The Suspension Control Module adjusts the vehicle suspension ride height. The Suspension Control Module determines the height of the vehicle based on the voltage from the suspension position sensors.
Conditions for Running the DTC
The Suspension Control Module is powered up.
Conditions for Setting the DTC
The Suspension Control Module detects a short to ground or a short to battery at the right rear isolation valve circuit.
Action Taken When the DTC Sets
The Instrument Cluster displays the SERVICE SUSPENSION SYSTEM message.
Conditions for Clearing the DTC
The DTC will clear after the next malfunction free ignition cycle.
Diagnostic Aids
This circuit is monitored during every functional operation of the automatic leveling control.

Circuit/System Testing
1. Ignition OFF and all vehicle systems OFF. Disconnect the Q3RR Air Suspension Inlet Solenoid Valve - Right Rear. It may take up to 2 min for all vehicle systems to power down.
2. Test for less than 10 ohms between the low reference circuit terminal 37 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
3. Ignition ON.
4. Test for 4.8-5.2 V between the voltage circuit terminal 10 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
5. Replace the Q3RR Air Suspension Inlet Solenoid Valve - Right Rear.
