Rear Drive Clutch Control Solenoid Valve Control Circuit Open

Diagnostic Fault Information

Circuit/System Description

The rear differential clutch control module provides power and ground switching circuits to the rear drive clutch coil. The coil receives current from the rear differential clutch control module through PWM high side driver, and converts that signal into torque through the clutch to the rear tires when all wheel drive (AWD) is requested.

Conditions for Running the DTC

• The ignition is ON.
• Battery voltage is between 9-16 volts.

Conditions for Setting the DTC

• An open is detected on the high or low coil control circuits.
• A short to ground is detected on the high or low coil control circuits.
• A short to voltage is detected on the high coil control circuits.

Action Taken When the DTC Sets

One or more of the following actions may occur:

• All Wheel Drive Off or code 173 (AWD Disabled) will be displayed in the Driver Information Center.
• Service All Wheel Drive or code 73 (Service AWD) will be displayed in the Driver Information Center.

Conditions for Clearing the DTC

• The condition for the DTC is no longer present.
• The DTC is not detected in 40 consecutive drive cycles.

Circuit/System Testing

1. Ignition OFF and all vehicle systems OFF, disconnect the harness connector at the Q28 Rear Drive Clutch, ignition ON.
2. Test for 3-5 V between the control circuit terminal B and ground.

• If less than 3 V

1. Ignition OFF, disconnect the harness connector at the K47 Rear Differential Clutch Control Module.
2. Test for infinite resistance between the control 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 control circuit end to end.

• If 2 ohms or greater, repair the open/high resistance in the circuit.
• If less than 2 ohms, replace the K47 Rear Differential Clutch Control Module.

If greater than 5 V

1. Ignition OFF, disconnect the harness connector at the K47 Rear Differential Clutch Control Module, ignition ON.
2. Test for less than 1 V between the control circuit and ground.

• If 1 V or greater, repair the short to voltage on the circuit.
• If less than 1 V, replace the K47 Rear Differential Clutch Control Module.

If between 3-5 V

3. Test for less than 1 V between the control circuit terminal A and ground.

If 1 V of greater

1. Ignition OFF, disconnect the X2 harness connector at the K47 Rear Differential Clutch Control Module.
2. Test for less than 1 V between the control circuit and ground.

• If 1 V or greater, repair the short to voltage on the circuit.
• If less the 1 V, replace the K47 Rear Differential Clutch Control Module.

If less than 1 V

4. Ignition OFF, connect the harness connector at the Q28 Rear Drive Clutch. Disconnect the X2 harness connector at the K47 Rear Differential Clutch Control Module.
5. Test for infinite resistance between the control circuit terminal A and ground.

If less than infinite resistance

1. Ignition OFF, disconnect the harness connector at the Q28 Rear Drive Clutch.
2. Test for infinite resistance between the control circuit and ground.

• If less than infinite resistance, repair the short to ground on the circuit.
• If infinite resistance, replace the Q28 Rear Drive Clutch.

If infinite resistance

6. Test for 1.5-2.5 ohms between the control circuit terminal A and the control circuit terminal B.
7. Test for infinite resistance between the control circuit and ground.

If not between 1.5-2.5 ohms

1. Ignition OFF, disconnect the harness connector at the Q28 Rear Drive Clutch.
2. Test for less than 2 ohms between the K47 Rear Differential Clutch Control Module control circuit terminal A and the Q28 Rear Drive Clutch control circuit terminal A.

• If 2 ohms or greater, repair the open/high resistance on the circuit.
• If less than 2 ohms, test or replace the Q28 Rear Drive Clutch.

If between 1.5-2.5 ohms

8. Replace the K47 Rear Differential Clutch Control Module.

Component Testing

Static Test

1. Ignition OFF, disconnect the harness at the Q28 Rear Drive Clutch.
2. Test for 1.5-2.5 ohms between the control terminal B and the low reference terminal A.

If not between 1.5-2.5 ohms

Replace the Q28 Rear Drive Clutch.

If between 1.5-2.5 ohms

3. Test for infinite resistance between each terminal and the Q28 Rear Drive Clutch case.

If not infinite resistance

Replace the Q28 Rear Drive Clutch.

If infinite resistance

4. All OK.
