4WD/AWD Rear Differential Unit Actuator A

Where it lives

For C0095, the description names the actuator as the part involved.

Check these first

• An open or short in the rear differential actuator A circuit
• A failed rear differential actuator A motor
• Corrosion in the actuator connector
• A fault in the 4WD control module output

What to do next

1. Inspect the actuator A connector for corrosion and pushed pins
2. Check the actuator circuit for an open or short to ground
3. Measure the actuator motor resistance against a known-good value
4. Command the rear differential actuator with a scan tool and listen for it to move
5. Replace the actuator if the circuit tests good
6. Clear the code and retest
