C0396 2016 Chevrolet Silverado Code - Range Actuator Position Sensor Circuit
Quick Answer
The Transfer Case Control Module receives input from the range actuator position sensor and the transfer case range position sensor. Common causes include Faulty Transfer Case Motor (Transfer Case Two/Four Wheel Drive Actuator), Transfer Case Motor harness is open or shorted, Transfer Case Motor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code C0396 2016 Chevrolet Silverado Description
The range actuator position sensor receives an 8-volt reference signal from the Transfer Case Control Module. In return, the range actuator position sensor sends the Transfer Case Control Module a variable pulse width modulated signal indicating the position of the transfer case and a range actuator position direction signal. The range actuator position sensor, inside the A16 transfer case motor, also known as the transfer case range actuator, works in conjunction with the range position sensor to confirm the transfer case position. The range actuator position sensor is more sensitive than the transfer case range position sensor and is able to indicate to the Transfer Case Control Module the exact position of the transfer case between range changes. It is also able to show how much clutch activation is being commanded at any time.
The transfer case range position sensor, also known as the transfer case two/four-wheel drive actuator position sensor, receives a 5-volt reference signal from the Transfer Case Control Module and sends back a continuously variable pulse width modulated signal to the Transfer Case Control Module. This continuously variable signal indicates the position of the transfer case actuator.
The range actuator position sensor is more sensitive than the transfer case range position sensor but needs to reference the transfer case range position sensor value at ignition ON and mode changes. The transfer case range position sensor is an absolute sensor. The Transfer Case Control Module synchronizes the range actuator position sensor with the transfer case range position sensor at ignition ON and mode changes.
The range actuator position sensor is an integral part of the A16 Transfer Case Motor and cannot be replaced independently.
The transfer case range position sensor, also known as the gear position sensor, is an independently replaceable part.
What are the Possible Causes of the DTC C0396 2016 Chevrolet Silverado?
- Faulty Transfer Case Motor (Transfer Case Two/Four Wheel Drive Actuator)
- Transfer Case Motor harness is open or shorted
- Transfer Case Motor circuit poor electrical connection
- Faulty Transfer Case Control Module
How to Fix the DTC C0396 2016 Chevrolet Silverado?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

Frequently Asked Questions about C0396 2016 Chevrolet Silverado Code
1. What does the OBDII code C0396 mean on a 2016 Chevrolet Silverado?
C0396 refers to a fault in the Range Actuator Position Sensor Circuit, which monitors the position of the transfer case range actuator.
2. What are the common symptoms of code C0396?
Symptoms include the “Service 4WD†message on the dashboard, inability to switch between 4WD modes, or unusual noises from the transfer case.
3. What causes the C0396 code to appear?
Common causes include a faulty range actuator position sensor, wiring issues like shorts or open circuits, or a malfunctioning transfer case control module (TCCM).
4. How can I fix the C0396 code on my Silverado?
Inspect the range actuator position sensor and its wiring for damage or corrosion. Replace the sensor if faulty, or repair any damaged wiring. If the issue persists, check the TCCM.
5. Can I still drive my 2016 Chevrolet Silverado with the C0396 code?
While the truck may still be drivable, 4WD functionality might be limited or unavailable, which could be problematic in off-road or poor weather conditions.
6. How do I diagnose the C0396 code?
Use a scan tool to confirm the code and inspect the transfer case range actuator sensor readings. Visually inspect the sensor, wiring, and connectors for damage or corrosion.
7. How much does it cost to repair the C0396 code?
Repair costs can vary. Replacing the range actuator position sensor typically costs $100-$300, while addressing wiring issues or replacing the TCCM may cost more.
8. Can a faulty TCCM cause the C0396 code?
Yes, a malfunctioning Transfer Case Control Module can cause improper communication with the range actuator position sensor, triggering the code.
9. Will clearing the C0396 code fix the problem?
Clearing the code without addressing the root cause will not fix the problem. The code will likely return if the underlying issue is not resolved.
10. Is the range actuator position sensor difficult to replace?
Replacing the sensor can be moderately challenging, as it is located on the transfer case. It may require tools and mechanical knowledge to access and replace.
