C0396 2014 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 2014 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 2014 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

Frequently Asked Questions about C0396 2014 Chevrolet Silverado Code
1. What does the OBDII code C0396 mean on a 2014 Chevrolet Silverado?
The C0396 code indicates an issue with the Range Actuator Position Sensor Circuit, which is responsible for monitoring the transfer case range actuator's position in the 4WD system.
2. What are the common symptoms of code C0396 in a 2014 Chevrolet Silverado?
Symptoms may include the "Service 4WD" message on the dashboard, inability to engage or switch 4WD modes, and occasional drivetrain noises.
3. What causes the C0396 code to appear on a 2014 Chevy Silverado?
Common causes include a faulty range actuator position sensor, damaged wiring or connectors in the circuit, or an issue with the transfer case control module (TCCM).
4. Can I drive my 2014 Silverado with the C0396 code activated?
You can drive the truck, but you may lose 4WD functionality, which can be risky in off-road conditions or poor weather. It’s best to address the issue promptly.
5. How do I diagnose the C0396 code in a 2014 Chevrolet Silverado?
Diagnosis involves scanning for codes, inspecting the wiring and connectors to the range actuator, testing the position sensor, and checking the transfer case control module for faults.
6. How do I fix the C0396 code on my 2014 Silverado?
Repairs may include replacing the range actuator position sensor, repairing damaged wiring or connectors, or reprogramming/replacing the transfer case control module.
7. Is the range actuator position sensor the same as the transfer case motor?
No, the range actuator position sensor is a separate component that monitors the position of the transfer case motor but is often integrated into the motor assembly.
8. What tools are needed to repair the C0396 code on a 2014 Silverado?
You’ll need an OBDII scanner, a multimeter for testing the circuits, and basic tools for accessing the transfer case components.
9. How much does it cost to fix the C0396 code on a 2014 Chevrolet Silverado?
Repair costs can vary but typically range from $200 to $600, depending on whether the sensor, wiring, or transfer case motor assembly needs replacement.
10. Can a software update fix the C0396 code on my 2014 Silverado?
In some cases, a software update for the transfer case control module may resolve the issue if it’s related to a programming error. However, hardware faults will require physical repairs.
