C0396 2017 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 2017 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 2017 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 2017 Chevrolet Silverado Code
1. What does the OBDII code C0396 mean on a 2017 Chevrolet Silverado?
C0396 indicates an issue with the Range Actuator Position Sensor Circuit, which is part of the transfer case system in the vehicle's drivetrain.
2. What are the common symptoms of the C0396 code?
Common symptoms include the "Service 4WD" light turning on, the inability to shift between 4WD modes, or erratic transfer case operation.
3. What causes the C0396 code to appear?
The code can be triggered by a faulty range actuator position sensor, damaged wiring or connectors in the circuit, or an issue with the transfer case control module.
4. Can a bad range actuator cause drivability issues?
Yes, a malfunctioning range actuator can prevent proper engagement of 4WD modes, potentially impacting traction and off-road performance.
5. How do you diagnose the C0396 code?
Diagnosis involves scanning for codes, visually inspecting the wiring and connectors, and testing the range actuator position sensor for proper operation using a multimeter.
6. Can I still drive my Silverado with the C0396 code?
While the vehicle may still be drivable in 2WD, the 4WD system may not function as intended, which could be problematic in certain driving conditions.
7. How do you fix the C0396 code?
Repairing the code often involves replacing the range actuator position sensor, repairing damaged wiring or connectors, or reprogramming the transfer case control module if necessary.
8. How much does it cost to fix the C0396 code?
The cost can vary depending on the specific repair needed, but replacing the range actuator position sensor typically costs between $200 and $500, including parts and labor.
9. Can clearing the code fix the problem?
Clearing the code may temporarily reset the warning light, but the underlying issue must be addressed to prevent the code from returning.
10. Is the C0396 code a common issue on 2017 Chevrolet Silverados?
The C0396 code is not extremely common but can occur, especially on vehicles frequently used in 4WD or off-road conditions where the transfer case components are heavily utilized.
