When it comes to diagnosing and repairing electrical issues, the Chevrolet C0201 04 Code can be a huge headache. This diagnostic trouble code usually indicates a fault in the Anti-lock Brake System (ABS) Enable Relay Contact Circuit and it can be caused by a variety of different factors. To help you better understand the different potential causes and solutions for the C0201 04 code, we have created a table outlining the common causes and potential solutions for this problem.
Chevrolet C0201 04 Code: Causes and Solutions
| Cause | Solution |
|---|---|
| C0201 04 or C120D | Check the circuits to the solenoid valve relay for any opens or shorts. |
| The EBCM detects an open in the circuits to the solenoid valve relay. | Check the EBCM for any faults. |
| The EBCM detects a stuck open solenoid valve relay. | Replace the solenoid valve relay. |
| The EBCM detects an short to battery in the circuits to the solenoid valve relay. | Repair or replace the circuits to the solenoid valve relay. |
| The EBCM detects a stuck closed solenoid valve relay. | Check the EBCM for any faults and repair or replace the solenoid valve relay. |
Diagnosing and Repairing the C0201 04 Code
When a technician receives a C0201 04 code, they must first properly diagnose the issue in order to determine the root cause of the problem. The most common cause is an open or short in the circuits to the solenoid valve relay. To diagnose this issue, the technician must use a diagnostic scanner to read the EBCM for any faults. If there are no faults detected, the technician must then check the circuits to the solenoid valve relay for any opens or shorts.
If an open or short is detected, the technician must then repair or replace the circuits to the solenoid valve relay. If the issue is not related to the circuits, the technician must then check the EBCM for any faults. If there are any faults detected, the technician must then replace the solenoid valve relay.
The Benefits of Resolving C0201 04 Code
Resolving the C0201 04 code can help restore the functionality of the Anti-lock Brake System (ABS) and can also help reduce the amount of time spent diagnosing and repairing electrical issues. Properly diagnosing and resolving this code can also help prevent other ABS-related issues from occurring in the future.
Conclusion
The Chevrolet C0201 04 Code can be a difficult diagnostic code to resolve, but with the right knowledge and tools, it can be resolved quickly and easily. Proper diagnosis and repair of this code can help restore the functionality of the ABS and can also help prevent other issues from arising in the future. If you are dealing with the Chevrolet C0201 04 Code, make sure to properly diagnose the issue and repair or replace the circuits or solenoid valve relay as necessary.
