What is C0961?
The Diagnostic Trouble Code (DTC) C0961 indicates a problem with the Chassis Control Module (CCM) in vehicles, particularly affecting models from manufacturers like Ford and General Motors (GM) from 2015 to 2020. This code suggests that the CCM is not communicating properly with other control modules within the vehicle. The CCM is responsible for various functions, including stability control, traction control, and sometimes even electronic parking brakes. When this code is triggered, you may notice symptoms like the traction control light illuminating on the dashboard or unusual vehicle behavior during acceleration or braking. Real-world implications of this code can be significant, as it might lead to reduced vehicle stability or even safety issues if left unaddressed. Ignoring this code could lead to further electrical problems, increased repair costs, and potentially dangerous driving conditions. It's crucial for vehicle owners to understand that C0961 is not just a minor glitch but an indication of a communication breakdown that could affect overall vehicle performance.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0961 is present:
- Check engine light illuminates and remains on, indicating a persistent issue.
- Traction control light may flash or stay on, leading to potential loss of vehicle stability.
- Vehicle may exhibit erratic behavior, such as unexpected acceleration or braking issues.
- Difficulty engaging the electronic parking brake, leading to potential safety risks when parked.
- Increased fuel consumption due to improper engine management caused by the CCM issue.
Possible Causes
Most common causes of C0961 (ordered by frequency):
- Faulty Chassis Control Module (CCM) - Most common cause, accounting for about 60% of cases. This could be due to internal failures or water damage.
- Wiring issues - Loose, damaged, or corroded wiring connections can lead to communication failures between the CCM and other modules, typically seen in 20% of cases.
- Software glitches - Occasionally, the vehicle's software may need updating, leading to miscommunication, making up 10% of cases.
- Faulty sensors - Issues with wheel speed sensors or steering angle sensors can also trigger this code, accounting for around 5% of cases.
- Grounding issues - Poor grounding connections can create communication problems, which are less common but can lead to serious electrical failures.
