C0220 GMC Code - Longitudinal Accelerometer Signal Voltage
Quick Answer
The Vehicle Stability Enhancement System (VSES) is activated when the Electronic Brake Control Module (EBCM) determines that the desired yaw rate does not match the actual yaw rate. Common causes include Faulty Electronic Brake Control Module (EBCM), Electronic Brake Control Module (EBCM) harness is open or shorted, Electronic Brake Control Module (EBCM) 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.
- What it means
- C0220 GMC indicates Longitudinal Accelerometer Signal Voltage.
- Common causes
- Common causes include Faulty Electronic Brake Control Module (EBCM), Electronic Brake Control Module (EBCM) harness is open or shorted, Electronic Brake Control Module (EBCM) circuit poor electrical connection.
- Severity
- High - diagnose this code as soon as possible.
- Can I drive?

Code C0220 GMC Description
- Zero yaw rate.
- Zero lateral acceleration.
- Zero longitudinal acceleration.
The sensor bias compensates, during VSES initialization, for sensor mounting alignment errors, electronic signal errors, temperature changes, and manufacturing differences.
What are the Possible Causes of the DTC C0220 GMC?
- Faulty Electronic Brake Control Module (EBCM)
- Electronic Brake Control Module (EBCM) harness is open or shorted
- Electronic Brake Control Module (EBCM) circuit poor electrical connection
