C0218 Chevrolet 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.

Code C0218 Chevrolet Description

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. The desired yaw rate is calculated from the measured steering wheel position, vehicle speed, and lateral acceleration. With no sensor bias present, a volt signal from these sensors is interpreted by the EBCM respectively as follows:
- 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.
