C0218 SATURN Possible Causes

  • 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

How do I fix code C0218 SATURN?

  Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.

Cost of diagnosing the C0218 SATURN code

  The cost of diagnosing the C0218 SATURN code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.

Possible Symptoms

  • Anti-Lock Brake System (ABS) Warning Light ON
  • Engine Light ON (or Service Engine Soon Warning Light)

C0218 SATURN 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.
