Code C1241 GMC Description

The Variable Effort Steering (VES) system uses the Electronic Brake Control Module (EBCM) to provide a control and return circuit for the VES actuator. The EBCM commands current from 0-619 mA depending on vehicle speed and steering position sensor signal voltage input. The EBCM compares the commanded and feedback currents to detect malfunctions in the VES actuator or the circuits to the actuator.
