Replacement And Installation Notes
Before starting, disconnect the vehicle battery and secure the car. Removal normally requires freeing the module from its bracket, disconnecting the electrical connector and brake lines. Brake fluid will be released when lines are disconnected, so prepare suitable collection and later perform a full brake bleed. After physical replacement the unit may require pairing or coding with the vehicle diagnostic tool and a complete brake system bleed. These steps are recommended to be performed by a professional or an experienced DIY technician.
