DESCRIPTION
Steering angle sensor (spiral cable with sensor sub-assembly) signals are sent to the skid control ECU (master cylinder solenoid) via the CAN communication system. When there is a malfunction in the CAN communication system, it is detected by the steering angle sensor zero point malfunction diagnostic function.
