Steering Angle Sensor Circuit Malfunction (C1231/31)
DESCRIPTION
The steering angle sensor signal is sent to the skid control ECU via the CAN
communication system. When there is a malfunction in the CAN communication system,
it will be detected by the steering angle sensor zero point malfunction diagnostic ...
