3. CHECK STEERING ANGLE SENSOR HARNESS
1. Check CAN communication system. Refer to BRC-47, "CAN Communication Circuit". CAN Communication Circuit
2. Turn ignition switch OFF and disconnect steering angle sensor connector.
3. Check continuity between steering angle sensor harness connector M47 terminal 2 and ground.
4. Turn ignition switch ON and check voltage between steering angle sensor harness connector M47 terminal 3 and ground.
OK or NG
OK >> GO TO 4.
NG >> ^ Repair or replace malfunctioning components.
^ Perform the self-diagnosis, and make sure that the result shows "NO DTC IS DETECTED".
4. CHECK DATA MONITOR
