Inspection 5 Steering Angle Signal Malfunction1.CHECK CONNECTOR
1. Turn ignition switch OFF, disconnect RAS control unit harness connector and steering angle sensor harness connector, and check terminal for deformation, disconnection, looseness, etc.
2. Reconnect harness connector securely, and perform self-diagnosis.
With CONSULT-III
Without CONSULT-III
Is above displayed on self-diagnosis display?
YES >> GO TO 2.
NO >> Connector terminal connection is loose, damaged, open, or shorted. Repair or replace the terminal.
2.ADJUST NEUTRAL POSITION OF STEERING ANGLE SENSOR
Adjust the steering angle sensor neutral position, and then perform self-diagnosis again. Refer to BRC-8, "Adjustment of Steering Angle Sensor Neutral Position". Testing and Inspection
Is the result of self-diagnosis normal?
OK >> Inappropriate neutral position adjustment of steering angle sensor.
NG >> GO TO 3.
3.CHECK STEERING ANGLE SENSOR POWER SUPPLY AND GROUND CIRCUIT
1. Turn ignition switch OFF, and disconnect steering angle sensor harness connector M47.
2. Check continuity steering angle sensor harness connector M47 and ground.
3. Turn ignition switch ON, and then check voltage steering angle sensor harness connector M47 and ground.
OK or NG
OK >> GO TO 4.
NG >> Steering angle sensor power supply and ground circuit open or shorted. Repair or replace the applicable malfunctioning circuit.
4.DATA MONITOR
1. Connect steering angle sensor harness connector.
2. Select "DATA MONITOR" on "STEERING ANG" mode, and then check the steering angle.
OK or NG
OK >> RAS control unit malfunction. Replace RAS control unit.
NG >> Replace steering angle sensor and adjust neutral position of steering angle sensor. Refer to BRC-8, "Adjustment of Steering Angle Sensor Neutral Position". Testing and Inspection
