Steering Angle Sensor Branch Line CircuitNKS004O9
INSPECTION PROCEDURE
1. CHECK CONNECTOR
1. Turn the ignition switch OFF.
2. Disconnect the battery cable from the negative terminal.
3. Check the terminals and connectors of the steering angle sensor for damage, bend and loose connection (unit side and connector side).
OK or NG
OK >> GO TO 2.
NG >> Repair the terminal and connector.
2. CHECK HARNESS FOR OPEN CIRCUIT
1. Disconnect the connector of steering angle sensor.
2. Check the resistance between the steering angle sensor harness connector terminals.
OK or NG
OK >> GO TO 3.
NG >> Repair the steering angle sensor branch line.
3. CHECK POWER SUPPLY AND GROUND CIRCUIT
Check the power supply and the ground circuit of steering angle sensor. Refer to BRC-15, "
Schematic" .
OK or NG
OK >>
Present error: Replace the steering angle sensor. Refer to BRC-63, "STEERING ANGLE SEN-
SOR" .

Past error: Error was detected in the steering angle sensor branch line.
NG >> Repair the power supply and the ground circuit.
