CAN

STRG BRANCH LINE CIRCUIT

Diagnosis Procedure


1. CHECK CONNECTOR

1.Turn the ignition switch OFF.
2.Disconnect the battery cable from the negative terminal.
3.Check the following terminals and connectors for damage, bend and loose connection (unit side and connector side).
-Steering angle sensor
-Harness connector M22 and PCB harness side connector
Is the inspection result normal?
YES- GO TO 2.
NO- 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.





Is the measurement value within the specification?
YES- GO TO 3.
NO- GO TO 4.

3. CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the steering angle sensor. [1][2]Antilock Brakes / Traction Control Systems.
Is the inspection result normal?
YES (Present error)-Replace the steering angle sensor. Service and Repair.
YES (Past error)-Error was detected in the steering angle sensor branch line.
NO- Repair the power supply and the ground circuit.

4. CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

1.Disconnect the harness connector M22.
2.Check the continuity between the steering angle sensor harness connector and the harness connector.





Is the inspection result normal?
YES- Replace the PCB harness.
NO- Repair the harness between the steering angle sensor harness connector M37 and the harness connector M22.
