Diagnosis Procedure

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
   • CAN gateway (Models with around view monitor system)

Is the inspection result normal?

YES - 1 

Models with around view monitor system: GO TO STEP 2  .

YES - 2 

Models without around view monitor system: GO TO STEP 3  .

NO 

Repair the terminal and connector.

1. Disconnect the connector of CAN gateway.
2. Check the continuity between the CAN gateway harness connector terminals.

   CAN gateway harness connector			Continuity
   Connector No.	Terminal No.
   M24	4	6	Existed
   	10	12	Existed

Is the inspection result normal?

YES 

GO TO STEP 3  .

NO 

Check the harness and repair the root cause (CAN communication circuit).

1. Connect the connector of CAN gateway (Models with around view monitor system).
2. Disconnect the connector of steering angle sensor.
3. Check the resistance between the steering angle sensor harness connector terminals.

   Steering angle sensor harness connector			Resistance (Ω)
   Connector No.	Terminal No.
   M77	5	2	Approx. 54 - 66

Is the measurement value within the specification?

YES 

GO TO STEP 4  .

NO 

Repair the steering angle sensor branch line

Check the power supply and the ground circuit of the steering angle sensor. Refer to DIAGNOSIS PROCEDURE .

Is the inspection result normal?

YES (Present error) 

Replace the steering angle sensor. Refer to REMOVAL AND INSTALLATION .

YES (Past error) 

Error was detected in the steering angle sensor branch line.

NO 

Repair the power supply and the ground circuit.
