Diagnostic Procedure

STEP

INSPECTION

ACTION
1
CONFIRM BCM DTC

Yes
Go to the next step.
No
Go to Step 9.
2
INSPECT STEERING ANGLE SENSOR CONNECTOR AND TERMINALS
•  Switch the ignition to off.
•  Disconnect the negative battery cable.
•  Disconnect the steering angle sensor connector.
•  Inspect the connector and terminals (corrosion, damage, pin disconnection).
•  Is there any malfunction?
Yes
Repair or replace the connector or terminals, then go to Step 8.
No
Go to the next step.
3
INSPECT BCM CONNECTOR AND TERMINALS
•  Disconnect the BCM connector.

•  Switch the ignition to ON.
•  Measure the voltage at the following terminals (wiring harness-side):
―  Steering angle sensor terminal F
―  Steering angle sensor terminal D
―  Steering angle sensor terminal B
―  Steering angle sensor terminal C
•  Is there any voltage?
Yes
Repair or replace the wiring harness for a possible short to power supply, then go to Step 8.
No
Go to the next step.
6
INSPECT STEERING ANGLE SENSOR SIGNAL CIRCUIT FOR OPEN CIRCUIT
