Note
• The steering angle initialization value of the BCM is stored using the battery power supply. Therefore, the battery power supply of the BCM is cut and the stored steering angle initialization value is cleared when any of the following items are performed. DTC C1306 is stored in the memory.
― Negative battery cable disconnection
― BCM connector disconnection
― steering angle sensor connector disconnection
― Fuse (ROOM) removal
― Wiring harness disconnection between battery and BCM connector
― Wiring harness disconnection between BCM connector and steering angle sensor connector

DTC
C1306
Steering angle sensor (abnormal initialization) system
DETECTION CONDITION
• The steering angle sensor detects that the initialization procedure has not been performed.
POSSIBLE CAUSE
• The negative battery cable connector was disconnected previously.
• The steering angle sensor connector was disconnected previously.
• The BCM connector was disconnected previously.
• The fuse (ROOM) was removed previously.
• The initialization procedure for the steering angle sensor has not been performed.
• BCM malfunction
• Steering angle sensor malfunction
• DSC HU/CM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY INITIALIZATION PROCEDURE.
• Has the steering angle sensor initialization procedure been performed?
Yes
Go to the next step.
No
Perform the steering angle sensor initialization procedure, then go to Step 3.
(See STEERING ANGLE SENSOR INITIALIZATION PROCEDURE.)
2
INSPECT FOR BCM MALFUNCTION
• Turn the ignition switch to the LOCK position.
• Using the M-MDS, perform the DTC inspection for the BCM. (See DTC INSPECTION [BCM].)
• Are any DTCs detected?
Yes
Go to applicable DTC inspection.
(See DTC TABLE [BCM].)
No
Go to the next step.
3
VERIFY DTC TROUBLESHOOTING COMPLETED
• Clear the DTC from the memory. (See ON-BOARD DIAGNOSIS.)
• Is the same DTC present?
Yes
Repeat the inspection from Step 1.
If the malfunction occurs again, replace the DSC HU/CM, then go to the next step.
(See DSC HU/CM REMOVAL/INSTALLATION [L.H.D.].)
(See DSC HU/CM REMOVAL/INSTALLATION [R.H.D.].)
No
Go to the next step.
4
VERIFY AFTER REPAIR PROCEDURE
• Are any other DTCs present?
Yes
Go to the applicable DTC inspection.
(See ON-BOARD DIAGNOSIS.)
No
DTC troubleshooting completed.
