1. PRECAUTION
Be sure to read Precaution thoroughly before servicing.
After turning the ignition switch off, waiting time may be required before disconnecting the cable from the auxiliary negative (-) battery terminal.
2.PLACE FRONT WHEELS FACING STRAIGHT AHEAD
3.DISCONNECT CABLE FROM NEGATIVE AUXILIARY BATTERY TERMINAL
Wait at least 60 seconds after disconnecting the cable from the negative (-) auxiliary battery terminal to disable the SRS system.
If the airbag deploys for any reason, it may cause a serious accident.

4.REMOVE STEERING WHEEL ASSEMBLY
5.INSPECT SPIRAL CABLE SUB-ASSEMBLY
Check that the front wheels are facing straight ahead.
Check that the spiral cable sub-assembly is in the center position.
The connector is at the top.
The colored roller or the top of the flat cable U-turn can be checked from the check window.
| *A | Colored Roller (Visible Type) | *B | Flat Cable (Visible Type) |
| *a | Check Window | *b | Colored Roller |
| *c | Top of Flat Cable U-turn | - | - |
If the result is not as specified, it is possible that the spiral cable sub-assembly is broken. Replace the spiral cable sub-assembly with a new one.

7.REMOVE UPPER STEERING COLUMN COVER
8.REMOVE SPIRAL CABLE WITH SENSOR SUB-ASSEMBLY
Do not replace the spiral cable with sensor sub-assembly with the auxiliary battery connected and the ignition switch ON.
Do not rotate the spiral cable with sensor sub-assembly with the auxiliary battery connected and the ignition switch ON.
When rotating the spiral cable with sensor sub-assembly to check the operation of the spiral cable with sensor sub-assembly (checking for abnormal noise, checking the Data List, etc.), make sure to perform the inspection with the steering wheel assembly installed.
Disconnect each connector.
When disconnecting any airbag connector, take care not to damage the airbag wire harness.
Refer to How to Connect or Disconnect Airbag Connector:
Detach the claw and clip to remove the spiral cable with sensor sub-assembly.
9.REMOVE STEERING SENSOR
Remove the steering sensor from the spiral cable sub-assembly only when replacing the spiral cable sub-assembly.
Removing the steering sensor from the spiral cable sub-assembly without using a lock pin may result in a misaligned center position of the steering sensor. Therefore, make sure to use the lock pin provided with a new spiral cable sub-assembly when removing the steering sensor from the spiral cable sub-assembly.
Install the lock pin to the steering sensor.
Use the lock pin provided with a new spiral cable sub-assembly.
Do not remove the lock pin before the spiral cable sub-assembly is installed to the steering sensor.
Remove the steering sensor.
