PROCEDURE

1. INSPECT SPIRAL CABLE SUB-ASSEMBLY

(1) Check if the spiral cable sub-assembly is centered.

OK:

The connector is at the top.

The matchmarks are aligned.

The top of the flat cable U-turn can be checked from the check window.

*a	Interlock	*b	Check Window
*c	Matchmark	*d	Top of Flat Cable U-turn
	Rotation Direction	-	-

(1) If the spiral cable sub-assembly is not centered, center it.

NOTICE:

Make sure to observe the following precautions, otherwise the spiral cable sub-assembly may be damaged.

• Release the interlock before rotating the spiral cable sub-assembly.
• Do not rotate the spiral cable sub-assembly using the airbag wire harness.
• Do not rotate the spiral cable sub-assembly with excessive force.

1. While pushing on the interlock indicated in the illustration, rotate the spiral cable with sensor sub-assembly counterclockwise slowly by hand until it stops.

   NOTICE:

   Make sure to rotate the spiral cable with sensor sub-assembly counterclockwise. If rotated clockwise, it may be damaged or centering may no longer be possible.

   HINT:

   The interlock operates at the top and bottom of the connector.

2. If the spiral cable with sensor sub-assembly stops rotating and the connector has moved past the bottom, return the connector to the bottom as shown in the illustration.
3. While pushing on the interlock, rotate the spiral cable with sensor sub-assembly clockwise approximately 2.5 times to move the connector from the bottom to the top.

   NOTICE:

   If the connector is rotated clockwise from the bottom 5 times or more, the spiral cable with sensor sub-assembly may be damaged.

   HINT:

   The interlock operates at the top and bottom of the connector.

4. Check that the spiral cable with sensor sub-assembly is center position.

   OK:

   The connector is at the top.

   The matchmarks are aligned.

   The colored roller or the top of the flat cable U-turn can be checked from the check window.

   NOTICE:

   If the spiral cable with sensor sub-assembly cannot be centered, it is possible that the spiral cable sub-assembly is broken. Replace the spiral cable sub-assembly with a new one.

2. INSTALL STEERING SENSOR

NOTICE: Remove the steering sensor from the spiral cable sub-assembly only when replacing the spiral cable sub-assembly.

(a) Align the 2 pins and 2 guides, and engage the 6 claws to install the spiral cable sub-assembly to the steering sensor.

(1) Align the guides to install the steering sensor to the spiral cable sub-assembly.

(2) Engage the claws to install the steering sensor to the spiral cable sub-assembly.

NOTICE:

• Do not remove the lock pin before the spiral cable sub-assembly is installed to the steering sensor.
• Do not damage the pins of the spiral cable sub-assembly or guides of the steering sensor.
• The spiral cable sub-assembly can be rotated up to 30° even when the interlock is engaged. Therefore, make sure that both guides are aligned properly when installing the spiral cable sub-assembly to the steering sensor.

(3) Remove the lock pin from the steering sensor.

3. PLACE FRONT WHEELS FACING STRAIGHT AHEAD

4. INSTALL SPIRAL CABLE WITH SENSOR SUB-ASSEMBLY

NOTICE: Do not replace the spiral cable with sensor sub-assembly with the battery connected and the ignition switch on (IG). Do not rotate the spiral cable with sensor sub-assembly with the battery connected and the ignition switch on (IG). 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 DTC, Data list, etc.) make sure to perform the inspection with the steering wheel assembly installed.

(1) Check that the ignition switch is off.

(2) Check that the cable is disconnected from the negative (-) auxiliary battery terminal.

CAUTION:

• Wait at least 90 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.

(1) Check that the front wheels are aligned facing straight ahead.

(2) Set the turn signal switch to the neutral position.

NOTICE:

If it is not in the neutral position, the turn signal switch cancel ratchet may snap.

(1) Engage the claw and clip to install the spiral cable with sensor sub-assembly.

(2) Install the wire harness to the spiral cable with sensor sub-assembly.

(3) Connect each connector.

(4) Connect the airbag connector.

NOTICE:

When connecting any airbag connector, take care not to damage the airbag wire harness.

5. INSTALL UPPER STEERING COLUMN COVER

6. INSTALL LOWER STEERING COLUMN COVER

7. ADJUST SPIRAL CABLE WITH SENSOR SUB-ASSEMBLY

NOTICE: Do not rotate the spiral cable with sensor sub-assembly with the battery connected and the ignition switch on (IG).

(1) Check that the ignition switch is off.

(2) Check that the cable is disconnected from the negative (-) auxiliary battery terminal.

CAUTION:

• Wait at least 90 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.

(1) Check that the spiral cable with sensor sub-assembly is center position.

OK:

The connector is at the top.

The top of the flat cable U-turn can be checked from the check window.

(1) If the spiral cable with sensor sub-assembly is not centered, center it.

NOTICE:

Failure to observe the following precautions may result in damage to the spiral cable with sensor sub-assembly.

• When rotating the spiral cable with sensor sub-assembly, make sure to push on the interlock to release the interlock.
• Do not turn the spiral cable with sensor sub-assembly using the airbag wire harness.
• Do not forcibly rotate the part.

1. While pushing on the interlock indicated in the illustration, rotate the spiral cable with sensor sub-assembly counterclockwise slowly by hand until it stops.

   NOTICE:

   If the connector is rotated clockwise from the bottom 5 times or more, the spiral cable with sensor sub-assembly may be damaged.

   HINT:

   The interlock operates at the top and bottom of the connector.

2. If the spiral cable with sensor sub-assembly stops rotating and the connector has moved past the bottom, return the connector to the bottom as shown in the illustration.
3. While pushing on the interlock, rotate the spiral cable with sensor sub-assembly clockwise approximately 2.5 times to move the connector from the bottom to the top.

   NOTICE:

   If the connector is rotated clockwise from the bottom 5 times or more, the spiral cable with sensor sub-assembly may be damaged.

   HINT:

   The interlock operates at the top and bottom of the connector.

4. Check that the spiral cable with sensor sub-assembly is center position.

   OK:

   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.

   NOTICE:

   If the spiral cable sub-assembly cannot be centered, it is possible that the spiral cable sub-assembly is broken. Replace the spiral cable sub-assembly with a new one.
