Toyota Yaris: Spiral Cable / Installation

INSTALLATION

PROCEDURE

1. INSPECT SPIRAL CABLE WITH SENSOR SUB-ASSEMBLY

(a) 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.

(b) 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.

*a	Interlock
	Counterclockwise

(1) While pushing on the interlock indicated in the illustration. Make sure to 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.

*a	Interlock
	Clockwise

(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

(a) Align the guides and 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.

*a Lock Pin *b Guide

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

3. PLACE FRONT WHEELS FACING STRAIGHT AHEAD

4. INSTALL SPIRAL CABLE WITH SENSOR SUB-ASSEMBLY

(a) Check that the ignition switch is off.

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

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

(d) 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.

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

(f) Connect each connector.

NOTICE:

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