INSTALLATION

PROCEDURE

1. INSPECT SPIRAL CABLE SUB-ASSEMBLY

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

OK:

  • The connector is positioned at the top.
  • The alignment marks are aligned correctly.
  • The flat cable can be seen in the inspection window.

(b) 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 shown in the illustration, rotate the spiral cable sub-assembly counterclockwise slowly by hand until it stops.

Rotation Direction

NOTICE:

If the spiral cable sub-assembly is rotated clockwise in this step, it may be damaged and may no longer be able to be centered. Make sure to only rotate the spiral cable sub-assembly counterclockwise.

HINT:

If the interlock is engaged, the spiral cable sub-assembly will lock when the connector is near at the top or bottom of the rotation of the spiral cable sub-assembly.

(2) If the connector is not positioned at the bottom of the rotation of the spiral cable sub-assembly when the spiral cable sub-assembly is turned until it stops, turn the spiral cable sub-assembly clockwise until the connector is positioned at the bottom as shown in the illustration.

NOTICE:

If the spiral cable sub-assembly is rotated clockwise 5 times or more from the point at which it stops and the connector is positioned at the bottom, the spiral cable sub-assembly may be damaged.

HINT:

If the interlock is engaged, the spiral cable sub-assembly will lock when the connector is near at the top or bottom of the rotation of the spiral cable sub-assembly.

(4) Check that the spiral cable sub-assembly is centered.

2. INSTALL 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.

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.

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

3. INSTALL SPIRAL CABLE WITH SENSOR SUB-ASSEMBLY

NOTICE:

  • Do not remove/install the spiral cable with sensor sub-assembly with the auxiliary battery connected and the ignition switch (for Gasoline Model) or power switch (for HV Model) on (IG).
  • Do not rotate the spiral cable with sensor sub-assembly without the steering wheel assembly installed, with the auxiliary battery connected and the ignition switch (for Gasoline Model) or power switch (for HV Model) on (IG).
  • Ensure that the steering wheel assembly is installed and aligned straight when inspecting the steering sensor.

(a) Check that the ignition switch (for Gasoline Model) or power switch (for HV Model) is off.

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

CAUTION:

for TMC Made:

  • Wait at least 60 seconds after disconnecting the cable from the negative (-) auxiliary battery terminal to disable the SRS system.

for TMMMS Made:

  • Wait at least 90 seconds after disconnecting the cable from the negative (-) auxiliary battery terminal to disable the SRS system.

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

(d) Engage the claw and 2 clips to install the spiral cable with sensor sub-assembly.

(e) Install the wire harness to the spiral cable with sensor sub-assembly as shown in the illustration.

Install in this Direction

(f) Connect each connector.

7. INSPECT AND ADJUST SPIRAL CABLE WITH SENSOR SUB-ASSEMBLY

(a) Check that the ignition switch (for Gasoline Model) or power switch (for HV Model) is off.

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

CAUTION:

for TMC Made:

  • Wait at least 60 seconds after disconnecting the cable from the negative (-) auxiliary battery terminal to disable the SRS system.

for TMMMS Made:

  • Wait at least 90 seconds after disconnecting the cable from the negative (-) auxiliary battery terminal to disable the SRS system.
