INSTALLATION
CAUTION / NOTICE / HINT
CAUTION:
Some of these service operations affect the SRS airbag system. Read the precautionary notices concerning the SRS airbag system before servicing (See page
![2016 - 2020 MY Sienna [12/2015 - ]; SUPPLEMENTAL RESTRAINT SYSTEMS: AIRBAG SYSTEM: PRECAUTION](/t3Portal/stylegraphics/info.gif)
).
PROCEDURE
1. INSTALL SPIRAL WITH SENSOR CABLE SUB-ASSEMBLY
(a) Check that the ignition switch is off.
(b) Check that the cable is disconnected from the negative (-) battery terminal.
CAUTION:
Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.
(c) Confirm that the front tires face straight forward.
(d) Confirm that the turn signal switch is in the neutral position.
NOTICE:
Perform the operation when the turn signal switch is in the neutral position. Otherwise, the turn signal pin will break.
(e) Engage the 3 claws to install the spiral with sensor cable sub-assembly.
NOTICE:
When replacing the spiral cable with sensor sub-assembly with a new one, brake off and remove the lock pin before installing the steering wheel assembly.
(f) w/ Steering Heater:
(1) Connect the steering heater connector.
(g) Connect the airbag connector.
(h) Connect the connector.
(i) Connect the steering angle sensor connector.
CAUTION:
- Do not remove the steering angle sensor from the spiral with sensor cable sub-assembly.
- If there is a malfunction in the steering angle sensor, replace the spiral with sensor cable sub-assembly.
2. INSTALL UPPER STEERING COLUMN COVER
3. INSTALL LOWER STEERING COLUMN COVER
4. ADJUST SPIRAL WITH SENSOR CABLE SUB-ASSEMBLY
HINT:
Perform the following procedure only when reusing the spiral cable with sensor sub-assembly.
(a) Check that the ignition switch is off.
(b) Check that the cable is disconnected from the negative (-) battery terminal.
CAUTION:
Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.
(c) Check the check window shown in the illustration.
HINT:
When the spiral with sensor cable sub-assembly is centered, the connector is at the top and the conditions below can be checked.
-
w/o Steering Heater:
With the steering wheel straight ahead, align the matchmarks to check the colored roller from the check window.
-
w/ Steering Heater:
With the steering wheel straight ahead, align the matchmarks to check the U-turn point of the cable from the check window.

(e) Rotate the spiral with sensor cable sub-assembly counterclockwise slowly by hand until it stops. CAUTION: Do not turn the spiral cable sub-assembly using the airbag wire harness. |
|
(f) Rotate the spiral with sensor cable sub-assembly 2.5 times clockwise from the lock position to align the matchmarks and check the check window.
HINT:
- The spiral with sensor cable sub-assembly will rotate approximately 2.5 turns to both the left and right from the center.
- When the spiral with sensor cable sub-assembly is centered, the connector is at the top and the conditions below can be checked.
-
w/o Steering Heater:
With the steering wheel straight ahead, align the matchmarks to check the colored roller from the check window.
