Title: SUPPLEMENTAL RESTRAINT SYSTEMS: SPIRAL CABLE: INSPECTION; 2016 - 2020 MY Sienna [12/2015 - ] |
INSPECTION
PROCEDURE
1. INSPECT SPIRAL WITH SENSOR CABLE SUB-ASSEMBLY (w/o Steering Heater)
(a) Visually check for defects with the spiral with sensor cable sub-assembly removed from the vehicle.
(1) The defects are as follows:
-
Scratches on the spiral with sensor cable sub-assembly
-
Small cracks the spiral with sensor cable sub-assembly
-
Dents on the spiral with sensor cable sub-assembly
-
Chips on the spiral with sensor cable sub-assembly
-
Cracks or other damage to the connector
OK:
No defects are found.
HINT:
If any of the defects is found, replace the spiral with sensor cable sub-assembly with a new one.
(b) Check the spiral with sensor cable sub-assembly.

NOTICE:
As the spiral with sensor cable sub-assembly may break, do not rotate the spiral with sensor cable sub-assembly more than the specified amount.
(1) Set the spiral with sensor cable sub-assembly to the center position.
(2) Measure the resistance between each terminal of the spiral with sensor cable sub-assembly according to the table below.
(3) After setting the spiral with sensor cable sub-assembly to the center position, rotate the spiral with sensor cable sub-assembly 2.5 times clockwise, and measure the resistance as shown. Then rotate the spiral with sensor cable sub-assembly 5 times counterclockwise, and measure the resistance as shown.
