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.
