INSPECTION

PROCEDURE

1. INSPECT SPIRAL CABLE SUB-ASSEMBLY

NOTICE:

Do not remove the steering sensor from the spiral cable sub-assembly when inspecting the spiral cable sub-assembly.
Remove the steering sensor from the spiral cable sub-assembly only when replacing the spiral cable sub-assembly.

(a) Visually check the spiral cable sub-assembly for defects.

(1) The defects are as follows:

Scratches
Small cracks
Dents
Chips
Cracks or other damage to the connector
OK:

No defects are found.

If any of the defects is found, replace the spiral cable sub-assembly with a new one.

(b) Check the spiral cable sub-assembly.

w/ Heated Steering Wheel System

w/ Lane tracing assist system and Dynamic radar cruise control system

Component without harness connected

(Spiral Cable Sub-assembly)

Interlock

NOTICE:

When rotating the spiral cable sub-assembly, make sure to push on the interlock shown in the illustration to release the interlock mechanism.
As the spiral cable sub-assembly may break, do not rotate the spiral cable sub-assembly more than the specified amount.

(1) Set the spiral cable sub-assembly to the center position.

(2) Measure the resistance between each terminal of the spiral cable sub-assembly according to the value(s) in the table below.

(3) After setting the spiral cable sub-assembly to the center position, rotate the spiral cable sub-assembly 2.5 times clockwise, and measure the resistance according to the value(s) in the table below. Then rotate the spiral cable sub-assembly 5 times counterclockwise, and measure the resistance according to the value(s) in the table below.

(4) After setting the spiral cable sub-assembly to the center position, rotate the spiral cable sub-assembly 2.5 times clockwise. Then while rotating the spiral cable sub-assembly 5 times counterclockwise, measure the resistance according to the value(s) in the table below.

Standard Resistance:

H60-2(ECC) - z2-12(ECC)	Always	3 Ω or less
H60-4(EAU) - z2-10(EAU)	Always	3 Ω or less
H60-5(AU2) - z2-9(AU2)	Always	3 Ω or less
H60-6(DIST) - z2-8(DIST)	Always	3 Ω or less
H60-7(HO) - A(HO)	Always	3 Ω or less
H60-9(ILL-) - z2-6(ILL-)	Always	3 Ω or less
H60-10(+DP2) - z2-5(+DP2)	Always	3 Ω or less
H60-11(+DP) - z2-4(+DP)	Always	3 Ω or less
H60-12(AU1) - z2-3(AU1)	Always	3 Ω or less
H60-13(CCS) - z2-2(CCS)	Always	3 Ω or less
H60-14(IL+2) - z2-1(IL+2)	Always	3 Ω or less
H38-1(D+) - z3-2(D+)	Always	Below 1 Ω
H38-2(D-) - z3-1(D-)	Always	Below 1 Ω
H72-2(EHT) - Z16-1(EHT)	Always	Below 1 Ω
H72-4(BHT) - Z16-4(BHT)	Always	Below 1 Ω

If the result is not as specified, replace the spiral cable sub-assembly.
