Tester Display Measurement Item Range Normal Condition Diagnostic Note
Steering Angle Signal Information Steering angle value (Rotation to the left side is positive) Min.: -3072.0 deg
Max.: 3070.5 deg 		Turning left: 0.0 to 3070.5 deg

b.

Save the steering angle signal information to the GTS memory.


NOTICE:
·

If the value is +/- 360 deg (+/-15 deg), the steering sensor was incorrectly installed by 1 rotation.

·

If the value is +/- 720 deg (+/-15 deg), the steering sensor was incorrectly installed by 2 rotations.

·

In situations other than the above, the steering sensor may have been incorrectly installed by 3 or more rotations.

In this case, it is possible that the proper installation or removal procedures were not followed, and the steering sensor may have been damaged.

NOTICE:
·

Be sure to disconnect the cable from the negative (-) auxiliary battery terminal before removing the spiral cable with sensor sub-assembly.

HINT:

If the cable is not disconnected from the negative (-) auxiliary battery terminal, it may not be possible to obtain an accurate steering sensor zero point.


·

Do not disconnect the steering sensor from the spiral cable.

Based on the internal steering angle value that was saved to the GTS memory earlier, rotate the spiral cable with sensor sub-assembly.


NOTICE:
·

Rotate the steering sensor without disconnecting it from the spiral cable.

·

Make sure to follow the adjustment method shown in the table.

·

Failure to observe the following precautions may result in damage to the spiral cable with sensor sub-assembly.

-

When rotating the spiral cable with sensor sub-assembly, make sure to push on the interlock to release the interlock.

-

Do not turn the spiral cable with sensor sub-assembly using the airbag wire harness.

-

Do not forcibly rotate the part.

-

Make sure to perform the correct number of rotations in the correct direction.




Steering Angle Signal Information Correction Method
360 deg (+/-15 deg) Rotate clockwise (to the right), 1 rotation.
- 360 deg (+/-15 deg) Rotate counterclockwise (to the left), 1 rotation.
