INSTALLATION

PROCEDURE

1. INSPECT SPIRAL CABLE SUB-ASSEMBLY

NOTICE:

If the steering sensor is installed to a misaligned spiral cable sub-assembly, spiral cable with sensor sub-assembly malfunction DTCs, such as DTC B1801, C1231 and C1433, will be stored and it will be impossible to clear them. If this happens, replace the spiral cable sub-assembly and steering sensor with a new one.

(a) Check if the spiral cable sub-assembly is centered.

OK:
  • The connector is positioned at the top.
  • The alignment marks are aligned correctly.
  • The colored roller or flat cable can be seen in the inspection window.

(b) If the spiral cable sub-assembly is not centered, center it.

NOTICE:

Make sure to observe the following precautions, otherwise the spiral cable sub-assembly may be damaged.

  • Release the interlock before rotating the spiral cable sub-assembly.
  • Do not rotate the spiral cable sub-assembly using the airbag wire harness.
  • Do not rotate the spiral cable sub-assembly with excessive force.

(1) While pushing on the interlock shown in the illustration, rotate the spiral cable sub-assembly counterclockwise slowly by hand until it stops.

Rotation Direction

NOTICE:

If the spiral cable sub-assembly is rotated clockwise in this step, it may be damaged and may no longer be able to be centered. Make sure to only rotate the spiral cable sub-assembly counterclockwise.

HINT:

If the interlock is engaged, the spiral cable sub-assembly will lock when the connector is near at the top or bottom of the rotation of the spiral cable sub-assembly.

(2) If the connector is not positioned at the bottom of the rotation of the spiral cable sub-assembly when the spiral cable sub-assembly is turned until it stops, turn the spiral cable sub-assembly clockwise until the connector is positioned at the bottom as shown in the illustration.
