INSTALLATION
PROCEDURE
1. INSPECT SPIRAL CABLE SUB-ASSEMBLY (w/o Steering Heater)
NOTICE:
If the steering sensor is installed to a misaligned spiral cable sub-assembly, DTCs for an abnormal steering sensor value such as DTC B1801, C1231 and C1433 will be stored and it will be impossible to correct the problem. If this happens, replace the spiral cable with sensor sub-assembly with a new one.
(a) Check if the spiral cable sub-assembly is centered. HINT: When the spiral cable sub-assembly is centered, the part (A) is positioned at the top and the flat cable shown in the illustration is visible. |
|
(b) If the spiral cable sub-assembly is not centered, center it.
(1) While pushing on the interlock shown in the illustration, rotate the spiral cable sub-assembly counterclockwise slowly by hand until it stops. NOTICE:
|
|
(2) While pushing on the interlock shown in the illustration, rotate the spiral cable sub-assembly clockwise approximately 2.5 times to the position where the alignment marks are aligned and the flat cable shown in the illustration is visible. HINT: The spiral cable sub-assembly can be rotated approximately 2.5 turns to both the left and right from the center. |

3. INSTALL SPIRAL CABLE WITH SENSOR SUB-ASSEMBLY
NOTICE:
(a) Check that the ignition switch off.
(b) Check that the cable is disconnected from the negative (-) battery terminal.
CAUTION:
Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.
(c) Check that the front wheels are aligned facing straight ahead.
(d) Engage the claws to install the spiral cable with sensor sub-assembly. |
