2. INSTALL STEERING SENSOR

(a) Align the 2 pins and 2 guides, and engage the 6 claws to install the steering sensor to the spiral cable sub-assembly.

NOTICE:

Do not remove the lock pin before the steering sensor is installed to the spiral cable sub-assembly.
Do not damage the pins of the spiral cable sub-assembly and guides of the steering sensor.
The spiral cable sub-assembly can be rotated up to 30° even when the interlock is engaged. Therefore, make sure that both guides are aligned properly when installing the steering sensor to the spiral cable sub-assembly.
