(air bag module) and column switch body (steering
column).

contact connections like horn contact as in the past,
between the air bag module and SRS diagnosis unit,
between the horn switch and body wiring harness, and
between the remote control switch and body wiring
harness.
The clock spring consists of a neutral position indication
mechanism, flat cable, upper case, lower case, rotor,
etc.

the rotor and the other end mounted to the upper case.
The upper and lower cases are mounted to the steering
column. The rotor is coupled with the steering shaft.

round the rotor or loosened, and operates with the rotor
as the steering wheel is turned.

disassembled.
