Caution
Wait at least 30 seconds after disconnecting the battery
cable before doing any further work. The SRS system is
designed to retain enough voltage to deploy the air bag
for a short time even after the battery has been
disconnected, so serious injury may result from unin-
tended air bag deployment if work is done on the SRS
system immediately after the battery cable is discon-
nected.

Align the mating mark and “NEUTRAL” position indicator of
the clock spring, and, after turning the front wheels to the
straight-ahead position, install the clock spring to the
column switch.
Caution
If the clock spring’s mating mark, is not properly
aligned, the steering wheel may not be completely
rotational during a turn, or the flat cable within the
clock spring may be severed, obstructing normal
operation of the SRS and possibly leading to serious
injury to the vehicle’s driver.

TION

connector to the SRS diagnosis unit, be absolutely sure to
press down the lock lever of the SRS diagnosis unit.

the vehicle’s front wheels to the straight-ahead position

indicator of the clock spring.
Caution
Be sure when installing the steering wheel, that the
harness of the clock spring does not become caught
or tangled.
(2) After clamping, turn the steering wheel all the way in
both directions to confirm that steering is normal.
