SUPPLEMENTAL RESTRAINT SYSTEM STEERING WHEEL & COLUMN 2A – 65
CAUTION:
The wheels of the vehicle must be straight ahead and the
steering column in the "LOCK" position before
disconnecting the steering wheel. Failure to do so will
cause the coil assembly to become uncentered which will
cause damage to the coil assembly.
1. Front Console Assembly
1) Remove the transmission (for M/T) and transfer
control lever knob.
2) Disconnect the wiring harness connectors.
2. Lower Cluster Assembly
3. Steering Lower Cover
Remove the engine hood opening lever.
4. Inflator Module
1) Loosen the inflator module fixing bolt from
behind the steering wheel assembly using a
TORX
driver or equivalent until the inflator
module can be released from steering assembly.
2) Disconnect the yellow 2way SRS connector
located behind the inflator module.
WARNING
THE INFLATOR MODULE SHOULD ALWAYS BE CARRIED
WITH THE URETHANE COVER AWAY FROM YOUR BODY
AND SHOULD ALWAYS BE LAID ON A FLAT SURFACE
WITH THE URETHANE SIDE UP. THIS IS NECESSARY
BECAUSE A FREE SPACE IS PROVIDED TO ALLOW THE
AIR CUSHION TO EXPAND IN THE UNLIKELY EVENT OF A
ACCIDENTAL DEPLOYMENT. OTHERWISE, PERSONAL
INJURY MAY RESULT.

4. Inflator Module
1) Support the module and carefully connect the
module connector.
CAUTION:
·Never use the air bag assembly from another vehicle.
Use only the air bag assembly for "UBS".
·When replace the inflator module, use only same parts
number assembly. If different parts number assembly is
installed, the air bag system can not function correctly
because it has different characteristic.
NOTE:
Pass the lead wire through the tabs on the plastic
cover (wire protector) of inflator to prevent lead wire
from being pinched.
2) Secure the module with one bolt to relieve
weight on the connector wire.
3) Tighten bolts to specified sequence as figure.
