MAINTENANCE AND REPAIR
ON–VEHICLE SERVICE
SERVICE PRECAUTION
CAUTION : The sensing and diagnostic mod-
ule(SDM) can maintain sufficient voltage to
deploy the airbags and pretensioners for 1 min-
ute after the ignition is OFF and the fuse has been
removed. If the airbags and pretensioners are not
disconnected, do not begin service until one
minute has passed after disconnecting power to
SDM. If the airbags are disconnected, service can
be excuted immediately without waiting for one–
minute time period to expire. Failure to tempo-
rarily disable the SIR during service can result in
unexpected deployment, personal injury and un-
necessary SIR repairs.
DISABLING THE SUPPLEMENTAL
INFLATABLE RESTRAINTS(SIR)
1. Turn the steering wheel to the straight–ahead posi-
tion.
2. Turn the ignition switch to LOCK and remove the
key.
3. Remove the airbag fuse F1 in the I/P fuse block
and wait more than one minute for SIR capacitor to
discharge.
ENABLING THE SUPPLEMENTAL
INFLATABLE RESTRAINTS(SIR)
1. Insert the airbag fuse F8 in the I/P fuse block.
2. Turn the ignition switch to ON and verify that the
airbag indicator flashes seven times and turns OFF.
If it does not operate as described, perform the”
SIR Diagnostic System Check” referring in this sec-
tion.
CAUTION : While turning the ignition switch,
staying well away from the inflator modules, or
personal injury can be occurred.

LIGHTING SYSTEMS
CAUTION : Disconnect the negative battery cable before removing or installing any electrical unit or when a tool
or equipment could easily come in contact with exposed electrical terminals. Disconnecting this cable will help
prevent personal injury and damage to the vehicle. The ignition must also be in LOCK unless otherwise noted.
