If the engine is started using a booster cable when the battery is completely flat, and
the vehicle is then driven without waiting for the battery to be recharged, the engine
may misfire and it may not be possible to drive the vehicle. This is because the ABS
consumes a large amount of current when carrying out its initial checks. If this
happens, recharge the battery fully. HYDRAULIC UNIT REMOVAL AND INSTALLATION

length. Strip insulation from ends of wires. Connect wires at one end of harness
to clockspring connector stripped wires and cover connections with insulating
tape. Temporarily wrap other end of harness wires together to prevent
unexpected air bag deployment.
7. Stretch deployment harness as far away from vehicle as possible. Roll up
vehicle windows to lessen deployment noise and cover vehicle with car cover,
in case glass should shatter during deployment. Ensure area is clear of people.
Untwist deployment harness wire ends. Touch wire ends to 12 volt battery
terminals to deploy driver-side air bag module.
8. Repeat procedure for remaining air bag modules and seat belt pretensioners.
Use SRS Air Bag Adapter Harness (MB686560) for passenger-side and side
impact air bag modules. Use SRS Adapter Harness (MR991885) for seat belt
pretensioners. If any component fails to deploy, stay away from vehicle and
contact manufacturer for further instructions. Allow 30 minutes for air bag
modules to cool.
Off-vehicle Deployment 1. Before proceeding, see
AIR BAG SAFETY PRECAUTIONS
. Turn ignition
switch to LOCK position. Disconnect negative battery cable. Shield cable end.
Wait at least 60 seconds before continuing. Disconnect positive battery cable.
Remove battery from vehicle.
2. Fabricate a deployment harness using two wires at least 20 feet (6.1 m) in
length. Strip insulation from ends of wires. Twist together one end of wires
temporarily. Remove driver-side air bag module. See
DRIVER
-SIDE AIR
BAG MODULE & CLOCKSPRING
under REMOVAL &
INSTALLATION. Place driver-side air bag module on surface face up. Touch
vehicle body with bare hands to discharge static electricity from body. Cut
driver-side air bag module connector from pigtail leads. Strip insulation from
ends of
pigtail wires. Attach remainin
g ends of de
ployment harness to
pigtail NOTE: Driver-side and passenger-side air bag modules will be
either single-stage or dual-stage. Consult wiring
diagrams to ensure correct wires are cut and spliced
prior to deployment. See WIRING DIAGRAMS
