AIR BAG WIRE HARNESS AND CONNECTORS
Air bag wire harness can be identified easily as it is covered with a
yellow protection tube. Be very careful when handling it.

When an open in air bag wire harness, damaged wire harness,
connector or terminal is found, replace wire harness, connectors
and terminals as an assembly.

When installing it, be careful so that the air bag wire harness is not
caught or does not interfere with other parts.

Make sure all air bag system grounding points are clean and
grounds are securely fastened for optimum metal-to-metal con-
tact. Poor grounding can cause intermittent problems that are dif-
ficult to diagnose.
DISPOSAL
Do not dispose of the live (undeployed) air bag (inflator) modules
and the live (inactivated) seat belt pretensioners. When disposal is
necessary, be sure to deploy the air bag according to deployment
procedure described under ªAir Bag (Inflator) Modules Disposalº
and to activate the pretensioner according to activation procedure
described under ªSeat Belt Pretensioners Disposalº.
WARNING:
Failure to follow proper air bag (inflator) module and seat
belt pretensioner disposal procedures can result in air bag
deployment and pretensioner activation which could cause
personal injury. Undeployed air bag (inflator) module and
inactivated seat belt pretensioner must not be disposed of
through normal refuse channels.
The undeployed air bag (inflator) module and inactivated
seat belt pretensioner contain substances that can cause
severe illness or personal injury if the sealed container is
damaged during disposal.
