In all types of accidents regardless of “Air Bag”
deployment, visually inspect all of the following
components and replace as required: 

–  Driver air bag assembly 

–  Passenger air bag assembly

The SRS control unit should always be checked
according to “SRS Control Unit Replacement 
Guidelines.” 

CAUTION: Refer to “SRS control unit Replacement
Guidelines” below for important information on
SRS control unit replacement in both deployment
and non–deployment crashes. 

Inspect the SRS coil assembly wiring and the steering 
wheel for any sign of scorching, melting, or damage
due to excessive heat. If the coil assembly wire or
steering wheel is damaged, replace them.  The
steering column and wheel must be dimensionally
checked to determine if they are damaged.  Refer to
“steering wheel” in this manual. 

Never use SRS parts from another vehicle. This does
not include remanufactured parts purchased from an
authorized ISUZU/GM Retailer; they may be used for
SRS repairs. 

Do not attempt to repair the SRS control unit, the SRS
harness, the SRS coil assembly, the air bag assembly,
the steering wheel, or the steering column.  Service of
these items is replacement only. Verify replacement
part numbers. 

CAUTION: Proper operation of the SRS control
unit and the supplemental restraint system (SRS)
requires that any repairs to the vehicle structure
return it to its original production configuration.

used for the supplemental restraint system-air bag 
circuit. When removing the cable harness, do not 
pull the cables otherwise cable disconnection may 
occur. When connecting the SRS connector, insert
the connector completely. Imperfect locking may 
cause malfunction of the SRS circuit.  

Removal 

To remove the connector, hold the cover insulator (1) 
and pull it. The cover insulator slides and the lock will
