1. Position the driver airbag (1) close enough to the steering wheel to reconnect the electrical connections 

diagnosis or service. Disconnect and isolate the battery negative (ground) 
cable, then wait two minutes for the system capacitor to discharge before 
performing further diagnosis or service. This is the only sure way to 
disable the SRS. Failure to take the proper precautions could result in 
accidental airbag deployment.

WARNING:

To avoid serious or fatal injury, use extreme care to prevent any foreign 
material from entering the driver airbag, or becoming entrapped between 
the driver airbag cushion and the driver airbag trim cover. Failure to 
observe this warning could result in occupant injuries upon airbag 
deployment.

WARNING:

To avoid serious or fatal injury, the driver airbag trim cover must never be 
painted. Replacement airbags are serviced with trim covers in the original 
colors. Paint may change the way in which the material of the trim cover 
responds to an airbag deployment. Failure to observe this warning could 
result in occupant injuries upon airbag deployment.

NOTE:

The following procedure is for replacement of an ineffective or damaged driver 
airbag. If the airbag is ineffective or damaged, but not deployed, review the 
recommended procedures for handling non-deployed supplemental restraints. 
See HANDLING NON-DEPLOYED SUPPLEMENTAL RESTRAINTS. If the driver 
airbag has been deployed, review the recommended procedures for service 
after a supplemental restraint deployment before removing the airbag from the 
vehicle.

(4) to the back of the airbag housing. 

2. When installing the driver airbag, reconnect the two clockspring driver airbag pigtail wire connectors to 

the airbag inflator (5) connector receptacles by pressing straight in on the connectors, then push the locks 
straight into the connectors. Be certain to engage each keyed and color-coded connector to the matching 
connector receptacle.  

3. Carefully position the driver airbag into the steering wheel hub. Be certain that the clockspring pigtail 

wires are not pinched between the driver airbag and the horn switch or the steering wheel armature.  

4. Engage the lower airbag snap retainer wire loop (3) onto the lower hook of the steering wheel armature. 

The lower snap retainer wire loop has a distinctive V-shape and must always be installed onto the six 
o'clock hook of the steering wheel armature.

5. Roll the driver airbag (3) upwards and press firmly and evenly over the two upper snap retainer wire loop 

(4) locations simultaneously until they snap into place over the two upper hooks (2) of the steering wheel 
armature.  

6. Do not reconnect the battery negative cable at this time. The Supplemental Restraint System (SRS) 

verification test procedure should be performed following service of any SRS component. See 
VERIFICATION TEST - SUPPLEMENTAL RESTRAINT SYSTEM.  

IMPACT SENSOR 

DESCRIPTION 

FRONT IMPACT SENSOR

Two front impact sensors (1) are used on this vehicle, one each for the left and right sides of the vehicle. These 
sensors are mounted remotely from the impact sensor that is internal to the Occupant Restraint Controller 
(ORC). Each front sensor is secured with a nut to a stud on the back of the front end module carrier on either 
side of the cooling module, below and inboard of the front park/turn signal lamp socket within the engine 
compartment. The sensor housing has an integral connector receptacle (4), an integral anti-rotation pin (3), and 
an integral mounting hole (2) with a metal sleeve to provide crush protection. 

The right and left front impact sensors are identical in construction and calibration. A cavity in the center of the 
molded black plastic impact sensor housing contains the electronic circuitry of the sensor which includes an 
electronic communication chip and an electronic impact sensor. A nylon cover is laser-welded over the cavity to 
seal and protect the internal electronic circuitry and components. The front impact sensors are each connected to 
the vehicle electrical system through a short jumper wire harness to a dedicated take out and connector of the 
body wire harness. 

The impact sensors cannot be repaired or adjusted and, if damaged or ineffective, they must be replaced.

SIDE IMPACT SENSOR

Two side impact sensors (1) are used on this vehicle when it is equipped with the side curtain airbags, two each 
for the left and right sides of the vehicle. These sensors are mounted remotely from the impact sensor that is 
internal to the Occupant Restraint Controller (ORC). Each side sensor is secured with a nut to a stud on the 
inner right or left B-pillar above the front seat belt retractor, or to a stud on the right or left inner C-pillar just 
forward of the second row outboard seat belt retractor within the passenger compartment. The sensor housing 
has an integral connector receptacle (4), an integral anti-rotation pin (3), and an integral mounting hole (2) with 
a metal sleeve to provide crush protection. 

The right and left side impact sensors are identical in construction and calibration. A cavity in the center of the 
molded black plastic impact sensor housing contains the electronic circuitry of the sensor which includes an 
electronic communication chip and an electronic impact sensor. A nylon cover is laser-welded over the cavity to 
seal and protect the internal electronic circuitry and components. The side impact sensors are each connected to 
the vehicle electrical system through a dedicated take out and connector of the body wire harness.
