Dodge Nitro. Manual — part 239

1. Disconnect and isolate the battery negative cable. Wait two minutes for the system capacitor to discharge

before further service.

2. Service access for the right front impact sensor is accomplished by removing the air filter housing from

the engine compartment. Service access for the left front impact sensor is accomplished by raising and
supporting the vehicle, then removing the access plug from the front of the left front wheel house liner.

3. Remove the nut (3) that secures the front impact sensor (5) to the stud (6) on the back (engine

compartment side) of the front end module carrier below and inboard of the front lamp unit park/turn
signal bulb socket (1).

4. Disconnect one end of the jumper wire harness (4) from the right or left front impact sensor connector

receptacle or from the body wire harness (2).

5. Remove the right or left front impact sensor from the engine compartment.

INSTALLATION

FRONT IMPACT SENSOR

WARNING:

To avoid serious or fatal injury on vehicles equipped with airbags, disable
the Supplemental Restraint System (SRS) before attempting any steering
wheel, steering column, airbag, Occupant Classification System (OCS),
seat belt tensioner, impact sensor, or instrument panel component
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, never strike or drop the front impact
sensor, as it can damage the impact sensor or affect its calibration. The
front impact sensor enables the system to deploy the front Supplemental
Restraint System (SRS) components. If an impact sensor is accidentally
dropped during service, the sensor must be scrapped and replaced with a
new unit. Failure to observe this warning could result in accidental,
incomplete, or improper front SRS component deployment.

NOTE:

The front and side impact sensors are interchangeable.

1. Service access for the right front impact sensor is accomplished by removing the air filter housing from

the engine compartment. Service access for the left front impact sensor is accomplished by raising and
supporting the vehicle, then removing the access plug from the front of the left front wheel house liner.

2. Position the right or left front impact sensor (5) into the engine compartment.

3. Reconnect the jumper wire harness (4) to the right or left front impact sensor connector receptacle or to

the body wire harness (2).

4. Position the sensor onto the stud (6) on the back (engine compartment side) of the front end module

carrier below and inboard of the front lamp unit park/turn signal bulb socket (1). Be certain that the anti-
rotation pin on the back of the sensor is engaged in the clearance notch of the carrier and the connector
receptacle is pointed straight downward.

5. Install and tighten the nut (3) that secures the sensor to the stud on the back of the carrier. Tighten the nut

to 8 N.m (71 in. lbs.).

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.

SIDE IMPACT SENSOR - C-PILLAR

WARNING:

To avoid serious or fatal injury on vehicles equipped with airbags, disable
the Supplemental Restraint System (SRS) before attempting any steering
wheel, steering column, airbag, Occupant Classification System (OCS),
seat belt tensioner, impact sensor, or instrument panel component
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.

1. Reconnect the body wire harness connector (3) to the side impact sensor (2) connector receptacle.

2. Position the impact sensor onto the weld stud on the inner C-pillar (4). Be certain that the anti-rotation pin

on the back of the sensor is engaged in the clearance hole of the C-pillar.

3. Install and tighten the nut (1) that secures the sensor to the weld stud on the inner C-pillar. Tighten the nut

to 7 N.m (62 in. lbs.).

4. Reinstall the trim onto the inside of the lower C-pillar. Refer to INSTALLATION .

5. 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.

SIDE IMPACT SENSOR - B-PILLAR

WARNING:

To avoid serious or fatal injury, never strike or drop the side impact
sensor, as it can damage the impact sensor or affect its calibration. The
side impact sensor enables the system to deploy the side Supplemental
Restraint System (SRS) components. If an impact sensor is accidentally
dropped during service, the sensor must be scrapped and replaced with a
new unit. Failure to observe this warning could result in accidental,
incomplete, or improper side SRS component deployment.

NOTE:

The front and side impact sensors are interchangeable.

WARNING:

To avoid serious or fatal injury on vehicles equipped with airbags, disable
the Supplemental Restraint System (SRS) before attempting any steering
wheel, steering column, airbag, Occupant Classification System (OCS),
seat belt tensioner, impact sensor, or instrument panel component
diagnosis or service. Disconnect and isolate the battery negative (ground)
cable, then wait two minutes for the system capacitor to discharge before

1. Reconnect the body wire harness connector (4) to the side impact sensor (3) connector receptacle.

2. Position the sensor onto the weld stud on the inner B-pillar (1). Be certain that the anti-rotation pin on the

back of the sensor is engaged in the clearance hole of the B-pillar.

3. Install and tighten the nut (2) that secures the sensor to the weld stud on the inner B-pillar. Tighten the nut

to 7 N.m (62 in. lbs.).
