QuestionWhere are the sensors and module located
AnswerMODULE
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, 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 Occupant Restraint Controller (ORC), as it can damage the impact sensor or affect its calibration. The ORC contains the impact sensor, which enables the system to deploy the Supplemental Restraint System (SRS) compionents. If an ORC is accidentally dropped during service, the module must be scrapped and replaced with a new unit. Failure to observe this warning could result in accidental, incomplete, or improper SRS component deployment.
1. Disconnect and isolate the battery negative cable. Wait two minutes for the system capacitor to discharge before further service.
2. Remove the protective cover from the Occupant Restraint Controller (ORC) (1). (Refer to 8 - ELECTRICAL/RESTRAINTS/ORC COVER - REMOVAL) .
3. Unlatch and disconnect the two wire harness connectors (3) for the ORC from the ORC connector receptacles (2 and 4) located on the forward facing side of the module. To disconnect the wire harness connectors from the ORC, depress the release tab and lift the lever arm on each connector.
4. Remove the three nuts (2) that secure the ORC (1) to the studs on the ORC mounting bracket (3) on the floor panel transmission tunnel.
5. Remove the ORC from the floor panel transmission tunnel
FRONT
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, 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.
1. Disconnect and isolate the battery negative cable. Wait two minutes for the system capacitor to discharge before further service.
2. Remove the screw (4) that secures the right or left front impact sensor (3) to the back of the right or left end of the lower radiator crossmember (1).
3. Disconnect the headlamp and dash wire harness connector (2) from the sensor connector receptacle.
4. Remove the right or left front impact sensor from the engine compartment.
SIDE - MEGA CAB
Adjust the front seat to its most forward position for easiest access to the B-pillar trim.
2. Disconnect and isolate the battery negative cable. Wait two minutes for the system capacitor to discharge before further service.
3. Remove the nut (3) that secures the stud of the side impact sensor (4) to the inner B-pillar (2).
4. Reach through the large hole above the retractor mounting hole in the inner B-pillar to access the side impact sensor and disengage the anti-rotation pin and mounting stud from the holes in the inner B-pillar.
5. Pull the side impact sensor out through the large hole in the B-pillar far enough to access and disconnect the body wire harness connector (1) from the sensor connector receptacle.
6. Remove the side impact sensor from the B-pillar
SIDE - QUAD CAB
Adjust the front seat to its most forward position for easiest access to the B-pillar trim.
2. Disconnect and isolate the battery negative cable. Wait two minutes for the system capacitor to discharge before further service.
3. Remove the nut (3) that secures the stud of the side impact sensor (2) to the inner B-pillar (1).
4. Reach through the large hole above the retractor mounting hole in the inner B-pillar to access the side impact sensor and disengage the anti-rotation pin and mounting stud from the holes in the inner B-pillar.
5. Pull the side impact sensor out through the large hole in the B-pillar far enough to access and disconnect the body wire harness connector (4) from the sensor connector receptacle.
6. Remove the side impact sensor from the B-pillar
SIDE - STANDARD CAB
Adjust the driver or passenger side front seat to its most forward position for easiest access to the B-pillar trim.
2. Disconnect and isolate the battery negative cable. Wait two minutes for the system capacitor to discharge before further service.
3. Remove the front outboard seat belt and retractor from the inside of the B-pillar. (Refer to 8 - ELECTRICAL/RESTRAINTS/FRONT OUTBOARD SEAT BELT AND RETRACTOR - REMOVAL - STANDARD CAB) .
4. Remove the nut (4) that secures the stud of the side impact sensor (1) to the inner B-pillar.
5. Reach through the retractor mounting hole (3) in the inner B-pillar to access the side impact sensor and disengage the anti-rotation pin and mounting stud from the holes in the inner B-pillar.
6. Pull the side impact sensor out of the B-pillar far enough to access and disconnect the body wire harness connector (2) from the sensor connector receptacle.
7. Remove the sensor from the B-pillar
