Caution: Be careful when you handle a sensor. Do not strike or jolt a sensor. Before applying power to a sensor:

1. Disable the SIR system. Refer to Disabling the SIR System .
2. Remove the hood closeout filler panel. Refer to Hood Close Out Filler Replacement in Body Front End.
3. Remove the connector position assurance (CPA) from the wiring harness connector to the inflatable restraint front end discriminating sensor.



4. Disconnect the wiring harness connector from the sensor.



5. Remove the mounting bolts (2) from the sensor (1).
6. Remove the sensor (1) from the hood latch support bracket (3).

1. Install the inflatable restraint front end discriminating sensor (1) to the hood latch support bracket (3).

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

2. Install the mounting bolts (2) to the sensor.

Tighten
Tighten the bolts to 10 N·m (89 lb in).




3. Connect the wiring harness connector to the sensor.



4. Install the CPA to the wiring harness connector.
5. Install the hood closeout filler panel. Refer to Hood Close Out Filler Replacement in Body Front End.
6. Enable the SIR system. Refer to Enabling the SIR System .
