Caution: Be careful when you handle a sensor. Do not strike or jolt a sensor.
Before applying power to a sensor:
• | Remove any dirt, grease, etc. from the mounting surface. |
• | Position the sensor horizontally on the mounting surface. |
• | Point the arrow on the sensor toward the front of the vehicle. |
• | Tighten all of the sensor fasteners and sensor bracket fasteners
to the specified torque value. |
Failure to follow the correct procedure could cause air bag deployment,
personal injury, or unnecessary SRS repairs.
Removal Procedure
- Disable the SRS. Refer
to
Disabling the SRS
.
- Remove the off road skid plate, if equipped. Refer to OFF-ROAD
SKID PLATE.
- Remove the connector position assurance (CPA) from the supplemental
restraint front end discriminating sensor harness connector.
- Disconnect the supplemental restraint front end discriminating
sensor harness connector from the sensor.
- Drill out the mounting rivets.
Important: Utilize the following procedures in the event that sensor mounting holes
or fasteners are damaged to the extent that the sensor may no longer be
properly mounted.
- Remove the supplemental
restraint front end discriminating sensor from the vehicle.
- Perform the following steps in order to complete the first fastener
repair:
7.1. | Remove and discard the improperly installed rivet. |
7.2. | Reattach the sensor with new rivet. |
- Perform the following steps in order to complete the second fastener
repair:
8.1. | Remove the improperly installed rivet. |
8.2. | Enlarge the mounting holes in the lower radiator support to 9.0 mm
(0.35 in). |
8.3. | Insert and properly seat the rivnut. |
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.
8.4. | Install sensor with
screw. |
Tighten
Tighten fasteners to 8.0 N·m (71 lb in).
Installation Procedure
- Install the supplemental
restraint front end discriminating sensor to the lower radiator support surface
ensure that the arrow is pointing toward the front of the vehicle.
- Install the supplemental restraint front end discriminating sensor mounting
rivets.
- Connect the supplemental
restraint front end discriminating sensor harness connector to the sensor.
- Install the connector position assurance (CPA) to the supplemental
restraint front end discriminating sensor harness connector.
- Install the off road skid plate, if equipped. Refer to OFF-ROAD
SKID PLATE.
- Enable the SRS. Refer to
Enabling the SRS
