Changed passenger airbag, module, clockspring and driver airbag. Is there anything else I should change or check/replace before I hook the negative battery cable back up? I don't want a big boom when I hook the power back up! I know there are sensors on the rad support, but they look OK, do they need to be changed too?
Thanks in advance

SERVICE AFTER A SUPPLEMENTAL RESTRAINT DEPLOYMENT

Any vehicle which is to be returned to use following a Supplemental Restraint System (SRS) component deployment must have the deployed restraints replaced. In addition, if the driver airbag has been deployed, the clockspring must be replaced and the steering column must be inspected. (Refer to 19 - Steering/Column - Diagnosis and Testing) . If the passenger airbag is deployed, the instrument panel trim cover must be replaced.
The seat belt tensioners are deployed by the same signal that deploys the driver and passenger airbags and must also be replaced if either front airbag has been deployed. If a side curtain airbag has been deployed, the headliner, as well as the upper A, B, and C-pillar trim on the same side of the vehicle as the deployed airbag must be replaced. These components are not intended for reuse and will be damaged or weakened as a result of a SRS component deployment, which may or may not be obvious during a visual inspection. On vehicles with an optional sunroof, the sunroof drain tubes and hoses must be closely inspected following a side curtain airbag deployment.
It is also critical that the mounting surfaces and mounting brackets for the Occupant Restraint Controller (ORC), side impact sensors, and front impact sensors be closely inspected and restored to their original conditions following any vehicle impact damage. Because the ORC and each impact sensor are used by the SRS to monitor or confirm the direction and severity of a vehicle impact, improper orientation or insecure fastening of these components may cause airbags not to deploy when required, or to deploy when not required.
There are two methods by which an airbag or seat belt tensioner may be connected to the vehicle electrical system. The first method involves a short pigtail harness and connector insulator that are integral to the airbag or tensioner unit and are replaced as a unit with the service replacement airbag or seat belt tensioner unit. The second method involves a wire harness takeout and connector insulator (squib circuits) that are connected directly to the air bag or tensioner initiator. The heat created by the initiator during an airbag or tensioner deployment will cause collateral damage to a directly connected wire harness take out and connector insulator. Therefore, these direct-connect type take outs and connector insulators must be repaired following an airbag or seat belt tensioner deployment. (Refer to 10 - Restraints - Standard Procedure) .
All other vehicle components should be closely inspected following any SRS component deployment, but are to be replaced only as required by the extent of the visible damage incurred.

STEERING COLUMN

The steering column bracket rear mounts that the studs or bolts go through on both sides of the steering column have a plastic/metal capsule designed to fracture or move when enough force to damage the steering column has occurred. There are 2 steering column mounting capsules, one on each side of the column. A collapse may occur where the tube housing may move into the rear bracket assembly OR the tube may move inside the tube housing. Typically if this type of collapse happens, the capsules should have indicated damage. However, if the any of the following steps indicate a collapse, the steering column will still need replacement.


NOTE: All illustrations within this procedure are typical; however the steering column capsules are the same in all vehicles.
<A xmlns="http://www.w3.org/1999/xhtml">
1.Grasp the steering wheel at the 9 and 3 o'clock positions, and again at the 12 and 6 o'clock positions and attempt to rock the steering wheel back and forth and up and down. If there is excessive movement or an audible clunking or grinding sound, replace the steering column (Refer to 19 - Steering/Column - Removal) .2.Remove the steering column opening cover (Refer to 23 - Body/Instrument Panel/COVER, Steering Column Opening - Removal) .3.If equipped, remove the retaining screws (1) and the steering column opening cover reinforcement (2).


<A xmlns="http://www.w3.org/1999/xhtml">
4.Visually inspect for fractures in the plastic area (1) and movement in the metal area (2) of the two capsules while pushing and pulling the steering wheel up and down, and left and right.5.If capsules are fractured or have moved, replace the steering column (Refer to 19 - Steering/Column - Removal) .


<A xmlns="http://www.w3.org/1999/xhtml">
6.Loosen the steering column retaining bolts (or nuts) (2, 5) several turns but do not remove. Remove only one of the rear retaining bolts (or nuts) (2). Verify that the capsule has movement, but it should not slide out of the bracket assembly. If the capsule does come out of the bracket assembly, replace the steering column (Refer to 19 - Steering/Column - Removal) .7.Install the previously removed bolt (or nut) (2) several turns, and remove the opposite one (2) and check that capsule in the same way. If the capsule does come out of the bracket assembly, replace the steering column (Refer to 19 - Steering/Column - Removal) .8.Install the steering column retaining bolts (or nuts) (2, 5) and tighten to 27 N·m (20 ft. lbs.).


<A xmlns="http://www.w3.org/1999/xhtml">
9.Measure the distance from the brake switch mounting bracket (4) to the flat of the rear mounting bracket (3). If less than 144 mm (5.6875 in. or 5 -11/16 in.), replace the steering column (Refer to 19 - Steering/Column - Removal) .10.If the steering column passes all tests and measurements above, the steering column is not collapsed and should not need to be replaced.
SUPPLEMENTAL RESTRAINT SYSTEM WIRING REPAIRS

It is important when repairing any Supplemental Restraint System (SRS) electrical circuits to use the recommended splicing kit and procedure. For applicable and available MOPAR wiring repair kits, please visit the MOPAR Connector Web Site at the following address on the internet: (http://dto.vftis.com/mopar/disclaimer.asp).
This recommended procedure involves crimping the wires together with a splice band, soldering the crimped connection and, finally, sealing and protecting the repair. The crimp and solder ensure a strong mechanical bond that will always pass a pull test while also maintaining the conductivity and current carrying capacity of the circuit. The adhesive sealant and heat shrink tubing ensures the splice repair will perform as well or better than the original wire and be safe from potential corrosion or short circuits.
There is no limit to the number of splice repairs that can be made in one harness using this procedure. However, as has been past practice, multiple adjacent splices should be offset from each other. This wiring splice repair procedure is approved for harness side repairs only. Repairs and splices to pigtail wires on SRS components such as airbag units, seat belt tensioner units or clocksprings are not approved or recommended.


REPAIR PROCEDURE

CAUTION: If additional wire is needed when making a splice repair to any wire, it is important that the same or next larger size wire gauge be used. Refer to the appropriate wiring diagram for the original wire gauge size.

<A xmlns="http://www.w3.org/1999/xhtml">
1.Remove 13 millimeters (0.50 inch) of insulation from each wire that needs to be spliced.2.Place a piece of adhesive sealant-lined heat shrink tubing (Part Number 0477Torque Wrench or equivalent) over the wire on one side of the splice. Be certain the length of tubing will be sufficient to cover and seal the entire repair area.3.Place the strands of the wires being spliced so that they are overlapping each other within the splice band (1).


<A xmlns="http://www.w3.org/1999/xhtml">
4.Using a crimping tool (1) (MOPAR Part Number 05019912AA, Miller Special Tool Number Crimper, Wire/Terminal or equivalent) crimp the splice band and wires together securely.


<A xmlns="http://www.w3.org/1999/xhtml">

CAUTION: Never use acid core solder for electrical wiring repairs.
5.Using rosin core type solder (1) only and a suitable soldering iron (3), solder the wire and splice band connection (2) together.


<A xmlns="http://www.w3.org/1999/xhtml">
6.Center the heat shrink tubing (2) over the splice joint repair and heat using a suitable heat gun. Heat the joint until the tubing is tightly sealed and sealant (1) begins to ooze out of both ends of the tubing.

Thanks Remerson you are a savior. I replace the passenger airbag connectors like above, by splicing and soldering them with the supplied parts in the "kits". I also replaced both front seatbelts. Front impact sensors look brand new also. I hooked up the negative terminal and no boom! And the airbag light is out on the dash too! So I guess I must have done it correct. The truck is now at the garage getting the 2 front fenders, hood and upper bumper cover painted. I can't wait to get this thing on the road to try her out!
Thanks again
