SIR Wiring Repair

Special wiring repair procedures have been developed for use on the Supplemental Inflatable Restraint systems due to the sensitive nature of the circuitry.
The use of Terminal Repair Kit tool No. J-38125 or equivalent, contains special sealed splices for use in repairing SIR system wiring. A special crimping tool, heat torch and instruction manual for these splices are also included.
The critical features of the sealed splices are a special heat shrink sleeve with sealing adhesive to produce an environmentally sealed splice and a cross hatched core crimp to provide necessary contact integrity for the sensitive low energy circuits.

SIR CONNECTOR BODY & TERMINAL REPAIR
If any connector or terminal in the SIR wire harness, except pigtail, is damaged the component should be repaired using one of the connector repair assembly packs. These kits include an instruction sheet and sealed splices which will be necessary to splice the new wires, connector and terminals to the harness.
If individual terminals are damaged on the DERM or resistor module, repair using the DERM/resistor terminal repair assembly pack. If individual terminals are damaged on any other SIR connection, the entire connection should be replaced using the appropriate repair assembly pack.

SIR PIGTAIL REPAIR
If the wiring pigtail is damaged, the entire component should be replaced.

SIR WIRE REPAIR
If any wire except the pigtail is damaged, the wire should be repaired by splicing in a new section of wire of the same gauge size. The sealed splices and crimping tool from J-38125 must be used for these splices.
