SUBJECT:
SUPPLEMENTAL INFLATABLE RESTRAINT SYSTEM WIRING REPAIR PROCEDURES
MODELS AFFECTED:
1990 RIVIERA/REATTA
Special wiring repair procedures have been developed for use on the Supplemental Inflatable Restraint (SIR) system due to the sensitive nature of the
circuitry. The instructions in this bulletin are to be followed whenever servicing the SIR system wiring.
TERMINAL REPAIR KIT J-38125
Essential tool kit J-38125 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.
Two 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 (knurled) core crimp to provide necessary contact integritv for the sensitive, low energy circuits.
Tool kit J-38125 also serves as a generic terminal repair kit. The kit contains a large sampling of common GM electrical terminals and the correct tools
to apply them to wires and remove them from connectors. The terminals in the kit are not to be used to replace damaged SIR system terminals unless
otherwise indicated by the terminal package. Specifically, the DERM/resistor terminal repair assembly pack, is included in J-38125 for SIR use.
SIR CONNECTOR (PLASTIC BODY) AND TERMINAL (METAL PIN) REPAIR
If any connector or terminal in the SIR wire harness (except pigtails) is damaged, the component should be repaired using one of the connector repair
assembly packs. These kits include an instruction sheet and the sealed splices which will be necessary to splice the new wires, connector, and terminals
to the harness. Crimping tool J-38125-8 (the tool which is color keyed to match the splices) from terminal repair kit J-38125 must be used to apply these
splices.
The terminals in the SIR system are made of a special metal to provide necessary contact integrity for the sensitive low energy circuits. These terminals
are only available in the connector repair assembly packs and no other terminal should be substituted.
If individual terminals are damaged on the DERM or resistor module, they should be repaired 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 Connector Repair
Assembly Pack.
SIR WIRE PIGTAIL REPAIR
If the wiring pigtail (wire attached directly to the device, not by a connector) of any SIR system component (Sensor, Coil Assembly, or Inflator Module)
is damaged, the entire component (with pigtail) should be replaced. Absolutely no wire, connector, or terminal repair is to be attempted on the Dual
Sensor, the Forward Discriminating Sensor, the Inflator Module, or the SIR Coil Assembly.
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 (.5, .8, 1.0, etc.). The
sealed splices and crimping tool from terminal repair kit J-38125 must be used for these splices. Carefully follow the instructions included in the kit for
proper sealed splice application.
SIR SYSTEM WIRE SPLICE REPAIR
If any of the original equipment splices (S201, etc., three wires or more) in the SIR system wiring are damaged, they should be repaired by applying a
new splice clip (not sealed) from terminal kit J-38125. Carefully follow the instructions included in the kit for proper splice clip application. Cloth duct
tape may be substituted for splice tape if necessary.
