Silverado 1500 2WD V6-4.3L (2007)
Important: Do not use the terminals in the kit in order to replace damaged SIR/SRS system terminals. Use either an SIR/SRS pigtail or a
terminated lead from the SIR Repair Kit Tray.
The tool kit J-38125 contains the following items:
*
DuraSeal splice sleeves, in order to repair the SIR/SRS wiring
*
A special crimping tool
*
A heat torch
*
An instruction manual
The DuraSeal splice sleeves have the following 2 critical features:
*
A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside.
*
A cross hatched (knurled) core crimp provides the necessary low resistance contact integrity for these sensitive, low energy circuits.
The J-38125 also serves as a generic terminal repair kit. The kit contains the following items:
*
A large sampling of common electrical terminals
*
The correct tools in order to attach the terminals to the wires
*
The correct tools in order to remove the terminals from the connectors
SIR/SRS Connector Repair (Plastic Body and Terminal Metal Pin)
The terminals in the SIR/SRS system are made with a special plating. This plating provides the necessary contact integrity for the sensitive, low energy
circuits. Use the J-38125 SIR/SRS Terminal Repair Kit for repairing SIR/SRS terminals and connectors. Do not substitute any other terminals for those
in the repair kit.
The J-38125 SIR/SRS Terminal Repair Kit contains:
*
Various terminated leads for sensing and diagnostic module (SDM) terminal replacement
*
Various connector positive assurance (CPA) locks for SIR/SRS connectors
*
Base of steering column pigtail connectors part number 12085514
*
Yellow vinyl electrical tape
Pigtail repair packs are available for SIR/SRS connectors with eight or less terminals. Only the connector body is available for connectors with more
than eight terminals. The terminated leads in the J-38125 SIR/SRS Terminal Repair Kit can be used to replace damaged terminals when replacing the
connector body.
SIR/SRS Component Wire Pigtail Repair
Important: Do not make wire, connector, or terminal repairs on components with wire pigtails.
A wire pigtail is a wire or wires attached directly to the device, not by a connector. If a wiring pigtail is damaged, you must replace the entire component,
with pigtail. The inflatable restraint steering wheel module coil is an example of a pigtail component.
SIR/SRS Wire Repair
Important: Refer to Wiring Repairs in order to determine the correct wire size for the circuit you are repairing. You must obtain this
information in order to ensure circuit integrity. See: Testing and Inspection/Component Tests and General Diagnostics
If any wire except the pigtail is damaged, repair the wire by splicing in a new section of wire of the same gage size (0.5 mm, 0.8 mm, 1.0 mm etc.). Use
the DuraSeal splice sleeves and splice crimping tool from the J-38125. Use the following wiring repair procedures in order to ensure the integrity of the
DuraSeal splice sleeves.
