SIR/SRS WIRING REPAIRS
TOOLS REQUIRED
J-38125 Terminal Repair Kit
The Supplemental Inflatable Restraint (SIR) System/Supplemental Restraint System (SRS) requires special wiring repair procedures due to the
sensitive nature of the circuitry. Follow the specific procedures and instructions when working with the SIR/SRS, and the wiring components, such as
connectors and terminals.
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.
