basic theory of electricity, and know the meaning of voltage (volts), current (amps), and resistance (ohms). You should also be able to read and
understand a wiring diagram, as well as understand what happens in a circuit with an open or a shorted wire.
SIR/SRS Wiring Repairs
SIR/SRS Wiring Repairs
Special Tool
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.
NOTE: 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
NOTE: 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
NOTE: 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.
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.
