SIR/SRS Wiring Repairs

Special Tools

EL-38125-10 Splice Sleeve Crimping Tool.

For equivalent regional tools, refer to Special Tools .

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 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.

SIR/SRS Connector Repair (Plastic Body and Terminal Metal Pin)

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 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.

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. Terminated leads 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 the service information connector end views or the vehicle schematics 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 conductor except the pigtail is damaged repair the conductor by splicing a new section of conductor with the same dimensions (0,5 mm, 0,8 mm, 1,0 mm etc.). Use DuraSeal sleeves and the tool EL-38125-10 . For cable repairs, see Splice copper wires with sleeves .
