Non-SRS Wiring Repairs: FCA

Non-SRS Wiring Repairs: FCA

What is a non-SRS wiring repair? It is the repairing of an electrical component that is not part of the supplemental restraints system circuit (usually identified by yellow wire looms). As technology increases on vehicles, so does the number of components that utilize electricity. Many of the sensors and modules are becoming smarter and more sensitive. If the wire is too long, the wrong gauge, or spliced in the wrong location, it can cause malfunctions in the components that it’s powering. Many OEMs have different restrictions and guidelines for repairing wiring that does not control SRS components. On the other hand, there are OEMs that don’t allow wiring repairs at all, so full harness replacement is the only option. Let’s take a closer look at Fiat Chrysler Automobiles (FCA).

FCA allows repairs to wiring harnesses and some connector pigtails. FCA warns that repairs cannot be made to connector pigtails attached to modules. Per FCA, "A Mopar wiring repair kit MUST be used for the splicing operation."

The FCA subscription website has the procedure on how to properly splice a wire. This procedure should be followed any time a harness repair is being made. The document can be found under Standard Procedure in the Restraints area of the service manual.

The procedure specifies crimping the wires with a splice band, soldering the connection, and sealing the splice with sealant-lined shrink tubing. There is no limit to the number of splices in any one harness, though multiple splices should be offset from each other. The procedure is the same for both Non-SRS and SRS wiring. Again, wiring harness repairs should not be carried out unless a wiring repair kit is available.

To find wiring repair kits, go to the Mopar Connection Repair Kit website. Once on the homepage, you can either select by year and model, or you can search using harness specific information, such as a part number. Click Find Now and then select a component in the results that load below. A repair kit number will be at the top of the document you have selected.

It is important to read and follow OEM procedures to be certain what electrical wiring repairs can be carried out to help achieve a complete, safe, and quality repair.
