Okay to Repair
Audi
Per the Audi repair manual:
"The airbag and seat belt tensioner system can fail.
"Faulty repairs performed on airbag and seat belt tensioner system can lead to malfunction in passenger protection.
"When performing repairs on airbag and seat belt tensioner wiring harness, use only terminals, connectors and wires designated for it. Refer to the Parts Catalog."
BMW and Mini
Per BMW service information:
“Only repair those cables which show visible signs of damage. In the event of visible damage, make sure there is only one cable repair in effect after the repair work. If no visible damage can be identified, the entire cable must be replaced. When carrying out repairs to the airbag wiring harness, you must use the spare parts offered in the Electronic Parts Catalogue (EPC).”
Chevy, Cadillac, Buick and GMC
Per the General Motors (GM) service information Document ID 325229 – SIR/SRS Wiring Repairs:
“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.”
Fiat / Chrysler / Dodge / Jeep / RAM / Alfa Romeo
Per FCA/Stellantis service information:
FCA/Stellantis permits supplemental restraints system (SRS) wiring repairs only if a Mopar® wiring repair kit is available, and all repairs must follow the OEM-approved procedures detailed in vehicle-specific service manuals. These procedures, found under Service Information ➤ Restraints ➤ Standard Procedures ➤ SRS Wiring Repairs, are limited to harness-side repairs and require crimping wires with a splice band, soldering the connection, and sealing it with adhesive-lined shrink tubing (e.g., part number 04778570). This ensures a strong, corrosion-resistant repair that meets or exceeds the original wiring performance.
Always consult OEM procedures to ensure safe, high-quality repairs. For repair kits, visit the Mopar Connection Repair Kit website, and for parts inspection and replacement after deployment, refer to the OEM Restraints System Part Replacement Search. Additional service information is available at stellantisiop.com.

- A stand-alone harness, do not repair them. Replace the restraints harness unless directed to repair the circuit by a TSB or other Ford publication.
- The main vehicle wiring harnesses, they should be repaired using the solder and heat-shrink repair procedures in this TSB. The General Wire Terminal Repair Kit contains gold-plated terminated pigtails (with white insulation) and dual-wall heat-shrink tubing to perform these repairs. Loaded wiring pigtail kits with goldplated terminals are also available in the parts catalog.”
