Non-SRS Wiring Repairs: Jaguar Land Rover
I-CAR · June 17, 2022 · Jaguar, Land Rover
Summary
This article outlines Jaguar Land Rover's (JLR) guidelines for non-SRS wiring repairs, which are detailed in the vehicle-specific Workshop manual. It highlights that while localized repairs are permitted using approved procedures and tools, extensive damage requires a full harness replacement, and high-voltage (HV) or mild hybrid (MHEV) cables must always be replaced.
What to do on the job
Consult the vehicle-specific JLR Workshop manual's wiring harness repairability matrix, inspect the entire length of the damaged wire, and ensure any high-voltage (orange) or mild hybrid (light blue) harnesses are replaced rather than repaired.
How to use it
Use this document to justify harness replacement over repair when damage is extensive or when dealing with high-voltage (orange) and mild hybrid (light blue) wiring systems, as JLR strictly prohibits repairs on these circuits.
