Wiring Harness: Service Precautions
Safety Precautions For Repairing Wiring And Plug Connectors
CAUTION:
-
Disconnect the battery Ground strap before working on the electrical system.
-
Before starting a repair, it is important to identify the cause of damage (e.g. sharp edges on body panels, malfunctioning electrical
components, corrosion, etc.).
-
Repairs may not be performed on wiring associated with the airbag system or on shielded leads (such as wiring for speed senders or
knock sensors).
-
Only use yellow wires for repairs to wiring harnesses.
-
A yellow wire or a section of wiring wrapped with yellow insulating tape always indicates a previous repair.
-
Check the function of the components or system affected after every repair; if necessary, check DTC memory and reset systems to the
basic setting.
