Observe general notes for repairs on the vehicle electrical system, refer to VEHICLE ELECTRICAL SYSTEM, GENERAL REPAIR INFORMATION .
Not all wire cross-sections in the vehicle are contained in the Wiring Harness Repair Set VAS 1978/ Wiring Harness Repair Set VAS 1978A. If the required wire cross-section is not present, the next greater cross-section must be used.
Wiring harness and connector repairs to vehicle electrical system must only be performed using the Wiring Harness Repair Set VAS 1978/ Wiring Harness Repair Set VAS 1978A.
Soldering is not permissible for repairs to the vehicle electrical system.
Wiring harness repairs are only to be done using yellow wires.
Wiring harness repairs may not be performed again in the wrapping of the vehicle-specific wiring harness and are to be marked with yellow adhesive tape.
These yellow wires and every location on wiring harness wrapped in yellow insulating tape indicates a previous repair.
Crimp connections must never be repaired. Route a wire parallel to the faulty wire.
After crimping, the crimp connectors must be heat-shrunk using the Wiring Harness Repair Set - Hot Air Blower VAS 1978/14A to prevent moisture penetration.
Shielded harnesses may not be repaired. If faulty, the entire harness must be replaced.
Heat-resistant wires have been installed in the vehicle at various locations, mainly in the engine compartment. Heat-resistant wires can be recognized by their somewhat duller and softer insulation. Only heat-resistant wires may be used to repair these wires.
Always observe also the supplementary notes for repairing wiring harnesses on airbag- and seat belt tensioner systems, fiber optic cables, CAN bus lines, antenna wires and wires with cross-sections up to 0.35 mm ² .
