General Notes For Repairing Wiring Harnesses and Connectors

• Observe general notes for repairs on the vehicle electrical system. Refer to=> [ General Notes on Repairs on Vehicle Electrical System ] General Notes on Repairs on Vehicle Electrical System.

• The Wiring harness repair set (VAS 1978 B) does not contain all the wire cross-sections in the vehicle. If the required wire cross-section is not present, the next greater cross-section must be used.

• For repairs on the vehicle electrical system, soldering is not permitted.

• Do not repair crimp connectors. If necessary, lay a wire parallel to the faulty wire.

• After crimping, crimp connections must be heat-shrunk using the hot air blower to prevent moisture penetration.

• Shielded wires such as for speed sensors and knock sensors may not be repaired. If faulty, the entire harness must be replaced.

• Exclusive use is to be made of yellow wires for wiring harness repairs.

• Wiring harness repairs should not be made again in the wrapping on the vehicle-specific wiring harness.

• Mark repaired areas using yellow adhesive tape.

• Yellow wires and areas in the wiring harness wrapped with yellow adhesive tape mark a previously performed repair.

• Perform a function test after each repair. If necessary, check DTC memory, erase and/or bring systems into basic setting.
