may only be repaired using the Wiring Harness Repair Set - VAS1978- / Wiring Harness Repair Set - VAS1978A- / Wiring Harness Repair Set - VAS1978B- . ♦ Pay attention to stickers on vehicle designating high voltage components. When performing repairs, residual voltage must Pyrotechnic Components Safety Precautions . ♦ A maximum of 2 repairs may be performed when repairing wires of airbag- and seat belt tensioner system. Repairs in‐ crease the electrical resistance in the wire and may trigger malfunctions in the system On Board Diagnostic (OBD). ♦ When repairing airbag or safety belt tensioner wiring, crimp connectors must be shrunk to prevent corrosion. ♦ Wiring harness repairs may only be performed using yellow wires. ♦ Do not wrap the repair point again into the vehicle-specific wiring harness and mark the repair point very visibly with yel‐ low insulating tape. ♦ Repairs in the area of the airbag or seat belt tensioner should be performed a maximum of 30 cm from the next connector housing. Together with the identification via yellow insulating tape, this procedure makes it possible to obtain a quick over‐ view of previously performed repairs. ♦ Wires to the deploying units (airbags) have a wire-twisting with a length of lay of 20 mm ± 5 mm in series production. This length of lay is guaranteed via the norm part numbers for wire pairs in series production and must be observed strictly for the repair lengths of twisted wires. ♦ During repair work, wires to deploying units (airbags) must have the same length. When twisting together wires -1- and -2-, length of lay of A = 20 mm ± 5 mm must be strictly ob‐ served. ♦ While doing this, no section of the wire also in area of crimp connectors -arrow-, may be greater than B = 100 mm without twisting of the wires. 2.3.3 CAN Bus Lines Repair Information ♦ Unshielded two-strand wiring -1- and -2- with a cross section of 0.35 mm 2 and/or 0.5 mm 2 can be used as CAN bus wiring. ♦ The color coding of CAN bus lines can be found in the following table: Powertrain CAN high wire Orange/black Comfort CAN high wire Orange/green Infotainment CAN high wire Orange/violet CAN low wire (all) Orange/brown Beetle 2012 ➤ , Golf 2015 ➤ , Golf Variant 2007 ➤ , Golf Variant 2010 ➤ ... 100 |
