Damaged or defective wires and connectors (e.g. chaffed insulation, broken connector pins, torn crimping) in airbag firing circuits, will cause the airbag light (SRS light) to illuminate, and will set fault code "resistance too high" in airbag control module.
It is acceptable to repair (replace) individual pairs of firing circuit wires by using "Airbag Repair Cable" kits, crimping connectors and insulation shrink tubing. Part numbers for the assortment of "Airbag Repair Cable" kits are listed in the BMW Electronic Parts Catalog (EPC) sections 61 12 19, and 61 12 40. A detailed repair procedure can be found in the BMW Technical Information System (TIS), Repair Instruction RA 72 12 à "Repairing airbag cables".
IMPORTANT:
-- Only one crimping connector can be fitted into a single wire of the airbag firing circuit.
-- The firing circuit wires cannot be lengthened as a result of the repair.
-- Any damage to wires or connectors (for the side airbag firing circuit) in the door wiring harness must be repaired by replacing the entire door wiring harness.
