Harness failure

● Damage to the wiring harness due to malfunction of electrical equipment

When electrical equipment is overloaded, short-circuited, grounded, etc., it may cause damage to the wiring harness.

● Human failure

When assembling or repairing auto parts, the metal object crushes the electric wire bundle, causing the electric wire bundle insulation layer to rupture; the positive and negative electric wires of the battery are reversed; when the maintenance circuit is faulty, the wiring harness wires and the like can be electrically connected to each other. The device is not working properly.
