Test program - electrical system Prerequisites for testing





Shop-made test cable

Material:
1 connector, part no. 026 545 82 28 (fig. 2)
1 plug, part no. 019 545 19 28 (fig. 3)
2 leads with 2.5 mm sockets from electrical connection set.
2 leads with 2.5 mm pins from electrical connection set.

Note
All connectors and plugs (red) for the squibs are designed with short circuit bridges. When disconnected the squib circuit or squib is short circuited. All work on the airbags and emergency tensioning retractors must therefore be accomplished with the ignition key removed.

Danger!
When welding disconnect and cover negative pole on batteries.
