Diagnosis/troubleshooting

WARNING:
Risk of injury if vehicle is driven with special tools in place (commercially available tools included).
- Never drive with special tools or commercially available tools attached in place of the airbag units.

NOTE: Never disconnect plugs which are connected directly to airbag modules and belt tensioners because these have been connected with a defined contact pressure to prevent the plug from working loose in order to prevent malfunction during the life of the vehicle. The plug connections (mostly 3pm) which are intended for this purpose must be disconnected using an integrated short circuit bridge.
