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 3-pin) which are intended for this purpose must be disconnected using an integrated short circuit bridge.
