Working On The Airbag System

When working on the airbag system (pyrotechnic components, Airbag Control Module -J234-, wiring), the ground cable must be disconnected when the ignition is switched on.

Exceptions: on vehicles with a battery in the vehicle interior, the ignition must be switched off.

• Then cover the negative terminal.
• Wait for 10 seconds after disconnecting the battery.
• The ignition must be on when connecting the battery.
• There must be no one inside the vehicle when connecting the battery.

If this is the case, make sure to stay out of the airbag deployment and belt tensioner zones.

If the ignition is not switched on after the battery is reconnected - the indicator lamps in the instrument cluster do not turn on - the ignition (key/button) may be switched on while sitting in the driver seat with the seat all the way back.
