Disconnecting the fuel delivery unit with crash signal
Operation
The vehicles with airbag are equipped with a crash signal fuel shut-off system. If the airbag units are triggered while driving, the fuel pump relay -J17- opens and the fuel delivery unit is deactivated. This also enhances the starting behaviour of the engine. When the door is opened, the fuel pump is operated for about 2 seconds so that pressure is built up in the fuel system.
