Bonnet Switch
The bonnet switch is a plunger operated switch installed in the engine compartment on the driver's side secondary
bulkhead. When the bonnet is closed, the bonnet presses the plunger into the switch housing and holds the switch
open. When the bonnet opens, the spring loaded plunger extends, which allows the switch to close and connect a
ground to the BCU. The switch can also be held open with the bonnet open, by pulling the switch up.
Fuel Filler Flap Actuator
The fuel filler flap actuator extends and retracts a wire reinforced plastic pin to lock and unlock the fuel filler flap. A
green manual release wire is attached to the pin to ensure the fuel filler flap can be released in the event of actuator
failure or loss of power. The end of the manual release wire is stowed in the soundproofing behind the trim panel
covering the rear fusebox.
