DESCRIPTION The hood ajar switch is a normally closed, single pole, spring-loaded plunger actuated switch. This switch has two unique versions that are used in two different applications. One switch is used only on vehicles equipped with the Vehicle Theft Alarm (VTA) system for sale in certain export markets where protection of the underhood area is required equipment. The second switch is used only on domestic vehicles equipped with an optional remote starter system. The molded plastic switch body (5) has an integral molded connector receptacle (1) on the lower end containing two terminal pins. The switch is connected to the vehicle electrical system through a dedicated take out of the engine compartment wire harness. Two integral latches (2) lock the switch into a keyed mounting hole in an a molded plastic cup-like adapter that, in turn snaps into a horizontal bracket that extends rearward from the top of the front end module carrier, to the left of center at the front of the engine compartment. The underside of the hood panel inner reinforcement actuates the switch plunger as the hood panel is closed. The switch plunger (3) extends through a mounting collar (4) and a sleeve-like retainer ring on the upper end of the switch body. The retainer ring has a one time, self-adjustment feature that is activated after the switch is installed by closing the hood. The retainer ring is also color-coded to aid in identifying the switch application. A dark brown retainer ring identifies the underhood security switch application, while a white retainer ring identifies the remote starter system application. An installed hood ajar switch cannot be readjusted or repaired. If the switch is damaged, ineffective, or requires readjustment, it must be replaced with a new unit.
