Vehicle Theft Security Hood Ajar Switch - Description

DESCRIPTION

LATCH MOUNTED





There are two types of hood ajar switches used on this vehicle. This information covers the hood latch mounted hood ajar switch (1) that is standard equipment on all vehicles. A stand alone switch is also used on some vehicles in addition to the latch mounted switch, but is discussed elsewhere in this service information. This switch is integrated into the hood latch assembly and is a normally open, single pole, spring-loaded plunger actuated switch. The input of this switch may be used for the Vehicle Theft Alarm (VTA) system as well as for the optional remote start system. The switch is connected to the vehicle electrical system through a dedicated take out and connector of the headlamp and dash wire harness.

The latch mounted hood ajar switch can not be adjusted or repaired. If damaged or ineffective this switch type must be replaced as a unit with the hood latch assembly.

STAND ALONE





There are two types of hood ajar switches used on this vehicle. This information covers the stand alone hood ajar switch (1) that is optional equipment on some vehicles. A latch mounted hood ajar switch is standard on all vehicles, but is discussed elsewhere in this service information. The stand alone switch has a molded plastic switch body (5) with 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 and connector of the headlamp and dash wire harness. Two integral latches (2) lock the switch into a keyed mounting hole in the switch mounting bracket. The mounting bracket is secured to the upper radiator cross member. 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 input of this switch is used exclusively for the start-stop system, which is optional equipment with certain optional engines.

Once a stand alone hood ajar switch is installed it cannot be readjusted or repaired. If the switch is damaged, ineffective or requires readjustment, it must be replaced with a new unit. The hood ajar switch striker is not intended for reuse. If the striker is removed from the hood inner reinforcement for any reason, it must be replaced with a new unit.
