Switch, Door Handle: Description
Vehicles equipped with the optional Passive Entry (PE) system have unique outside door handles that incorporate three switches and a logic circuit. These unique PE door handles are sometimes referred to as smart handles. The handle itself is very similar in appearance to those used in conventional non-PE applications, consisting primarily of a pull (4) and a base.
The PE door handles can be readily identified by a tactile, resistive membrane lock switch (3) located on the outward facing horizontal surface at the top of the pull, and by a capacitive sensor or switch membrane patch on the inside surface (2) of the pull. A third, Hall-effect type switch as well as an Integrated Circuit (IC) chip are concealed within the pull.
The mechanical functions and mounting provisions of the PE handle are identical to those of a conventional outside door handle. However, an integral connector receptacle (2) is located at the back of the handle base where it is concealed within the door interior. The PE handle is connected to the vehicle electrical system through a dedicated take out and connector of the PE door jumper wire harness.
The individual switches of the PE outside front door handles cannot be adjusted or repaired. If any one of the switches, the IC or any of the mechanical handle components is damaged or ineffective, the entire handle unit must be replaced. Refer to HANDLE, EXTERIOR, REMOVAL .
