Passive Entry System

WARNING: This page is about a different car, the 2017 Jeep Cherokee. However, it is still accessible from the selected car via links, so may be relevant.

A Passive Entry Keyless Go (PEKG) system is available factory-installed equipment for this vehicle. The PEKG system allows the vehicle to be unlocked without the use of a mechanical key, as long as an authorized FOB with Integrated Key (FOBIK) is in the possession of the individual or in close proximity to the aperture of the vehicle that is to be unlocked. All other features and Customer Programmable feature settings of the power lock system and the Remote Keyless Entry (RKE) system function the same as they would on vehicles without the PEKG system option.

The PE system includes the following major components, which are described in further detail elsewhere in this service information:

Electronic Liftgate Latch Release Switch - A tactile liftgate release switch is located where you normally would find a mechanical latch mechanism.
Door Handle Switches - Each PE door outside handle (also known as a Smart handle) is equipped with three switches and an Integrated Circuit (IC). A tactile Lock switch is located on the outer horizontal surface of each door handle pull, a capacitive Unlock switch membrane is located on the inner vertical surface of the handle pull, while a Hall effect switch and an IC are concealed within the handle pull unit.
Low Frequency Antennas - The PE system includes four Low Frequency (LF) antennas, one mounted beneath the front of the center floor console, one on each rear door hardware module carrier concealed behind the inside trim panel, one in front of the left rear seat floor and one concealed behind the rear fascia at the rear of the vehicle.
Radio Frequency Hub Module - The Radio Frequency Hub Module (RFHM) (also known as the RF Hub) is the Passive Entry Keyless Go (PEKG) system control module and RF receiver located in the rear cargo area headliner. Refer to MODULE, RADIO FREQUENCY (RF HUB), DESCRIPTION .

Hard wired circuitry connects many of the PE system components to the electrical system of the vehicle. These hard wired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other, to the vehicle electrical system and to the PE system components through the use of a combination of soldered splices, splice block connectors, and many different types of wire harness terminal connectors and insulators. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin-out and location views for the various wire harness connectors, splices and grounds.
