Antenna, Passive Entry: Description
Vehicles equipped with the optional Passive Entry (PE) and Keyless Go (KG) systems have several Low Frequency (LF), ferrite antennas (2) located within the vehicle. Each ferrite PE antenna is contained within a molded black plastic housing with an integral connector receptacle (3) molded into one end. The connector receptacle contains terminal pins that connect the antenna to the vehicle electrical system through a twisted pair of conductors and a connector that are part of the adjacent body or instrument panel wire harness.
Each antenna housing also includes an integral mounting flange or flanges (1) which can be used to mount the unit with screws. This vehicle platform uses four PE antennas.
The antennas are each connected to the Radio Frequency Hub (RFH) on dedicated and sequentially numbered circuits. The left front or rear door antenna is connected through the antenna 1 circuits, the right front or rear door antenna is connected through the antenna 2 circuits, the rear cabin wall antenna is connected through the antenna 3 circuits, the center floor console area antenna is connected through the antenna 4 circuits.

An LF antenna unit cannot be adjusted or repaired. If ineffective or damaged, it must be replaced with a new antenna. For applications where it is used, the antenna adapter or retainer may be serviced only as a unit with the LF antenna.
