Passive Entry Transceiver
There are 2 passive entry transceivers in a vehicle, 1 on the front headliner and the other on the rear of the headliner. The passive entry transceivers are used to locate the position of the smart key from the vehicle. The passive entry transceivers communicate with the Remote Function Actuator (RFA) through Local Interconnect Network (LIN). Each passive entry transceiver has a power supply from the Passenger Junction Box (PJB) and a ground connection. When the passive entry sequence is initiated and a smart key is detected, the passive entry transceivers calculate the distance of the smart key. Then the RFA allows the authorization of the smart key only if this distance is within permissible limits.
