Keyless Entry: Description and Operation

The Remote Keyless Entry System employs the Power Door Lock Relay, the Left and Right Door Lock Motors, the Keyless Entry Module and Keyless Entry Transmitter.

The Keyless Entry Module receives battery voltage at all times from the ROOM Fuse. This module receives an "ignition on" signal from the METER Fuse. All remote functions are disabled with the Ignition Switch on.

LOCK/UNLOCK DOOR FEATURE

Pressing the door unlock or lock button on the transmitter causes the Keyless Entry Module to apply a voltage signal to the Power Door Lock Relay via circuit 335 (GN/BK). The doors either lock or unlock depending on the signal from the module. Refer to Power Door Locks for a complete circuit operation of the power door locks. If the command is an unlock command, circuit 904 (Y/R) is grounded, disarming the theft deterrent system.

ILLUMINATED ENTRY FEATURE

The Illuminated Entry Feature is activated when either the Transmitter Door Unlock Button or the Panic Button is pressed. Circuit 333 (GN) is grounded by the Keyless Entry Module, turning on the Courtesy Lamps.

PANIC ALARM

When the panic alarm button on the transmitter is pressed, circuit 323 (GN/O) is grounded intermittently, causing the Horns to beep. At the same time, circuit 115 (GN/R) to the Flasher Module is grounded by the Keyless Entry Module, causing the hazard lamps to flash as if the Hazard Switch was set.

TRANSMITTER PROGRAMMING

To program the Keyless Entry Module to Keyless Entry Transmitter(s), the Program Connector must be jumpered. With the Ignition in "RUN", pressing a key on the transmitter to be programmed programs the Keyless Entry Module to accept that transmitter's signals.
