Keyless Entry Receiver: Description and Operation

RF RECEIVER (WHERE FITTED)

The RF receiver converts signals from the RF remote handset into digital messages and transmits them to the GEM (generic electronic module). The RF receiver is installed at the rear of the roof, above the roof liner, to the left of the vehicle centerline.

Operation of the RF receiver is powered by a permanent battery feed from the AJB. RF remote handset signals are received by the rear window antenna and passed to the RF receiver via the antenna amplifier.

INFRARED RECEIVER (WHERE FITTED)

The infrared receiver converts the signals from the infrared remote handset into digital messages and transmits them to the GEM (generic electronic module). The infrared receiver is integrated into the interior rear view mirror, with the receiving diodes installed in the circular knob on the underside of the mirror. Operation of the receiver is powered by a permanent battery feed from the CJB (central junction box).
