The keyless entry system incorporates a hand-held transmitter, and a remote control door lock receiver (RFA). The transmitter sends a digitally encoded radio signal to the receiver if you push a button. The following functions can be remotely controlled:

The range of the transmitter is approximately 7 meters (23 feet).

The standby (parasitic) current drain on the vehicle's battery due to the door lock receiver the remote control is approximately 2.2 milliamps. The actual amount varies slightly with temperature and battery charge.

The remote control door lock receiver grounds the interior lamps for approximately 40 seconds if the receiver receives a door unlock signal. If you turn the ignition switch to RUN within those 40 seconds, the receiver turns off the interior lamps.

If you press the transmitter's unlock button once, the driver's door unlocks. Upon receiving the signal from the transmitter, the door lock receiver activates the remote control output at connector C1, terminal A. This applies battery voltage directly to the door lock motor the left front. The motor is grounded through the automatic door lock relay.

If the receiver receives a signal from the transmitter twice within 5 seconds, the receiver activates the outputs at both connector C1, terminal A, and connector C1, terminal B. The driver's door motor is driven as described above. The unlock relay in the door lock relay assembly is energized, causing the other doors to unlock.

Pressing the lock button on the transmitter results in the receiver activating the output at connector C1, terminal R. This energizes the lock relay (within the automatic door lock relay), locking the doors. The driver's door is grounded through the receiver when locking.

In order to prevent the transmitter's signal from being recorded and retransmitted, an iterative code is incorporated into the door lock receiver remote control. Each time the transmitter is used, the receiver changes the code. The code changes according to a pre-programmed scheme. The transmitter and the receiver remain synchronized. Otherwise, the receiver will not recognize the transmitter's encoded signal.

If you activate the transmitter outside the range of the system more than a predetermined number of times, the transmitter will no longer be synchronized with the receiver. The receiver does not respond to the transmitter's signal until the transmitter and receiver are re-synchronized. Refer to Transmitter Synchronization .

The door lock receiver remote control applies battery voltage to the lid release solenoid rear compartment, if you press the lid release button rear compartment on the transmitter. The receiver cannot activate the solenoid if connector C1, terminal K, is not grounded. This terminal is grounded under the following conditions:
