The remote keyless entry and anti-theft system can perform the following functions:

The remote keyless entry anti-theft system consists of the following components:

The hand-held transmitter locks and unlocks the vehicle doors by sending radio waves to the ISU in the vehicle. The effective range of the transmitter varies between 5 and 10 meters (approximately 16 to 32 feet), depending on whether or not objects such as other vehicles are blocking the path of the radio waves. The transmitter has a LOCK button and an UNLOCK button which function only when the ignition is OFF and all openings (doors, engine hood, rear deck lid) are closed. Pressing the UNLOCK button has the following effects:

Pressing the LOCK button has the following effects:

1. The doors are locked.
2. The turn signals flash once.
3. The module is armed.

The transmitter has a replaceable battery. The battery is designed to last at least three years before replacement is necessary.

SECURITY INDICATOR There is a SECURITY indicator on the instrument cluster. After the LOCK button of the transmitter is pressed, the module/receiver is placed in the armed mode, and the SECURITY indicator flashes. The SECURITY indicator turns ON for 0.1 second and OFF for 0.7 second, and it flashes at that frequency until the module/receiver is disarmed.

The anti-theft function is armed if the transmitter sends the LOCK message to the ISU. when the ignition is OFF. If the hood, the door, or the rear deck lid is opened, the hood open, the door contract, or the rear deck lid open switch will change its input to the ISU, and the alarm will be activated unless either of the following conditions has occurred:

The alarm will also be activated if the ignition input is changed to battery voltage before either of the following conditions occurs:

The alarm will also be activated if the anti-theft function has been armed and the ultrasonic sensor (optional) detects movement within the vehicle before the front door or rear deck lid tamper switches have indicated key operation.

The remote keyless entry system is armed when the LOCK message is received from the transmitter when the ignition is OFF. When the system is armed, it will activate the siren and flash the turn signals for 28 seconds if any of the following conditions occurs:

The siren is disarmed after it begins to sound an alarm if any of the following conditions occurs:

The remote keyless entry system assists the driver in locating the vehicle. When the vehicle is unlocked with the remote control, the turn signals flash twice to indicate the location of the vehicle. The duration of the flashes and the length of time between flashes is used to indicate certain vehicle conditions. .

The remote keyless entry system has an automatic locking feature. If the doors are unlocked with the remote transmitter while the control module/receiver is armed, the doors are automatically re-locked after 30 seconds unless any of the following events occurs:

The ISU is installed on the left side of the steering column in side the instrument panel. ISU processes signals from the remote transmitter and the intrusion sensors, and it activates the alarm if an invasion is detected.

The ISU also has a self-diagnostic functions which will display trouble codes. In order to display trouble coeds, a scan tool must be connected to the Data Link Connector( DLC).

The ISU will not communicate with transmitters from other vehicles because there are over four billion possible electronic password combinations. The ISU has an attached antenna to detect signals from the transmitter.

When the UNLOCK button on the remote transmitter is pressed, the ISU will flash the parking lights to indicate information about the remote keyless entry and anti-theft system.

Normal Condition: If there has not been an intrusion and no fault has been detected, the ISU will signal a normal condition when the UNLOCK button is pressed. The parking lights will flash twice for 1 second with a 1.0-second pause between flashes.

Alarm Indication: If there has been an intrusion since the last time the LOCK button was pressed, the ISU will signal that there has been an intrusion when the UNLOCK button is pressed. The parking lights will flash twice for 0.5-second, and there will be a 1.5-second pause between flashes.

Alarm and fault information in the ISU will be erased the next the ISU enters the armed condition after receiving a LOCK message from the transmitter.
