Antitheft Relay: Description and Operation
STARTER INTERRUPT RELAY/HEADLIGHT ALARM RELAY

The starter interrupt relay, activates by a signal from the security control module, interrupts the starter circuit keeping the starter from operation.
In armed state, the system will not activate the starter interrupt relay and starter circuit functions normally.
The system activates the starter interrupt relay when the system is in alarm state, and keep this condition until the system is turned to disarmed state.
The headlight alarm relay is adopted in headlight circuit, and this relay activates when the security system is in alarm state.
In alarm state, the security control module switches the output signal ON-OFF alternately to flash the headlight via a headlight alarm relay.
The starter interrupt and headlight alarm relays employ the same parts and are interchangeable.
The starter interrupt relay and headlight alarm relay are installed behind the lower cover located under the steering column.

3. The instrument panel lights will flash when the parking lights flash.4. Your SUBARU keyless Entry System is equipped with two remote transmitters.

Programming Buttons Location

The Programming Button is located under the driver's side dash beneath the diagnostic connector (to the right and below the fuse block accesscover).

Adding or Deleting Remote Transmitters

Up to four (4) transmitters can be programmed to your keyless entry system.

NOTE:

Make sure no one is operating another keyless entry or security system within range of your vehicle when you are programming remotetransmitters. Another transmitter code could be inadvertently "learned" by your system, allowing someone unauthorized access to your vehicle.

To program an additional transmitter:

1. Open the driver's door.2. Turn the vehicle ignition to the ON position.3. Press and hold the Programming button* in.

-.

After approximately 15 seconds, the door locks will cycle 3 times. This indicates that the system is in the Transmitter Programming Mode. Donot release the Programming button.

4. Press the LOCK button on the new transmitter. The door locks will cycle once.5. Repeat step 4 for any additional transmitters.6. Exit the Transmitter Programming Mode by releasing the Programming button and turning the vehicle ignition off. Test all remote transmitters to
ensure that they work properly.

To delete a lost or stolen transmitter:

1. Follow steps 1-3 as described above.2. Re-program the remaining transmitters as described in step 4.

- If there is only one remaining transmitter, perform step 4 four times.

> Relays and Modules > Relays and Modules - Accessories and Optional Equipment > Keyless Entry Module > Component Information > Service and Repair > RKE

Installation > Page 22

Legacy GT LTD Sedan AWD F4-2.5L DOHC (1998)

- If there are two remaining transmitters, perform step 4 twice for each transmitter.

Your keyless entry system does not require any specific maintenance except for occasionally changing the transmitter battery. The 12-volt batteryin the remote transmitter should last approximately one year, depending on usage. When the battery begins to weaken, you will notice a decreasein range, or the distance from your vehicle that the remote transmitter will operate.(Battery not covered under SUBARU warranty.)

To Change the Remote Transmitter Battery:

1. Remove the phillips screw on the back of the remote transmitter case. Use a small coin to separate the case halves and expose the battery.2. Remove the old battery and replace with type GP-23A or equivalent.3. Close the transmitter case and replace the screw.

About Transmitter Range:

The receiver inside your vehicle security system and the remote control transmitters are designed together to have an average operating range of25-50 feet during ideal conditions. Although at times you may experience range greater than that, there may be occasions when range is less than

normal. Atmospheric conditions or interference from other RF-emitting devices can effectively reduce transmitter range.

This device complies with FCC rules part 15. Operation is subject to the following two conditions: (1) this device may not cause harmfulinterference and (2) this device must accept any interference that may cause undesired operation.
