Pressing the UNLOCK button on the remote transmitter once unlocks the driver s door. Pressing the UNLOCK button twice unlocks all doors (and liftgate). When any or all of the doors (and liftgate) are unlocked, and the dome light switch is in the DOOR position, the dome light will illuminate for 15 seconds. The turns signal/hazard lights will flash once. Pressing the LOCK button on the remote transmitter locks all doors and the liftgate or trunk. When the any or all of the doors (and liftgate) are unlocked, and the dome light switch is in the DOOR position, the dome light as well as the turn signal/hazard lights will flash twice. With the answerback feature in the default mode, the horn will also sound once. The answerback features can be customized. Refer to the Answerback Operation and Modification section of this bulletin or Group 42 in the service manual for more information about the RKE answerback features. Pressing the TRUNK button on the remote transmitter (if equipped) twice within five seconds will unlock the trunk lid. The trunk lid must be closed manually after it has been unlocked. If the UNLOCK button is pressed while all doors (and liftgate) are closed and no door is opened within 30 seconds, all doors (and liftgate) will automatically re lock. On vehicles with factory installed security alarm systems, the remote transmitter will have a PANIC button. Locking/unlocking the doors will arm/disarm the alarm system. Pressing the PANIC button will activate the alarm system, flashing the headlights and intermittently sounding the horn for about 3 minutes. Pressing any button on the remote transmitter will deactivate and silence the PANIC alarm.

To turn the function on or off when the doors are unlocked, release the UNLOCK button and then release the LOCK button. A tone alarm/buzzer will sound once when the function is turned on and twice when the function is turned off. ENABLING/DISABLING THE HORN ANSWERBACK FUNCTION The following steps will set the horn answerback function to one of two different modes. These steps must be done with the key removed from the ignition switch. 1. Press and hold the LOCK button for 4 to 10 seconds, then press the UNLOCK button during this time. 2. Release the LOCK and UNLOCK buttons at the same time. A tone alarm/buzzer will sound to indicate the current mode: One tone/buzzer: The horn will sound if the doors are locked with the keyless entry system. Two tones/buzzers The horn will not sound, even if the doors are locked or unlocked with the keyless entry system. Three tones/buzzers: (For Eclipse/Eclipse Spyder, Galant, Lancer/Lancer Evolution, & Outlander ONLY): The horn will sound if the doors are already locked and the keyless entry system is used again. In this mode, the horn will only sound when the keyless entry LOCK button is pressed again to confirm that the doors are already locked.

5 Page 5 of 7 OMRON A SYSTEM DETAILS: OMRON A System (2003 Diamante & Montero Sport) (Factory installed See Group 42 in service manual) OMRON A Transmitter Programming: HOW TO REGISTER THE SECRET CODE: Each transmitter has its own stored secret code. When replacing the transmitter, receiver, or when an RKE problem is diagnosed as a secret code registration fault, the secret code must be registered in the receiver EEPROM. Since only two different codes can be stored in the EEPROM memory, when the registration procedure below is repeated twice, the old previously registered code will be cleared. Registration of the secret code should only be done after confirming with the key that the door lock function operates correctly. 1. Check that all doors lock and unlock properly when using the key. 2. CAUTION Always turn the ignition switch to OFF before connecting the scan tool. Connect the scan tool (MUT II) to the data link connector (or ground pin No.1 of the data link connector if a scan tool is not available). 3. Within 10 seconds after connecting the scan tool (or grounding pin No.1 of the data link connector), turn the ignition switch to the ON or ACC position and then back to OFF a total of three times. During each cycle of the switch, make sure the switch remains ON for at least 1 second. NOTE: The doors will lock and unlock once at this time indicating that the system is in the registration mode. 4. Press either the LOCK or UNLOCK button on the transmitter to be registered three times within 10 seconds. The code is now registered. 5. After registration is completed, the door will lock and unlock once. 6. If there are two transmitters, register the first, then register the second using the same procedure within one minute. After completing the second registration, the doors will lock and unlock once. NOTE: The registration mode will terminate under any of the following conditions: When registration of the two transmitter secret codes is complete. When 1 minute has passed after registration mode is started. If the scan tool (MUT II) is disconnected (ground is released ground removed from data link connector pin No.1). If the ignition switch is turned ON. If any door is opened. 7. Disconnect the MUT II (or remove the ground from the data link connector pin No. 1) and remove the ignition key. 8. Verify that both transmitters operate properly.

The RKE functions and receiver module are integral with the ETACS ECU Model Year DENSO Model Year OMRON NOTE: This OMRON C RKE System system is similar to the OMRON B system introduced for the 2001 model year in the Montero. This OMRON C system is used in the Lancer Lancer Evolution, Outlander and with the 2002 model year replaced the previous DENSO system in the Eclipse, Eclipse Spyder, and Galant. This OMRON C system operates in the same manner as the 2001 DENSO system, however, the transmitters are different. Though the OMRON transmitters and the 2001 DENSO transmitters appear to be identical, they are NOT INTERCHANGE- ABLE. No model year Mitsubishi vehicle uses the DENSO transmitter. When programming new transmitters, make sure you have the correct part. Refer to the PARTS INFORMATION section of this bulletin for transmitter part numbers. OMRON B & C RKE System Transmitter Programming: 1. You can program up to 4 transmitters. You must program all transmitters at the same time. 2. Insert the key into the ignition lock on the steering column. Do not turn it on. 3. With the ignition key off, connect the MUT II or MUT III scan tool into the data link connector (or ground pin No.1 of the data link connector if a scan tool is not available). 4. Within 10 seconds of plugging in the MUT II or MUT III (or grounding pin No.1 of the data link connector), press the Hazard switch 6 times. The door locks will cycle indicating you are in the programming mode. 5. Press either the LOCK or UNLOCK button on the first transmitter slowly three times within 10 seconds. The power door locks should cycle after the first transmitter is programmed. 6. Press either the LOCK or UNLOCK button on the second transmitter slowly three times within 10 seconds. The door locks should cycle after the second transmitter is programmed. The same procedure applies to the third and fourth transmitters. 7. Disconnect the scan tool (or remove the ground connection from data link connector pin No.1) then remove the ignition key. Verify that all transmitters operate properly.
