If pulling fuse 19 and reinstalling it has no effect on the LED, you have this latest, most reliable ECU. This ECU will remember your programming when the battery is disconnected via an EEPROM. It is also more difficult to get into transport mode ( not likely to inadvertently get into transport, accidentally, anyway).
TRANSPORT (SERVICE) MODE
(To get back to regular mode no matter what mode you get into, just turn the key to unlock 3 times within 2 sec.)
Open the trunk or the hood. Open any door except the driver's door. Turn key in driver's door to unlock and hold for 10 sec.. Release key and wait 5 sec.. LED should flash once. Turn key to unlock twice in 5 sec.. LED should flash once every 4 sec. (After 5 minutes it goes out). Shut everything up.
ADJUSTMENT OF SENSITIVITY
Go into transport mode. Close all doors, hood and trunk. Turn driver's door lock to unlock and hold until siren blares and lights flash. LED should flash once every 2 sec.. Wait 10 sec. later and the LED will flash twice per sec. To decrease sensitivity, turn the key in driver's door to lock and release. Wait 2 sec.. This moves the setting one step. You can go 13 steps from the default setting and then the siren will chirp, telling you you are at the limit. To increase sensitivity, follow same procedure except turn to unlock instead of lock. Repeat the adjustment(turn to lock, hold, release), until you can pull the driver's mirror to a position just before it locks and letting it snap back in place without triggering the alarm. If the alarm sounds when you snap the mirror, it will quickly stop and you can continue to adjust sensitivity by turning the key to lock until the siren doesn't sound with the snap. When you get the sensitivity so that the mirror snap doesn't set off the alarm, turn the key to unlock twice within 2 sec.. The LED should flash once every 4 sec.. Then turn key to unlock three times within 2 sec.. Open door and close, then lock door. Alarm should arm with your programmed sensitivity and will hold it even if the battery is disconnected.
NOTE: Turning the key to unlock three times in 2 sec. when not exiting transport mode will set the sensitivity back to the default setting. like disconnecting the battery on older cars. Just do the three times to unlock to exit transport. After you are out of transport, doing it will wipe out your programming, and reinstall the default factory settings.
TEMPORARY
DISCONNECTION OF MOTION DETECTOR
(Such as when using a ferry,
etc.)
After getting to transport mode, and with all doors, hood, trunk closed, lock driver's door and hold key to lock until siren chirps. Motion detector is now turned off, but remaining functions are active and alarm is armed. When driver's door is again unlocked and locked, motion detector will again be connected in what ever setting you programmed it
PERMANENT DISCONNECTION OF MOTION DETECTOR
Go to transport mode with everything closed except the driver's window(so you can reach in and open the hood later). Turn key and hold to unlock until siren chirps and turn signals light for 1 sec. LED will flash once every 2 sec.. Open the hood. Motion detector is turned off and LED flashes once every 4 sec.. Turning key to unlock three times will allow other alarm functions to work. Now every time the driver's door is locked, the siren will chirp to remind you the motion detector is turned off. It will not reactivate when cycling the key. To reactivate the motion detector, re enter transport mode, shut all doors, hood, trunk, and turn key to unlock three times in 2 sec.. Check sensitivity with a mirror snap. Reactivation may reset sensitivity to factory level. You will need to reset it if the alarm sounds with the mirror snap.
