The first alarm dedicated to the 9000 wasn't very adjustable and you probably had trouble with it and had the update done to it. If not, here's how to reconnect it after battery or fuse 22(early 89s) or fuse 19(others) puts it in transport mode. You don't want to leave it in transport as it is easy to enter diagnostic mode from there and when in diagnostic mode, the starter disable function will be triggered and the car won't start. If the LED in the left speaker grill flashes once every 4 sec., all the time, the car is in transport mode. To get to transport mode either disconnect the battery or pull fuse 22.(or fuse 19)
REARMING ALARM FROM TRANSPORT MODE
To reconnect the alarm with motion detector on, close everything and turn the key in the driver's door three times in 2 seconds to unlock. The LED should go out. Open the driver's door and close it, lock the door. After the interior light goes out, the alarm should arm in about 10 sec.. The LED will flash once per sec. You now need to adjust the sensitivity so false alarms from the motion detector won't occur.
DISABLING MOTION DETECTOR TEMPORARILY
With doors unlocked but all closed, hold the key in the driver's door to lock for three seconds. Arm alarm normally by locking door. Motion detector will be deactivated until door is unlocked again with key. It will then return to program setting and function.
DISABLING MOTION DETECTOR PERMANENTLY
Open the driver's window. Go to transport mode. Turn key to unlock twice in 2 sec.. The siren should beep. The led should flash once every 2 sec.. Within 10 sec. of the siren beep, open the hood. The LED should go back to one flash every 4 sec.(transport). Turn driver's lock three times to unlock within 2 sec.. Open and close the driver's door and then lock. The alarm's motion detector will be deactivated until the battery or fuse 19/22 is pulled again, at which point rearming will necessitate reprogramming the motion detector sensitivity. Other functions are the same.
ADJUSTING MOTION DETECTOR SENSITIVITY
Open front windows, close all doors, trunk and hood. Go to transport mode. Turn drivers door key to unlock twice quickly. Siren should chirp and LED will flash once every 2 sec.. After 10 sec., LED will flash twice per second. To decrease the sensitivity, turn the key in the driver's door to lock, hold for two sec. and release. This decreases the sensitivity one step.( Alarm reverts to 3 steps above most sensitive when fuse or battery is pulled. There are 240 steps to the least sensitive setting.) 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 it by turning the key to lock until it doesn't sound with the snap. It usually takes 30-50 steps to get the mirror test to work. When you get it like you want it, turn the key to unlock twice quickly to set the adjustment in memory. LED should again flash once every 4 sec.(transport) Turn key to unlock 3 times in 2 sec.. LED should stop flashing. Open door, close door and lock. Alarm should arm with your programmed setting. It will have to be reset anytime battery power is lost to alarm. To make alarm more sensitive, follow same instructions, only turning and holding the key for 2 sec. to unlock
