Hi, You can try ebay for an owners manual. I have a 94 and it took a while, but someone from this forum gave me the idea, and they do end up there. As far as your alarm, I have included a description of how it should work. ( The battery in your remote key fob can be replaced, too!)
The anti theft alarm controller is solid state, but I would suggest checking each door switch, cleaning terminal and checking hood switch , are door lock actuators working right,too before messing with controller. They must all function properly for the system to work right. Also, you don't mention the alarm security light on your dash.....did it work when you got it, did it quit, etc; The more info y ou provide, the more people here will be able to help. Good luck

Vehicle Level Accessories and Optional Equipment Antitheft and Alarm Systems Description and Operation Anti-Theft System
The Anti-theft System consists of the following components:
Left and right door switches
Left, right, and tailgate door key detect and tamper switches
Engine hood switch
Door lock actuators
Left and right front door lock switches
"ANTITHEFT" indicator light
The arming sequence is initiated with the starter switch in the LOCK position and all doors closed. This results in all theft related switches to be open to ground. The "ANTITHEFT" indicator then flashes for about 30 seconds or until the arming sequence is completed. When the driver's door is locked using the door key, the door lock actuator internal switch will open, removing the ground signal from the anti-theft control unit input. Now all inputs to the anti-theft control unit are open to ground and the "ANTI-THEFT" indicator stays lit for about 8 seconds . The anti-theft system is now armed. If any of the theft related switches are grounded, the theft alarm is activated. The anti-theft controller does not allow the vehicle to be started by not applying ground to the starter relay. The anti-theft controller pulses a ground signal to the lighting relay causing the headlights to flash. At the same time, the anti-theft controller unit pulses a ground signal to the anti-theft horn, causing it to sound. The system alarm is cancelled when the anti-theft controller sees battery voltage at its ignition input or a ground signal at its key detect input.
The circuit consists of the starter switch, anti-theft controller, anti-theft horn, front door and tailgate key switch (detect and tamper switch)~ door lock (& power window) switch, door lock actuator for each door, engine hood switch, clutch start switch (M/T), ANTI-THEFT indicator light and mode switch (A/T). The system operates as follows: After locking the starter switch and removing the starter key (this sets the alarm), if the door is unlocked in any way other than with the proper key, the headlights start flashing, the horn sounds, and the starter circuit is disabled. (However, the engine hood and all the doors must be locked and closed.)
Once the system has been placed in the warning or alarm condition, it can be released only when the starter switch is shifted from "OFF" to "ACC" by the starter key, or when the lock of the front door or the tailgate is released (to activate the detect switch) by the starter key.
#19 of 383 91 trooper skipping problems
Aug 19, 2006 (5:09 pm)
Got 91 trooperII i can not find the ALDL link as noted. I have cleaned the injectors, replaced plugs, fixed a couple of bad wires. It ran great for about 10 miles. When I stopped it started skipping again. Got to different repair manuals both say check for codes, but cant find ALDL clip.

Hi, I posted a diagram on mycarspace.com at this location. Unfortunately, You will have to look at it there since I cannot seem to do anything else with it. I don't know if it is my settings or what??!! this is for the four cylinder engine. I think it may be different for 6 cyl. You can see that it is in console, about half way back and consists of two wire set. In the diagram, it is the lower set. Hope this helps

This is the first time this ever happened to me. I just filled up the tank, I was driving for about an hour, and then the truck started acting like it was going to turn off but then got back to accelerating. After that it didnt do it again that day. Then the next day, I was driving and I went and filled up the tank again and then it started doing it again. And then when I pulled over in the fuel tank where you gas in the truck, started coming out of the tank thru the cap. and poured all over the ground. I then opened the cap and a bunch of pressure was coming out of the tank. I am wondering if anyone knows what that could be.
#22 of 383 2001 Trooper Electrical Problem
Aug 27, 2006 (3:58 pm)
My wife's Trooper has something wrong with the electric system. The battery and alternator are ok but something is draining the battery down while the vehicle is setting and not running. I detect a slight spark when I unhook and hook up the positive battery cable. Anyone got any ideas on this?

Dome lights on because of a bad door switch or not quite closed door? Or if the dome lights are specifically turned off, the lights in the bottom of the door panels? An aftermarket stereo is standby mode instead of off? Faulty ignition switch leaving power on in general?
#24 of 383 2001 Throttle Problems
Aug 29, 2006 (4:48 pm)
We have 63,000 miles on a 2001 Trooper LS (4cylinder) & have never had any problems until now. When you step on the gas the car won't go more than 20 to 30 mph. My son was doing driver trainer on the interstate going 70 then suddenly it drops down to 15 to 20 mph and won't go any faster. It's been doing this for a week. We took it into an auto repair and they said they called a "hotline" and said it was a wiring problem. They replaced a wire. It worked o.k. for about 48 hours and now has the same problem. We've taken it back in and they're saying "gee maybe its a computer problem, we're not sure". They've kept it for 2 days now. We live in the middle of nowhere in the midwest so there's no dealership to take it to. Has anyone heard of this problem before? I'd appreciate any input!

Do you have the 4 cylinder diesel? If you do, how did you get it into the USA? And what's your MPG?
Or the 6 cylinder gasoline engine? I have not heard of a 4 cylinder gasoline 2001 Trooper.
#26 of 383 1995 Trooper II Transmission problem
Aug 30, 2006 (12:07 pm)
Hi - Long story short - Wife took the vehicle on 3 hour trip with tran fluid 2 quarts low. Transmission will only shift manually now. 1st through 3rd gears work manually with no fourth gear shift up when I go to D; just stays in 3rd. I can shift down from 3rd to 2nd to 1st with no problems. Placing the shifter in D starts the transmission in 3rd. It won't shift up or down out of 3rd. Somebody please tell me this is a simple problem to fix. This has been my 2nd Trooper - it now has 150K+ on it. Love this car .

Hi, It is possible for you to check for trouble codes on your vehicle. If you get a code and need help, post again.

Vehicle Level Transmission and Drivetrain Transmission Control Systems Testing and Inspection Testing and Inspection Procedures Displaying and Reading Trouble Codes
Displaying and Reading Trouble Codes
This is a link to a diagram of locating the jumpers.
DTC can be displayed by the Transmission Control Module (TCM) by shorting together terminals 1 and 2 of the TCM Diagnosis Connector (C-92) located left side of left instrument panel (This grounds the TCM pin D16).
After this, the CHECK TRANS Indicator will be OFF for 3.2 second and then will flash each DTC 3 times.
When there are more than 9 flashes this means that the indicator is constantly flashing, OFF for 0.4 seconds, ON for 0.4 seconds. In this case there is no DTC stored in memory. To find the problem without a scan tool and without DTC GOTO WITHOUT DTC CHECK.
When there are less than 9 flashes you will see DTC of 2 digits repeated 3 times each and when all codes have been displayed they are displayed again beginning from the first one.
Do not care about the DTC order : if "21" is before "22" it does not matter.
Write down all codes numbers and GOTO DTC CHECK.
IF CHECK TRANS indicator is not flashing GOTO "CHECK TRANS" CHECK.
