Question about 1998 Dodge Intrepid

1 Answer

Car computer / factory alarm problems?

It first started when the car would turn on for about 2 secs then shut itself off, after about 3 to 4 attempts the car would not crank over at all.. when it finally would crank then my gauges & a/c stopped working..when i ran the self test by clicking forward three times the ignition key i recieved the following codes p1684 ,p1289 ,p1698 ,p1695 , p1687.. i then disconnected the negative post on my battery overnight , the following day reconnected and all seemd fine everything worked (gauges & a/c) .. well the next day it started doing the exact same thing all over again , now it will start but i have no gauges working & my a/c also stopped working ..seems to be driving normally , no hesitation or stalling , i did notice that when first turned on the check engine light will come on after about 30 secs followed by my factory alarm light (ontop dash) will light up as well and stay lit continuously , it had never had done that before .. also i am not getting any error codes at all using the self key test ..also since my a/c isn't working i do not know if my fans will turn on ..i haven't heard them activate at all final note when i click the key forward all the lights on my display panel will light up except the check engine light ...but that one will turn on after about 30 sec's of idling... could it be that i have a bad BCM/PCM/TCM?? which one though since i am not getting any error codes anymore...or could my factory alarm create this kind of problem..
any help will be appreciated
thx N.S.

You may want to take this car to a competent mechanic for dianosis before swapping parts. Most cars built after 1996 have multiplexed wiring which is not exactly easy to fix and you can spend a lot of time and money fixing the wrong things. Other than that, you may want to make sure the ground straps on the engine, as well as the battery cables, are clean, tight and in good condition. Battery cables only last about four or five years on the average car, which is about as long as a battery does.

Both codes you have listed are CCD bus communication faults. I find it very unlikely that the ignition switch is the problem. The first thing I would check is the two 10-way connectors located below the battery tray, one gray and one black. What typically happens is that the battery leaks and drips onto these connectors. The "bus" wires also pass through these connectors. I would recommend a thorough inspection of the connectors, even the back portion where the seal is. Clean with electrical contact cleaner and apply a thin coat of dielectric grease. Also check the wires around the connectors to make sure they have not melted together.

SOURCE: 2002 Dodge Durango with DTC codes P1687, P1698 and

Welcome to

These codes are part of a loss of communication between power control Module and transmission.
It is advised to go to dealer and have the computer re flashed.
Control Module and the Power Control Module is lost. Sometimes this happens when a PCM, or TCM is replaced without being flashed, a bad connection at the PCM, TCM, or a bad TCM.
Was the battery disconnected at all?
Was the truck jumped or did truck give a jump to someone?
Let me know, Lee

Hmmm, a puzzle.

The only way to disarm these alarms is with
the factory remote or turning on the ignition.
To turn off the factory alarm.

Ok, do you have the remotes?
If so, let's ID the system.
Go to & use th fcc #s
on the back of it.

If not try this:

Programming Factory Security on GM Cars and Trucks
Instructions for programming the GM factory security systems that do NOT
disarm from the driver's door key cylinder. This programming is for the
cars and trucks listed below.

96+ Camaro
96+ Firebird
99+ GM Trucks
99+ GM Sport Utility Vehicles

Step #1 Turn the ignition on then off.

Step #2 Remove the radio fuse only (not the fuse that says acc/radio).

Step #3 Turn the key to the accessory position. When you do this you
will get two chirps from the door buzzer. Should you hear only
one chirp, your vehicle does not have factory security and these
instructions do not apply. You need to hear two chirps.

Step #4 Press the unlock switch on the door. This will give 1-4 chirps
depending on the program step. Continue pressing the unlock
switch until you get to the desired chirp setting.
1 Chirp - Security off
2 Chirps - Remote Only
3 Chirps - Factory Setting
4 Chirps - Passive Arming

Step #5 Turn the ignition off.

Step #6 Put radio fuse back in.

Every time I open the door nad drive the car, then shut it off the alarm goes off and I can not find a way to shut it off. How do you do it? I also do not have the key fobs.

quickest way i know of here is providing its a factory immobilisor and not a boy racer add on then take the chip out of the key and tape it under the shroud next to the transponder ,This way the car thinks its got the key in and this will stop the alarm

My 96 Jetta intermitently will not start unless I turn the alarm on and then back off. The last time I had to hit the panic button on my remote, turn it off, and then the car would start. This seems to... reset the factory immobiliser/alarm you must unlock/hold key over 30 secs....then lock/hold key over 30 secs....then press unlock button on remote for 30 secs....reset.(if you disconnect the battery you will have to reset AGAIN and input radio code.)

yes the remotes do have batteries. how ever that might be your problem or the remotes lost its code for programing. step when turning alarm off---- if its a factory alarm put the key in the drivers door when the door is closed and lock then unlock it thats the manuel shut down for factory. step 2------- aftermarket alarm. look for a valet switch most likely it would be installed by the driver kick panel or by the under dash fuse box. when u find it put the key into the ignition. turn it to the run position. within 3 seconds press and hold the valet switch for 3 to 5 seconds you should here a confirmation chirp and the led light will stay on solid and wont blink give it a world let me know what happens

1999 Volkswagon Jetta Alarm System

I also have a 99 Jetta and I ran into this problem once or twice. How long do you wait in your car after closing the door before trying to turn it on? I've found that the car sometimes will automatically lock itself and engage the alarm system if you are inside of it for over 30 seconds without making an attempt to start it. When this happened to me, I would hit the unlock button on my keyfab twice and then attempt to start the car. Lemme know if this works for you!
