Glad you fixed it. Just to add another mistery alarm issue to the list: I sometimes get a no start (cranks but no start) but when I open the drivers side door, it start right away...
Any ideas?
Leo 1984 Euro S2 5 spd
On my 1990 RHD s4 can someone please let me know where I can find my alarm control unit 92863710403? I located the alarm relay 92863716000 and replaced that, that seemed to fixtheproblem, so I didn't look for the control unit before putting it all back together.
Now I think the original intermittent no start problem has returned so am keen to know where the control module is before starting to pull things apart to find it.
Dave, on my 89 its in the dead space behind (to the left of) the glovebox in the front left corner of the cabin. Not sure whether that's the same as your car, as a few other control units moved around in 1990.
87s4 aut. i looked at my glove box rear, and i found nothing there. i removed passenger cover near rocker panel and i found an ampliflier and this box...is this the alarm?
i am currently troubleshooting a crank and no start.
My factory alarm gave me nothing but problems. To start the car I would have to open the rear hatch, slam it shut, the car would honk, then I would be able to start it. It would then shut the engine off when it felt necessary. I had it disabled and what a relief. I really don't see the need for a car alarm. The first year I got my car, I had enough problems (for one reason or another) trying to start it with the actual key - I'd like to see a thief try and get it running without one.
I had to do the Sam thing to get mine to start. Until about a month ago. My car is completely shut down and won't start. Any idea how to disable the alarm system? I found where its at already but do I just take the box out or what and if it doesn't start after I disable it what should I check? And should I get a new alarm system? I need to get this baby running again..its killing me just letting her sit in the driveway loll.
You have to run a jumper wire across two pins in the plugs just below the CE panel
Which two pins is dependent on the year of the car.
Jumping the wrong pins for a given year is a bad idea. It lets all the smoke out of some of the wiring and a couple components. It's pretty expensive to put that smoke back in.
Got to love old threads. I have been chasing this ghost for 2 years off and on. Finally chased it to here and I think I am good to go. I have thought that before, but we will keep our fingers crossed
Does anyone know what each wire does on the factory alarm connector? i have a 87 s4 U.S model. the alarm has long since be removed and bypassed. i know pins 1 and 4 feeds the EZK relay with power. what do the other pins do? IE which ones control door locks, horn,lights, door open inputs,? im installing a key-less entry with push button/remote start. think most of my connections should be at the connector already. srry i could not read nor understand the schematic in the above post.
Example of what im looking for would be as follows
pin1. +12v to energize EZK
pin2.?
pin3.?
pin4. EZK 12v energizing input needs to be fed from Pin1.
pin5.?
pin6.?
pin7.?
pin8.?
pin9.?
pin10.?
