this is the third time this has happened and i think it finally went out for good. my security light in my dash doesnt shut off and my car wont start. but it has done this before and the other few times i left the car sit and the light went away and the car started after about 20 minutes. this time it hasnt started yet and i need to put it back away and cant get it running.what could cause this. help please

 

This is happening because the VATS control module is reading the resistance in the keys pellet as being the wrong resistance value and therefore will not allow the car to start for four minutes until it resets. During this time, if the key is still in the on position, the security light will remain lit. This problem is caused by either dirty or worn contacts on the key or in the lock cylinder. Clean the key with electrical contact cleaner and then lightly moisten a thin piece of cloth, wrap it around the key and slide the key inside the lock cylinder just far enough to clean the contacts in it. Let it dry for a minute or two and then try it.

 

i tried this and it worked but now i shut the car off and it isnt starting again same deal

 

Have you tried measuring the resistance on the key with a multimeter and then putting the key in the lock cylinder and measuring its resistance through the wire harness with the key off?

 

no i will try that tomorrow i also have a car alarm with remote start would therte be a bypass relay or something that might be going bad i am getting the alarm removed this spring it has been nothing but trouble

 

you might have to bypass the vats with a resistor .. get the value off the key and get a resistor the same value and splice into the two small white wires from the steering column and by this eliminating the key all together. the resistor takes place of the key but the security feature of the vats is gone then. if you want security then get a good alarm with a starter kill. and some other things like keyless entry and trunk release( if eq.). and if the car is fuel injected and a auto trans get one with remote start. and or a two way pager system lie the dei units.

 

There could be, I had an alarm in my 92 RS but it didn't have the remote start function on it,

 

my alarm does have all those features its just still been nothing but problems i think the installers suck

 

what kind of alarm is it ? those cars are very easy and it is just about a no brainer to install in a 3rd gen.

 

its a viper 790 vx responder and it was good at first but i keep having problems of course after the warranty is up

 

Isn't that always the case, one minute after the warranty expires, so does the product.

 

i figured out the problem i think there is a little plug with orange electrical tape on it and i unplugged it and my car started i have no idea what it is i am going to see what it is tomorrow in daylight.

 

that should have a lifetime warranty that unit is not that old. does that remote light grey in color or the carbon fiber looking remote? that had a lot of trouble with the light grey remotes they quit working all together and you had to send the remote and the brain in to get fixed. but know they are replacing the old remotes with the carbon fiber looking ones the supposedly the fix for the non working remote.

 

If you can, post a picture of it. I am curious and have an enquiring mind. I have a feeling it has something to do with the remote start function of your alarm system.

 

mine has quit working like 3 times now they just keep giving me a nwew remote and it did it just this winter while the car is in storage

 

yea my remote has quit working like 3 times they just keep giving me a new one here are some pictures

 

backside

 

are they replacing the alarm while you are there? or are they sending the unit in ? if they will not help you I work in a audio store and I install remote starts and alarms I can send it in for you( if needed)

 

i went yesterday and they gave me a new alarm system free of charge

 

with a sweet orange backlight

 

Sweet!!!!!!!!! Has that fixed your problem?

 

yea so far it has hopefully now i can figure out my problem with my brake lights
