1992 firebird VATS problem

I lost my keys to my car, so I bought new keys with the ignition tum, then I bought the VATS bypass module from eBay, I put a multi meter to the Vats connector going to the car, it's reading 4.67, which is 4600 resistor, so that is what module I bought on eBay, number # 11, but when I turn on the car, dash lights up, security light stays on that tells me the bypass is not working, PLEASE HELP me get her started

Re: 1992 firebird VATS problem

What sort of bypass did you buy ? One that just bypasses the key cylinder ?
or like this ?

Re: 1992 firebird VATS problem

Btw if you lost your keys how did you determine the vats resistor value ?

Re: 1992 firebird VATS problem

You need to read the value of the key, not the value of the car.

Re: 1992 firebird VATS problem

You will need a locksmith or someone to test every resistor value on your car to determine what chip it needs. Lost my keys before and had to have someone come out to make a key and test for the correct chip.

Re: 1992 firebird VATS problem

If you don't care about VATS, get a key cut off your serial# at the dealer (must be a VATS blank), use your original tumbler, and bypass the VATS relay by connecting the power in and power out wires. The relay is behind the kick panel by the drivers foot.

Re: 1992 firebird VATS problem

If you want to keep it all stock one of the easiest ways to do this is get a bag of resistors. There are 15 possible values the key may have. Look here https://www.thirdgen.org/vats_passkey_system/

Here is the catch each test will disable the module for for a few minutes (I usually say 15 min to be safe). So you will need to test a different resistor value every 15 min or so. You can also do this with a potentiometer just use a multi meter to dial in the resistance for each test.

Testing the resistance of the module doesn't tell you anything.

Once you have identified the right resistor value you will need to go to the dealer (or ebay) and buy a key blank with the right pellet and have it cut to match the key that came with your new cylinder. Or use the resistor you found to by pass it.

Or if your really don't care about VATS working buy this https://www.hawksmotorsports.com/vat...maro-firebird/ and follow the install instructions, this will remove the need for a VATS key or a resistor bypass.

Re: 1992 firebird VATS problem

Here is a bypass like the above but cheaper and I believe it’s duel frequency 30 and 50hz.
https://www.ebay.com/itm/GM-VATS-or-...ss!20876!US!-1
If you state your year make model and engine type I can let you know how to wire it up. Or if you choose reprogramming send me a pm I can assist with that . It’s better to keep a working vats system for vehicle theft especially since it worked before the lost keys. With the bypass you need to jumper the starter enable relay under the drivers side kick panel. The two large gauge wires usually green and yellow otherwise the engine will not crank over.

Re: 1992 firebird VATS problem

To wire up the vats bypass module from eBay.
you need power. You can get accessory power at the ecm a6
this is a pink and black stripe wire. Then a ground at a12 a black with white stripe wire.
the module signal wire which you will have to try either wire I think ists a 30hz signal hooks to a blue wire at the ecm pin f10.

Re: 1992 firebird VATS problem

Here is a wiring pinout for a v8. The wires should be at the same location as your v6.

Re: 1992 firebird VATS problem

You should contact the seller . It looks to me since this is a duel frequency device you get 30hz out of the white wire if the blue wire is grounded. You get 50hz if the green wire is grounded. Ground the blue wire and cut f10 at the ecm a blue wire and hook the devices white wire to it.I believe that’s what the blue and green wires are for. You can try grounding one wire and try cranking it over if it fires up it’s right. Wait 5 min or so and try grounding the other wire.
just a educated guess but maybe your instructions are better than the eBay schematic.
Dont forget to bypass your starter enable relay pictures on post 14.

Re: 1992 firebird VATS problem

It could be under the tar tape or tucked up under the dash.

Re: 1992 firebird VATS problem

Did you find the starter enable relay?
The passkey module canít be reprogrammed so they told you false information.

Does it have a large purple wire, if so probably the relay.

Re: 1992 firebird VATS problem

Sorry had 3ed and 4th gen relay confused in my head. Should have a thick yellow and thick green/white wire.

There is a mat/ sound deading that covers it up under the plastic kick panel that wraps into the door jam.

Re: 1992 firebird VATS problem

It did have a 10 amp fuse, is this the ecm, cause I have the vats bypass I think I need to wire it to the ecm

Re: 1992 firebird VATS problem

That is the ecm, but you will still need to bypass the starter relay in addition to the module. The model just tricks the ecm into thinking vats sees your key otherwise injectors and fuel pump are disabled.

Yep, that's cause it's a 92. The style of relay changed near the end of production.

Re: 1992 firebird VATS problem



Looks like the right relay. If You backprobe or remove the relay. You should have power on the yellow wire if you turn your key to the cranking position.
or ground the yellow with black stripe wire at the relay.
