Hey does anyone know what F lamp stands for on the Pontiac system check? Car is an 1988 trans am gta 5.7 tpi

 

Bump

 

Can't tell what you are asking. Can you be more specific?

 

I have no idea what you are talking about

 

I believe he is talking about a digi dash?? I have no idea...Ive never had a digi dash

 

Here is what I found when using the good old google.

I honestly have tried looking and posting on firebird nation and got nothing I have no access to pc

 

Did you read the link I posted?

 

Yes I'm gonna try what they said to do

 

The GTA digital dash light monitor works by checking resistance in the bulb circuits against other circuits of the same type (checks the left turn signal against the right for example. I am not certain of the exact process). If there is a difference in resistance it throws a "F Lamp" (front lamps) or R Lamp (rear lamps) at you to get you to replace the burned out bulb. Sounds cool right? never have a burned out turn signal again!

The problem is that due to the sensitivity of the system, once you replace that burned out bulb the system checks the resistance and thinks the other bulb on that circuit is now burned out because it has higher resistance. so you have to replace BOTH left and right bulbs of whatever type when you replace one. If this is break lights that means every time a bulb goes out you are replacing all SIX bulbs in the back, and probably both front turn signals as well. couple this with 25 year old ground connections and you have a recipe for an annoying beep every time you turn the headlights on. and then every time you hit the breaks.

So, you can fix this probably. replace all of your bulbs, check all of your grounds.

Since that sucks, many GTA owners, myself included, just unplug the "brain" of this system from under the dash allow the system to think everything is fine. the brain hangs down next to the fuzebox. I had to pull unreasonably hard with a pair of pliers to get the circuit board out of the box. see this link for a helpful photo.

The best way to remove that circuit board from inside the housing is to use a screwdriver,... insert it into the small "slot" at the top of the circuit board and use the plastic case to provide leverage so the board will pull free from it's plug.







I do NOT recomend any type of pliers as they could possibly damage to the circuit board.

 

Good point. Do what John says.

 

Fog lamps maybe?
