Good afternoon everyone. I have a 2007 Ford. Lariat. Sometime the engine light is on, sometime the airbag light is flashing, and sometimes the ABS light is on; and sometimes they’re all on at the same time. Could it be a problem with the computer and it needs to be reset? I am open for suggestions.

 

What computer do you want to reset? That’s three different systems you need to diagnose.

Please give some background about this truck. Most times someone present a case like yours (a well used Lariat with a 3V 5.4 is a bad start), it’s because they bought a POS sight unseen for cheap and expect miracles.

 

Sounds like a short in the instrument cluster, it's a common problem with 04-08 model years as they get old.

 

I'll second that. If you access the instrument panel's wire connectors, then jiggle them while watching for a change in those lights, you may be able to find the problem.

If that doesn't pinpoint the problem, you can resolder the cluster's solder joints. It's a frequent problem here that a hairline crack develops in the solder joints. If you briefly touch each solder joint on the board with a fine tip soldering iron to remelt the solder, that should remove the crack(s).
