Can this cause this?

I cahnged brake light bulbs in VX Friday, did not drive it all weekend, since Monday the ABS has been on and off nad as off today it is on all the time. Isuzu dealer said it could be the bult fastener is not screwed in correctly or loose...Does this even seem possible as a cause? Thanks

Ugh - you just NEVER know with electricals, but no, changing a bulb should not somehow feed back into the ABS controller and throw a fault.

That said, what kind of bulbs did you put in there?
