Hey bro. no problem......I think he's probably referencing the brake switch which not only works your lights but sends separate info to the TCU. It's right under the dash where you'd think it would be. It's strange because I didn't think it would put the car in fail safe mode though. The F1 position sensor would also cause similar issues. Additionally, when it comes to the air bags that's one thing the Leonardo or aftermarket computers have a problem with. Mine won't reset the airbags. That's something the sd2/3 most of the time has to do.
Also make sure your heater core isn't leaking on top of the airbag module that's what set my airbag light off. I bypassed the heater core until I changed it out in my Spyder. Now my GS heater core is giving me issues. They all fail just a matter of time.
Sorry brother if it seems I'm not consistent with the responses. I've been working really hard lately. I'm putting ARP head studs in a customer's diesel truck. I think you'd be fine to drive it honestly. As long as you're not hearing any weird lifter tap or motor rap I'm pretty certain you'll find it's okay.
Yes I do think that's what the problem is, and to be honest these cars aren't the best with the gauges whether the oil or voltage. Not a month ago my customer from Florida sent me a small video of the oil warning light fluttering on/off and I told him the same thing. You could do two things to be certain. Either change the sending unit.....(be sure to make sure the hole you screw the unit down into is clean of debris when you mount the new one), or two put a mechanical oil gauge in the hole and check it that way. If it's just the sender when you put the mechanical check gauge on it will stay consistent. My money is on the sender or the plug going to it shorting out. Check those first. It's a bit of a hard location, on the back side of the intake manifold close to the firewall.
