I had success, but it likely cost me $105 for a module re-build that I didn't need. After getting the three lights of death, I just flipped a coin and sent the module off to ATE for a lifetime guarantee rebuild. They advised they would test it first, but rebuild it even if it checked "ok" as the heat will get it sooner or later. Got it back and the errors were still there. Did the "diode test" and 3 wheel sensors showed just fine and the front passenger was open-clearly bad. Replaced it for $65 from AutoHauz and all is good once again. Don't even need to clear the error. It clears itself.
