so from the reading the titan issues, it appears (dont quote me as i dont know the details of the titan recall or the issues with our cars) some kind of vapor exists and causes the contacts in the relays inside to corrode.
so i suppose if you do get stuck and no help around, try unplugging this unit from the car, shake the hell out of it (maybe even kick it around gently on the pavemet to induce vibration to loosen the corrosion), and plug it back in.
jokes aside it might get you going for that one time you need the engine to start. atleast worth a try.
kinda like a defibrillator tactic.
