Mitsubishi Repair Problems? Ask a Mechanic for Answers ASAP
Yes, the low voltage is capable of setting warning lights in the ASC/ABS system, the SRS system and the MFI systems. I would still go ahead and scan it (about 90% odds the codes will still be there), but the likelihood of it being anything other than voltage related (IG voltage low, pump voltage low, etc) are very slim.
I would definitely at least load test if not replace the battery though. It should not have gone that low (that it couldn't start the car) after 20 minutes, even if the key was fully on (as opposed to ACC). It is likely on its way south.
Absolutely, I'll be here if you need more help of course.For a 2011 I would expect to see something like:P0221 (throttle voltage plausibility)P0620 Generator circuitP0622 Generator FR
P1603 Battery backupP1609 Battery currentPretty much any U code (bus time out) like U1100
It all depends on what level of discharge we were at. For example you could have voltage high enough the computers/bus didn't have a shut down, but the resulting sensor voltages (being scaled down from their reference voltage) read low instead.The big thing is the light went out.... meaning the odds of it being battery related and once the voltage was normalized the code cleared is pretty high. It would be unlikely to be some "other" problem completely unrelated to the event.
I am stepping out briefly for a break; if I am not here when you reply/update I will get back with you as soon as I am in.
No need to reply to this post otherwise :)
Thanks, ***** ***** almost definitely be related.P1590 is a torque reduction request due to a communication problem between the engine ECM and the transmission TCM.
Basically the power drops low enough that some of the computers can't stay online, this code sets. The alternative would be a physical wiring/bus issue which would not only be terribly unlikely, it would not likely go away either. The power supply being too low to maintain communication however would go away once the voltage is restored to 12V+ and the key is cycled once or twice without the power dropping again.
