Dodge Durango: left key in accessory position and battery died

Customer Question

left key in accessory position and battery died of course, now we have lights on dash. Traction light, airbag, abs, and security red dot. Runs and drives ok, thinking a sensor is bad/needs unplugged but not sure.

hi i'm bill
welcome to just answer
please remember I am NOT there in front of you! my answers are based on your information
you will need to have the codes read BUT it is very possible the dead battery set low voltage codes and they simply need to be erased WITH a dealer level scan tool (not necessarily a dealers scan tool but a shop with one that has the same abilities)
the newer cars (starting around 2004) with far more sophisticated computers will set a fault code for low voltage if the battery goes dead. and simply disconnecting the battery WILL NOT erase all of them.
Customer: replied 2 years ago.
will low voltage "trip" stay indefinitely or would it time out with driving? Just curious, because this car doesn't get driven much. This happened a few months ago and don't know if we've driven/cycled ignition enough for a "driving cycle" to clear codes, if it would even clear codes. Either way will get to a scan tool when I can and report back results. Father in law worked for city garage and we've used it many times but he retired. Maybe his buddies can loan it to us. Will respond back in time and leave window open. Thank you.

no these types of codes do not clear on their own they must be cleared with a scan tool this is by design and by federal law on some of the computers
