2008 Jeep Liberty error code gate on dash and interior light will not turn off got new battery and still doing it
can i buy a comma? says vanna white?? LOL !
ok, the battery drains, so you got a DRAIN, called phantom drain.
or dark current.!!
we use a thing called an AMMETER (DMM) to find all drains, easy
do you have one, want to learn or just wanting wild guessing.
on any 08 liberty, we check the scan tool data.
oops it shows battery low, wow even the PCM sees that.
new batteries do not fix drain.
nor dead alternators.
get it serviced, by a pro. ?
1: charge battery (rested its 12.6vdc )
2: start engine, scan tool shows, what DTC errors (post em')
3: battery voltage is , 13.3, to 15vdc running, if not charge system is faulting.
4: ok all that is ok, i then key off and measure bettery cable neg lug drain current, if 0.010a to 0.040a its ok, if over 0.1 amps its a drain.
we then find the drain cause, ASK? its not hard with a meter.
but i bet all you wanted is a wild guess.
