AAA guys dont fix car, they rescue them....
the door lock system is broken
you have 2 choices. may be 3
- Take it to any ASE mech, and he fixes,it.
- Get the FSM from JEEP open the page on DOORS, and do the tests shown there.
- Using SAME FSM defeat the DOOR system. using keys.
#3 may just be a fuse pull, ill look that up now for you. ....lets see...
what id do.
id check all fuse first for blown, with an ohmmeter, 0=good, infinity = bad.
then id pull all the door relays. in the main junction box.
is the battery drain gone (i use and ammeter to find that truth)
THE BCM (body control module ) runs the locks, so you can just
pull its fuses.. or other things die.
keep in mind that door locks are alive , keys in pocket.
so that begs the question, is the BCM messing up (or relays stuck)
or is the BCM being told to open a door, full time ?
id connect any scan tool to the OBD2 conn. and see if there are fault codes. (like relay stuck door, etc)
stuck switch for doors."called door lock switch mux"
The BCM has many relay that it controls, pull them all and see
which one is causing the DRAIN, key off
and work backwards from there.
the BCM has RKE data line, this is the remote key receiver.
if it goes nuts it might seen door commands to the BCM full time.
so unplug it, to see if the commands end.
its called the RKEM (m for module)
the problem focus is the BCM is the brain that runs it all.
it has inputs and outputs.
the brain (processor) can have a bad input (switch or RKE)
or the output can stick (prime target door relays)
that is it .
i cant find the JB B+ hot feed, drawing, there are over 50 pages on this JB. a real FSM would win here. to find the door power actual feed .
such is life, in newer complex cars....
