04 xl7 would'nt start had it jumped. SYS

actually there are no limits, skills max.and plasma cutters etc.
ever seen a ford pinto body on a huge 4wd truck chassis.frame
and more google it or you tube it.
only limits are laws, on the road. really.
we can not guess what YOU can do ever.
my guess you meant PnP, plug and pray?

manual starts 5-53 on link page 236
Page 239 shows a fuse named day time running lamp 2
Page 240 has a fuse daytime running lamps

XL-7 (dash 7?)
"engine not starting" sure... but that is step 2, not 1.
but you failed to say does it crank robustly
yes./no?
if NO, those silly dash messages are a waste of time.

ever herd of jumper cable starts, or calling AAA and asking the man do jump start your dead battery?
are headlights dim?
charge your dead battery with a charger?
or replace it with borrowed charged battery?
or if dischanged, and you charge it and it starts now,does the alternator work> and give you, 13.3v to 15v battery voltage
no? then dont drive too far or this will strand you. as battery dies again,



is the battery good, 12.6vdc rested and 11v min, cranking?
if the battery gets too weak, it cranks too slow and voltage falls too much and the ECU/PCM/BCM (brains) will fail and dump lots of codes.
one code is low battery.
the FSM book covers all code, buy one or look at alldata.com?

0101 =
Lost Communication With TCM 0073 (can-bus network failure)
The module setting the DTC has attempted to establish communications on the serial data circuits more than 3 times. BCM, DRR, HVSM, PPS, PSCM, Radio, RCDLR, ROS, RSA

It has spark and fuel when the fuse is blown too?

there is a DTC error stored, in the ECU. (scan tools show this)
there is a car puter, error, message that really means
the gas tank is not holding air pressure.."EVAP sys"
and 99% of the time, that is "a loose gas cap"
it can take many driving cycle to clear this code.
or 1second with any scan tool, even a $30 tool.

Might need to check the main circuits for a blown fuse or fuseable link.
There is a fuse wire between the alternator and battery.

jumping the car backwards has likely blown fuses or burnt out components of the system, you need the dealer on this.

You probably just blew a 50 cent fuse.

Test charging sys.and test for current draw,may also be a tracking sys.
