WJ jeep USA.
fuse blown
or caused by trailer wiring rear, hitch, all mangled common
or past collision damged
front park lamps dead to or side lamps park dead/??????????????
only takes eyeball to see that.
or scan the PCM it will tell you why.
the service manual has the schematics for all that,
brakes + tail/park but blinks ok?
beside bad wiring, (I have A reAL WJ MANUALS ALL)
THE FUSE 6 IS BLOW
OR OFF F6 THE RELAY PARK IS BAD.
THE BCM BRAIN RUNS THE PARK RELAY TOTALY
SO BCM FUSES MUST NOT BLOWN, Just test all fuses. ?
BCM fuses are F7, f22, and f28, not blown./
the BCM must communicate on the network or fails
PCI bus is Jeeps name
if anything trashes this bus vast things fail.
if BCM is dead vast things fail over 25, and endless seeming list
not told you what does work? (telling only bad things only makes the job 10 x more hard.
scan and it tells you what is dead in 5min work. on most cars./.
