not true box is under hood now. look there first.
the operator guide tells this...
all 4 exterior lamps dead, in HAZ mode but not TURN mode?
is the cluster dead?, or just the haz green icon lamps dead in cluster>. see it blink there?
the fuse is invisible and fully electronic on this car.
tell full symptoms, and win.
and scan it.
Long answer: (no fuses? ,well that is not true, in total)
I guess you didn't open the hood, and see all fuses moved there in 2007, in the new TIPM, total integrated power module. there are tons fuse there, , ill review the system and i own one, and full docs on it, and more)
please tell us the symptoms. first,? not a guess first, and search of parts that don't exist.
tell is what works right and what not not , THE WHOLE OF CAR MATTERS. are all pod switches dead?
car runs and drives ok?
at night runs ok with bright head lights??
do the Turn blinkers work?, and wipers, and all other features?
only hazards dead? just that ????
the 2007 Jeeps radically changed on this year.
sorry 2, it's not the pcm bad for engine.
the car has other computers, not just one and they network now.
yes check all fuses first, as some fuses , that may seem unrelated
blown may cause network errors.
the TIPM fuse, and others. The TIPM is a computer as is the switch bank.,
THE FLOW: (end to end)
the haz button on the Pod switch bank, sends a serial signal (data command) to the TIPM , via the CAN-bus network
we must scan the pCm to see those errors. on that bus.
the pod needs power as does the TIPM needs power
that is why I ask do other things fail , or not.
if the haz button worked, (transmitted ok) the cluster would flash
it listens on the can-bus for the same transmissions.
this allows it to flash the cluster lamp, (independent of TIPM)
so does the dash cluster lamps flash? and click?
If the cluster fails to flash that is because, the network transmitted signal failed.
if does flash, in the custer but not 4 lamps on 4 corner of the car that means the TIPM failed to receive this can-bus transmitted signal. or the TIMP has problems..
If turns work, and not HAZ at this point id suspect bad TIMP
or some very odd CAN-BUS errors
this is why we....
i scan first. to see if there are communication errors
or error from the TIPM.
The haz module can be dead, if Fuse M20, is blown.
why not test all fuses, and avoid having to learn all this????
as seen below,
then M13 if blink fail. (only)
so if blinks are good, Turns
and haz fails ONLY, then fuse m20 is bad.
if not, bad, (including cluster dead for same)
then the TIPM programming is bad, or some strange, communications lost here.
M20 fuse runs the switch bank, that would kill all power on all switches on the switch bank , including HAZ
and M20 runs the cluster ALSO, killing it dead. if m20 blows.
m20 runs the computer in the cluster. (one more computer)
now the TIPM , it has one fuse, and if blown kills a vast array of feature, all from it.
fuse J31, powers the TIPM if this fuses blows the TIPM goes dead. and vast things fail, over more that 25 things, (im not listing them)
That is the reason for no haz fuse. is because there is no has fuse just for HAZ. (but the m20 runs many things,not just HAZ)
the TIPM main power, connects to a highpowered transistor driver
that drives, the 4 lamps. 4 corners of car DIRECTLY.
be that turns or haz, same electronic drivers for 2 features.
using no fuses. this is because the magic drivers have electronic roll back, circuits , effectually acting as electronic fuses,automatically
.same with wipers
The FSM explains all this. (book for car from jeep)
see the red words here,its a quote.
full DC distribution here, all fuses. 2008 JK http://jeepdied.com/pdf%20and%20more/TIPM/index.html
so what to do.?
1:next time tell if turn sigs work and state that car drives ok at night with head lights on, all other things work.?
2: check all fuses under hood, in the TIPM. (old name PDC)
3: scan PCM. using a modern scan tool, all scanners work.
then report all DTC errors.
easy as 1,2,3. no?
for the features you have opted, are all dead/?
min has ESP, does your ESP work or is it dead too.
when you turn on parking lights, my esp and haz glow.
when push the esp the cluster, shows, skidding car ICON.
does yours.? aka, bank switch, other name for pod.
full drawning of below is on linked page above. look there.
