so what are the symptoms.?????????????????
what transmission, A/T or M/T?
you get on the dirt. and shift to 4Hi or 4low (its not for DRY pavement) so... AWD started in 2004, so is not AWD. but PT.
called Part time four wheel drive.
are you getting ready for snow , that it? do say so, as telling the job puts us on the same page...
and 4wd does not engage?
this system is just Part time 4wd,. and is for ice roads or dirt only.
the first test is the transfer case not front axle.
when you select 4HI the gear dogs in the transfer case lock.
and not power goes to the front prop shaft,
with all 4 wheels on jack stands this can be felt key off.
or running in 4wd.
key off , and A/T in PARK or 5speed stick in say REVERSE
you can not turn the front prop shaft by hand, in 4H wheels off ground, that means the transfer case is in fact in 4hi.
Ok we now have POWER To the front axle. (following me;/??)
so the front axle locks.
if the front , fails to lock, up, at spec pressure then the part 18 is bad (spec is 4.25 PSI)exactly.http://www.fixkick.com/axles/04lock.JPG
if on the other hand the pressure is low, then this is bad
part 25 pump i s bad.
or is the only symptoms just the dash light.
as driving on pavement dry, (no ice) its normal for the dash light to fail. after all you dont belong in 4wd now. lacking ice or dirt.
but if you jack car up in air, sure the light must come one.
the light dont come on until the transfer case fully engages.
and cant if on dry ground and it binds up, as ALL DO.
get on dirt.
shift to 4wd, going dead slow, 1/2"mph slowest possible speed.
this saves DOG DAMAGE. in the box.http://www.fixkick.com/part-time-test.html#Suzuki_PT
no,sorry, the PCM has Zero to do with the manual transfer case.
please say , what fails (besides the useless dash light)
what are you doing?
where is car, what surface are the tires touching?>???
do not drive this car on dry pavement (means no ice)
in PT 4wd.
its not for that. sell car buy 2004 with AWD.
if you know all that, as the operators guide says.
then do the prop shaft test .wheels off ground.
and say what transmission you got here,
i have 4 cars like this all are 5 speed box.
see the dogs here.
see red arrow. see words weak.?http://www.fixkick.com/tranny/xfr-case/XFRCASEGUTS.jpg
when you shift to 4H, this dog engages and the chain moves.
and the front prop shaft moves with full power.
that is test one, engage this dog and test.
the dogs are the small teeth on gear #29
