the data port on my 2002 montero sport not working, so i can't program my remote, is there a fuse that is blown if so where is it located? how do you troubleshoot to find out the problem?
Are you referring to the data link connector under the dash?
This is powered by fuse 5 in the engine compartment it is a 10 amp fuse
There is a description of the fuses.
It is best to check fuses with a test light and check all of them.
I have checked all fuses under hood and under dash, all fuses checks ok, so your answer did not help at all.
and you have no power at the data link connector?
Please give me a call as soon as you get this reply, as the answer you provided did not help as i have already tried the fuses, all fuses checked out good. My number is XXX-XXX-XXXX James.
not at all
We are not allowed to call sorry.
If the connector has no power and that fuse is good the wiring is open at some point.
Have you check the connector for power so we know it is a power isuue and not ground?
i took my vehicle to have remote programmed they could not program it
how would one do that
Do you have a test light?
Ok and you know where the data link connector is correct?
yes under the dash on driver side
ok you need to check it for power. with the test light.
One of the wires should have power
how would i check it for power
with your test light just touch the terminals inside the connector do not jam it in the connector this will spread terminals.
clip of test light hooked to a good ground.
how many terminals will have power?
if none have power what would be my next step?
would have to trace wiring back to fuse block.
ok i'll try this
ok let me know.
The problem may be not that it will not power up but no communication.
the data link connector is wedge shaped,with the wider part at top the power supply will be on the lower right end.
I will keep checking back on here to see what you find.
Thanks for your help, even tho i have tried everything you have told me to no avail, i give up again.
SO does it have power?
And who was trying to program remote? A lot of aftermarket equipment will not work
I have a key/remote programmer it will program some vehicles but will not go thru on some. Even same model.
Some problems just cant be solved without seeing the vehicle. sorry I will forward you to customer service
