great question, im ane ECU spirt. )EFI.
what country, nobody ever says, that but gee, the OBD varies buy
COUNTRY!
Ill pretend USA. /Canada.

In the USA the car has OBD2. and you need a scan tool that works
on 2002 cars.
what engine, some engines have different ECU. radical differ..
they had like 3 engines here, other countries 9.

the scan tools connects to the 16pin, OBD2 connector at dash.
i the car is Can-bus. it needs a can-bus tool, all new tools work on canbus but old ones never do. (i have them back to 1995 and know this)
NON comms and tool is ok, not wrong tool . diagnosis.


  1. Pin 16 not at 12vdc, (blown fuse)
  2. ECU dead, 99% of time blown fuse to EFI. test the fuses to all EFI parts. alldata.com wiring shows that.
  3. bad wiring to the DCL connector (rare) or from there to ECU
  4. yes, some crappy tools have no ground on both pin 4 and 5, buy a tool that has 2 pins there. OR it will fail on some cars. seen many POS ELM327 tools that do this horror, get a tool called, INNOVA 3160 and stop guessing, this tool works on all cars.
  5. barrow, rent , or buy or ask any sharp mech top scan car , his tool works.
  6. Fuses that look ok can IN FACT be bad, we never assume they ar good we test them. using either method, OHMS or 12vdc on both sides, is better. see? only the voltage matters, all else punts.
  7. The 3.3l communicates on pin 1 and 2..
pin 2 is PCM/ECU. VPW signalling.
and is not can-bus, yet.
simular to this.

I also have a 2002 issuzu rodeo.the window washer for the front and back is in a hard to get to spot.The reservoir is located under the right wheel frame.In order to get to it you have to unscrew the black covering that is above the right wheel,and you will see the reservoir towards the front a little past the headlight area under that black covering.Just found it today as I have a leak in my reservoir.What a difficult spot they put this in on this car
.hope this helps.Carrie

I am assuming you checked the fuses for the ac /heater first as you mnever said anything about that.. the resistor block and switch removal can be printed out either by the parts store or dealer service..

Have the vehicle scanned for diagnostic trouble codes to see if any have set due to a malfunction.Either a scan tool,or a code reader can access your vehicle's computers.If there is a diagnostic trouble code present,places like All Data online have the diagnostic routes for each trouble code.The diagnostic route,performed properly,will lead to the conclusion of what is malfunctioning.

Hi there, firts you must locate yourself under the vehicle, after that, search for the transmission fluid pan, there you will see two plugs (screws). The one on the bottom its the drain plug, the other its the overfill screw. If you need more information, just send an e-mail (iorek_13@hotmail.com) I had a complete repair manual.
