The data link connector uses the same fuse as the cigarette lighter socket. Does that work? Check your fuses.

Abs lights coming on 03 ford windstar

Go to your friendly auto parts store where they provide a complementary OBDII scan and identify the most likely defective component. The advance scan tools read ABS faults. Suspect a wheel speed sensor or plug connection!

Hope this helps>

03 Jeep Liberty passenger window down rained very hard floor flooded 5 gallons of water No start pulled carpet checked fuses relays in dash under hood no start start with starting fluid but dies mike

well, like all cars .
get it dry, first. my guess air bags at seat connectors will fail. too.
1: check fuses next.
2: then scan it. connect the scan tool and addresses all DTC errors.
if you dont have a shop, with tools tow it to one with that.
any ASE shop , check it and tell you how bad it is, and cures.
flooded cars are not easy to fix and love to REPEAT fail.

I have an 03 moutaineer I replaced the battery but it won't roll over it makes a click noise and that's i . The last I bought from said it would start but wouldn't stay running.

If all you hear is a click that is the starting solenoid. And if your battery is new and well connected, and the car does not crank,, then I would say the starter motor is no good.

How do you install a fuel gauge on a 03 ford focus 2.0

Screw your fuel pressure gauge hose onto
the fuel rail schrader valve

You may have fuel pressure on scan tool data

You would have to connect to the DLC under the
dash & see what shows up

2002 rodeo is my obd ground bad my ecu wont communicate and horn wont blow but fuse is good

great question, im ane ECU spirt. )EFI.
what country, nobody ever says, that but gee, the OBD varies buy
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. 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.

top right photos

there you go, you tool must have VPW support on pin 2.

03 Ford Explorer w/ V6 engine. Will not communicate with state of CT Emissions computer but scan tools work fine without any codes. Mechanic has has check wiring at OBDII connector which is good and is...

NO it's not bad. If any scan tool reads it and the mechanics scan tool wont' then there is a problem with the mechanics scan tool. Some scan tools require a different chip in them to read different cars. Try another mechanic.

Keyless entry wont work 2002 chevy s10

The only way to program them is with a scan tool so you'll need to visit your local dealer to have it done. Here is how it is done.

  1. Install a scan tool.
  2. Use the scan tool in order to access programming: Vehicle Control System/Computer Integrating System/Module Setup/BCM/Program Key Fobs.
  3. Press the START soft key on the scan tool. Important: The scan tool must stay connected until all of the transmitters are programmed.
  4. Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of 5-10 seconds, the scan tool will indicate that the transmitter is programmed.
  5. Repeat the previous step in order to program up to 4 transmitters.
  6. Remove the scan tool.
  7. Operate the transmitter functions in order to verify correct system operation.

Power windows does not work in my 2002 moutaineer there is no other electrical problems how do I fix this

If they all don't work and you checked the fuse and it's good it is the window switch. Pretty easy fix, get a door panel tool at a parts store, unscrew all of the screws for the door pull, door handle cover, and what ever else is screwed on. Use the door panel tool to pop off the cover and the switch will then be accessible.

Abs light on, 2004 moutaineer

You most probably have a bad speed sensor on one wheel if it is intemitent try unpluging each on and repluging them, sometimes just a bad connector, If this doesn't help get someone to scan the codes for you and it will tell you which sensor is the problem. Keep in mind that until you fix this you can not depend on your ABS system. Normal braking should be fine though.
