SOURCE: how much does it cost to purchase a OBD2 scanner tool ?

An obd reader can run you as little as fifty bucks to several hundred I picked up an actron obd 2 from autozone fifty bucks ready to use and has a cd you can download on your computer. It has an erase code setting as well not bad for fifty bucks.

SOURCE: my obd2 isn't getting power what I do?

Check Pin #16 on the Data Link Connector (DLC) for battery voltage. (See Diagram)

If there is no battery voltage present check the fuse marked "OBD II" in the engine compartment fuse block. It is a 10 Amp fuse. If the fuse is good, repair the circuit between the fuse and pin #16 at the DLC.
If battery voltage is present at Pin 16 at the DLC, check for ground at pin 4 on the DLC. If ground is not present, repair the ground circuit between the DLC and Ground G202 located at the left side of the dash.
HINT: the easiest way to check BOTH of these at the same time is to use paper clips plugged into pin #16 and Pin #4 and connect a light bulb between the two. If the light illuminates brightly, power and ground are both OK.
If no problem with power or ground is detected at the DLC, check the Owner's Manual for your code reader.

Why does my truck not communicate with the scanner?


in most other models that have an error trying to connect to an obd2 scanner is there's something wrong in the ground circuit in your vehicle. one has to painstakingly trace those grounds to make sure they're clean/ not corroded... then go from there

Slow start, low rpm, backfires and shuts off


you must RUN the scanner/computer, you can have the manufacturer specification wrong.
The electronic vehicle is complicated, by that reason you can have wrong tune up, PCM+BCM+sensor+ignition coil faulty ,etc
see the diagram attached.

What code scanner is needed for a 1994 olds cutlass supreme 3.1?


1994-1995 was a transition year for car makers with the OBD system.
You can do an internet search for each style plug and see which one you have. The scanner will not connect to the wrong plug.
The OBD2 style is tapered on each side. The plug is under the steering column.

I have a 2004 kia rio cinco that I need to know how to know how to check the codes on, how do I do it? I also need to know how to turn the check engine light off. How do you do it?


If you don't have a code scanner, you can take it to most auto parts stores and have them read. Since you have a post 1996 vehicle you have a OBD2 system and can use about any OBD2 compliant error code scanners. The socket is located to the right of the steering wheel, under the dash lip.

You can reset the check engine light with the code scanner when you read the codes.

OBD2 Link Error comes on when scanner reads.


You may have the wrong code reader. Try another one and see what happens. It could also be a blown fuse, check all your fuses, in particular the one that controls the cigarette lighter.
