How to access trouble code

year vehicle manufactured? if 1996 & later, OBDII scanner to be plugged into a port (typically, should be near the steering column, under the dash).
older models may have OBDI (no standard location of port) scanner specific to the make of the vehicle. search the web, on how to read manually (or without scanner) the code by counting the number of blinks of the MIL (malfunction Indicator light) (aka check engine, or service engine soon).

Check pin number 16 of the OBD 2 diagnostic connector, it should have 12 volts, if not the port will not power up the code reader or scanner. See diagram below.

Want to know the location of the service port to scan the check engine light to pull out the code

It should be right above the pedals, under the dash. Use a flashlight and you should see it.

How do i read the trouble code on a 94 passport without a scanner

This is not possible without an error code reader Unless you have check engine or service engine light Then you can hotwire the port for connecting scanner
and it will flash the code to you using the check engine light on dash
But its quicker to use a reader.
Different car models you can get to flash codes to you contact you car dealer to enquire about it.

2003 Saturn LW300 3.0V6 engine light is on. Hooked up a code reader and the reader was not able to ''link up'', I checked connections and tried several more times with no results. Are there any other...

I have this model Saturn (2003 LW300), and bought a code reader off Ebay. Make sure it is a compatible "OBD2" type, and plug is seated firmly with ignition switch off. Then turn on ignition without starting car. Press "Enter" or something on reader to start it and it should work.

Service engine light soon on for serveic how do i turn it off

You can go to any auto parts store, ask to barrow an OBD-II Code reader. Plug it into your cars computer data port (Usually on the dashboard, on the drivers side, close to the lower portion of the dash) and push erase.
However, you should find out what the computer is telling you first, and/or fix the problem. Engine service lights, run on a circuit that only completes itself once every 20-30 times you start your car. This means, if you were to just erase the engine code, the light will go off, but will just turn back on eventually.

The engine light could be on for an unrelated reason. Most major auto parts stores will scan and clear codes for free or have a loaner you can use on site. The reader plugs into a port under the dash on the drivers' side....get the code number, then clear it with the reader. If the same code comes back, post it here or Google it for additional help

Engine warning light stays on my suzuki grand vitara what does this mean

It means there is a fault stored in the computer memory that needs to be identified and fixed.
Have the code read or take it to advance auto and they will lend you the reader so you can plug into the diagnostic port under the dash and read the code.
The code reader can then be used to reset the check engine light and turn it off.

Service engine code indicates EGR valve.

You could have a restriction in the egr ports. remove the valve. Plug the holes, start engine. 1 hole will be blowing out exhaust, the other will have large vacuum.
