How do you access the codes on a 1994 Honda ac ord station wagon?
If you are referring to the diagnostic trouble codes (DTC), you can go to your public library and check out a Haynes or Chilton's Repair Manual for your vehicle. Chapter 6 in either book will have instructions on how to retrieve the codes, what the codes mean, and how to fix/repair/replace the component(s).
To pull trouble codes you have no scanner which prongs do you jump and after you retrive the codes can you look up the codes with out a repair manual?
If your vehicle is 1995 or later, you need a scan tool to retrieve the codes. If it is 1994 or earlier, you can manually retrieve the codes by jumping the pins. No way in the world to know which pins to jump or what the trouble code(s) mean since you don't give a make or model vehicle. Regardless, detailed instructions and full list of trouble codes would be too much to include here. A Chilton or Haynes repair manual is your best resort. If you don't want to buy a manual, try your local public library.
