Here are instructions to check the diagnostic codes so you can do it yourself. Once you get the codes you can reply back to this answer at any time without additional fees and I can tell you the most likely causes. Let me know if you have questions or if there is anything else I can do to help. Thanks.

I need the codes to access the computer. You gave me what the readings should be. Once again, the codes begin: BOMC or EOL8.

Relist: Incomplete answer.
You gave me what the readings should be. I need the codes to input so I can access each item on my computer. Example: BOC5= windshield wipers

Dear Dan

I need the codes to access my comuputer. You gave me what the reads should be. Once again the codes begin: BOM or EOl something. How dare you ask for a tip before the job is done.

Have a nice day

Stephen

Sorry about the delay, I was away from the computer the whole time. In the instructions I sent it shows how to check codes. Step one is the PRESS/HOLD the OFF and WARMER buttons which allows you to enter diagnostic mode which also allows you to check the diagnostic codes. I didn't ask for a tip either, I'm not sure what you are referring to. Let me know if you have questions, thanks.

Dear Dan,


 


When I plug in 1990 cadillac, I need to enter a code, which look like this:


EAGK


BOMC


This code allows me to access the car's computer

My bad. My bad. My mechanic is good and honest, and sometimes he's needs a little help. I did it myself in less than 10 sec. Now she runs as good as she looks.


 


Thank You
