I have a 99 STS and a 2001 ETC. I need to know how to access the computer on both of these cars. Thanks for your help. Doug J.

You mean getting the codes? Hold down.... AC Off, and the passenger heat up button for several seconds. Leas that's what I think it is. You can also go to Autozone, they'll pull codes for free.

Can't help with the ETC, but your STS should be the same as my 1998 STS.

You will use the 3 buttons located to the right of the Driver Information Center (DIC) to activate and respond to the OBD prompts on the DIC.

INFO DOWN or INFO UP = manual toggle

Ignition ON, acknowledge any warning messages, press ON/OFF and INFO UP together for 2 to 3 seconds (everything in front of you lights up for 4 or 5 seconds,) then you will see:

Display shows "ALL?"

Answering YES will display "ALL CODES?"
Answering YES will run automatic test sequence and display codes, if any. Systems and codes will scroll faster than I am able to read them and write them; not to worry.
"ALL CLEAR CODES?" will display at the end of the automatic test. If you are satisfied you have the information you need, answer YES to erase all error codes.

Answerering "ALL?" with INFO DOWN will toggle systems test manually in order.
Answer "ALL?" with INFO UP will toggle system test manually in reverse order.

Press INFO RESET to restart DIC to "ALL?"

Ignition OFF to get out.
