2000 Deville Driver Information Center

Because I have a "check engine soon" light, I attempted to access the DIC to read the trouble code. When I simultaneously depress the info up and on/off buttons for seconds nothing happens. Not able to enter the system? Has anyone had this experience? Is there a way to reactive the DIC?

You have to hold both buttons down at the same time for maybe 5 seconds to get into diagnostics.

DTC display; 1998-2004 Seville and 2000-2005 Deville

by JimD

Use the 3 switches located to the right of the Driver Information Center (DIC) to activate and respond to the OBD prompts on the DIC.

ON/OFF = YES

INFO RESET = NO

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 clear/erase all error codes.

Answering "ALL?" with INFO DOWN will toggle systems test manually in order.

Answering "ALL?" with INFO UP will toggle system test manually in reverse order.

Press INFO RESET to reset DIC to "ALL?" to start again.

Ignition OFF to exit.

We have had times where a member could not access the diagnostics to access the codes

While this will remove the code, try disconnecting the negative connection at the battery for 5 seconds and then reattaching and letting the system reset. Then try to access the codes to see if the system allows you access

If the code is persistent it will come back.

No other suggestions, usually disconnecting the battery and resetting the system fixes that

I will just say one thing, MAKE SURE, you are pressing the correct buttons and not assuming that you are pushing the correct buttons

Re-read the directions

JimD will pop by later, I am sure he will provide some help

Maybe try it with the car running and with the car not running but key ON. Should be able to do it both ways but its worth a try.

I would disconnect the battery for longer. 5 minutes or more. Other GM cars I have require 15 or 30 minute intervals for the computer to relearn sensor settings after cleaning or replacing.

Does the car run fine?

Does disconnecting the battery automatically reset the DIC? Is resetting another process?

Disconnecting the battery as I said removes power from the PCM and erases volitle memory. On restart the system goes through a relearn for emissions, etc, but it should have opened up your diagnostics, as I noted sometimes we have seen members NOT be able to get into their diags and disconnecting the battery all of a sudden permits it.

Disconnecting the battery is the ultimate way to "reboot / reset" your PCM to start it over.

Do the buttons you are pushing work independently? Meaning could there be a problem with the buttons? Are you pushing them hard enough or are they binding?

You might try to read the codes via a code reader, maybe you have a network problem

Does everything work, steering wheel buttons, hvac, etc?

The car runs great. I have additional information. I noticed that the timer was in the off position and decided to see if the on/off button would turn the timer on. Pressing the on/off button would NOT turn the timer on. Could this be the problem? If so can the on/off button be replaced?

That is what I was getting at in my post just above, you may have a problem with one of those buttons......

This maybe a duplicate reply. I just tried to turn on the timer using the on/off button. Pressing the button did NOT turn the timer on. Could this be the problem? Can the button be replaced?

I have tested all the other buttons and everything seems to be working.

Like I said above, you MAY have a problem with a button

According to what you are saying it appears that you DO have a problem with the ON/OFF button, if the ON OFF button has NO function. Personally I thought the ON OFF button turned the INFORMATION center ON or OFF.

Does that button have NO function at all? If so, that is probably your problem, you may need a new button panel from a scrap yard or from the dealer. But I would be visiting the scrap yard.

This appears to be the button pad you are having a problem with, I'd call the dealer or visit a junk yard. But first I would take apart the button and see if I can repair it or if the connector has been detached

I just tried mine today. It's a 2001 with the same button as Fishers picture above.

You should be able to easily scroll thru the cluster display using the Info ^ and v button. Things like oil life, trans life, miles to empty, timer, etc.
