Cadillac CTS First Generation Forum - 2003 - 2007 Discussion, Reading/Clearing Diagnostic Trouble Codes (DTC) in Cadillac CTS Coupe, Sport Sedan and Sport Wagon Forums; Not quite. They have significance. The beginning of the link I posted explains how a code becomes a history code. ...
Can anyone walk me through resetting the computer after battery went dead. I read one post about and it gave directions on what buttons to push but i'm still not sure which buttons are being talked about.
Press and hold the F1 and F6 buttons simultaneously; the Driver Infomation Center (DIC) will clear and a menu will appear to read and clear DTCs. (Need to confirm this method) I just Did it and it cleared the codes >be advised to hit the large radio botton on the right to complete the action.
I know this is an old thread but just so you know.. On my 03 with NAV I kept trying the NAV & Band buttons and they didn't work... I got frustrated and tried many other combinations... nothing worked... I left it alone.... went back out after cooling off and saw the OTHER NAV button the Nav return button on the bottom of the row! DUH.... Tried Band and the NAV return and BOOM... codes. It's not the regular NAV button.. it's the return. Just a heads up for those saying the Band and Nav buttons don't work.
