HOW TO "ENTER" DIAGNOSTIC MODE


To enter diagnostic mode, proceed as follows:
Turn ignition "ON." Engine can be either OFF or RUNNING.
Depress the "ON/OFF" button and the "UP ARROW" end of the info button on the driver information center simultaneously for a few seconds.
All the dashboard lights will illuminate, including the segments of the DIC display. You are then presented with text.
You can cycle through different questions using the UP and DOWN arrows on the info button.


HOW TO "EXIT" DIAGNOSTIC MODE


To exit the diagnostic mode anytime during the test turn the ignition switch "OFF." Additional information on Trouble Codes and Diagnostic Procedures specific to the 2000 OBD-II Cadillacs (http://myweb.accessus.net/~090/dtcobd2.html)

You can't do that on a CTS.
You have to have a scan tool.
Trouble codes are 5 digits and can't be flashed anymore since the first character is a letter and the DIC do it yourself diagnostics are not set up on that model.
Sorry.

This procedure won't work on your 2003 Cadillac CTS. For the non-nav 2003 CTS, hold F1 and F6 until all the interior lights turn on. You can now access and clear all error codes set by any of the modules in the CTS. To exit this mode, you need to cycle the ignition.
