Selecting Clear Codes

WARNING: This page is about a different car, the 1998 Cadillac Eldorado and 1998 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.

Selecting "CLEAR CODES?" test will result in "CODES CLEAR" message being displayed with selected system name for 3 seconds, indicating all stored DTCs have been erased from memory. After 3 seconds, display will automatically return to next available test type level. After a DTC has been cleared, make a complete ignition cycle and test drive vehicle (if possible). Ensure DTCs do not reset.
