Selecting Clear Codes

Selecting "CLEAR CODES?" test will result in "CODES CLEAR" message being displayed with selected system name for 3 seconds, indicating all stored trouble codes have been erased from memory. After 3 seconds, display will automatically return to next available test type level (i.e., PCM SNAPSHOT?).

After a code has been cleared, make a complete ignition cycle and possibly a test drive. Ensure code does not reset.
