Clearing Diagnostic Trouble Codes

Selecting reset codes will result in the message "CLEAR ECM CODES?" or "CLEAR BCM CODES?" depending which system was being tested. At this point the following action may be taken:

1. Pressing the "OFF" button will stop the test selection process and return the display to the next available test type for the selected system.
2. Pressing the "LO" fan button will display the next test type available.
3. Pressing the "HI" fan button will select "CLEAR CODES". A message "ECM CODES CLEARED" or "BCM CODES CLEARED" will appear to indicate those codes have been cleared from memory.
4. Pressing "BI-LEV" will exit diagnostics.
