After "SERVICE MODE" is entered, any trouble codes stored in computer memory will be displayed. ECM codes will be displayed first. If no ECM codes are stored, CRT will display "NO ECM CODES" for about 2 seconds.
After ECM codes have been displayed, BCM codes will be displayed. BCM codes will also be accompanied by "CURRENT" or "HISTORY". "HISTORY" indicates that the failure was not present when last tested, "CURRENT" indicates fault still exists. This type of information assists in diagnosis of intermittent problems. If no BCM codes are present, BCM will display "NO BCM CODES" message. Trouble codes for both ECM and BCM will be displayed in numerical succession of lowest to highest numbered code.
