After the "Service Mode" is entered any trouble codes stored in the computer memory will be displayed. ECM codes will be displayed first. If no ECM codes are stored, the CRT will display "NO ECM CODES" for approximately 2 seconds.

After the ECM codes have been displayed the 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 the fault still exists. This type of information helps in the diagnosis of intermittent problems. If no BCM codes are present, the BCM will display the "NO BCM CODES" message. Trouble codes for both the ECM and BCM will be displayed in numerical succession of lowest too highest numbered code.
