Trouble Code Output & Code Definitions

After the initial LED segment check, ECM trouble codes stored in the computer will be displayed on the Fuel Data Center (FDC). Codes will be prefixed with an "E" (ECM) or "F" (BCM) to indicate which computer detected the malfunction. Record all trouble codes displayed. After all trouble codes have been displayed, or there are no trouble codes in the system, a ".7.0" will appear in the display, indicating system is ready for further tests.
