Retrieving Codes

When Mode II is accessed (engine NOT running), codes stored in ECU memory will be flashed by CHECK ENGINE light and red LED on side of ECU. A long flash (.6 second) will indicate tens column digit. Short flashes (.3 second) will indicate ones column digit. For example: 3 long flashes followed by 5 flashes of red LED (or CHECK ENGINE light) indicate a Code 35.
