Dual Led - 5 Modes: Notes

The self-diagnostic system is capable of detecting ECCS malfunctions and storing trouble codes. Since even intermittent codes are stored, all codes are available for interpretation unless codes have been cleared or ignition has been cycled on-off 50 times since the malfunction last occurred.

Self-diagnostic system will be operated in one of 5 modes. Modes are manually changed using screwdriver through access port on ECU. To enter or change mode, turn screwdriver fully clockwise. Inspection lights will begin to flash. When desired mode has been entered, turn screwdriver fully counterclockwise. Red LED and Green LED perform different functions in different modes.
