Entering Self-Diagnostics
- Turn ignition switch to "ON" position. Use a screwdriver to turn ECU diagnostic mode selector fully clockwise.
- Wait for inspection lights to begin flashing. At this time, inspection lights will flash the mode options (i.e. 2 flashes for Mode 2, etc.). As soon as inspection light flashes the desired mode number (3 flashes for Mode 3), immediately turn mode selector off.
- If the mode selector is kept in the "ON" position, the mode selections will continuously cycle (Mode 1 to Mode 2 up to Mode 5, then cycles to Mode 1, etc.) and the process will continue. This will not erase the memory.
