Dual Led System (5 Modes)

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