Memory Erase
Stored memory will be erased if battery is disconnected or Mode 4 is selected after Mode 3 has been accessed. However, if mode selector switch is turned fully clockwise (on-off switch turned to "ON" position for Pathfinder & Pickup), diagnostic modes will continue to cycle, from Mode 1 to 5, and will keep cycling in the same order, until a certain mode is selected. This does not erase the stored memory.
