The ELM327 on-board diagnostic tool is somehow interfering with the operation/communication of the CAN bUS (CANBUS) system. Might be the computer doesn't not recognize it and simply goes haywire. Plugging vehicle monitoring gadgets into the on-board diagnostic port has caused a variety of issues for other members. Perchance the tool is better suited or compatible with a different vehicle.
