Adjustment & Inspection: Notes

CAUTION: Never connect battery in reverse polarity. MPFI control unit will be destroyed instantly. Fuel injector and other parts will be damaged also. DO NOT disconnect battery terminals while engine is running. A large counter voltage will be generated in alternator which may damage electronic parts such as MPFI control unit. Before disconnecting connectors of each sensor or MPFI control unit, be sure to turn ignition off, or MPFI control unit may be damaged. When installing radio antenna, ensure that it is as far away from control unit as possible.
