PRECAUTIONS

Never reverse polarity of battery terminals.

Install only parts specified for a vehicle.

Before replacing the control unit, check the input and output and
functions of the component parts.

Do not apply excessive force when disconnecting a connector.

If a connector is installed by tightening bolts, loosen bolt mount-
ing it, then take it out by hand.

Before installing a connector, make sure the terminal is not bent
or damaged, and then correctly connect it.
When installing a connector by tightening bolts, fix it by tighten-
ing the mounting bolt until the painted projection of the connec-
tor becomes even with the surface.
