Turn the ignition switch to the ON position.
Check that the voltage between terminal VC1 and ground is 5 V.
HINT:

For the terminal arrangement of the engine ECU (See TERMINALS OF ECM ).

While turning the crankshaft pulley by hand, measure the voltage between each terminal. Check that the voltage changes between the Hi range and Lo range shown in the table below.
