TERMINALS OF ECU CHECK ECM (for 1UR-FE)
 HINT: The
standard voltage, resistance and waveform between each pair of the ECM
terminals is shown in the table below. The appropriate conditions for
checking each pair of the terminals is also indicated. The result of
checks should be compared with the standard voltage, resistance and
waveform for each pair of the terminals as displayed in the Specified
Condition column. The illustration above can be used as a reference to
identify the ECM terminal locations. |
