TERMINALS OF ECU
CHECK ECM
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.
