Pinout Values and Diagnostic Parameters

2GR-FSE ENGINE CONTROL SYSTEM: SFI SYSTEM: TERMINALS OF ECM





NOTICE:
* The ECM has waterproof connectors. Therefore, voltage or waveforms cannot be checked with the connectors connected to the vehicle.
* The standard normal voltage (reference values) between each pair of the ECM terminals is shown in the table below. The appropriate conditions for checking each pair of the terminals are also indicated. The result of checks should be compared with the standard normal voltage for that pair of terminals, displayed in the Specified Condition column. The illustration above can be used as a reference to identify the ECM terminal locations.

























HINT
*: The ECM terminal voltage is constant regardless of the output voltage from the sensor.
