How To Use Check Board
- Use the check board when measuring the ECM terminal voltage and resistance.
- Use the connector (B) with part label (A) when measuring the voltage, current and resistance. Connect the connector (C) to the engine control module.CAUTION: If you mistakenly insert a taper pin for measurement into the ECM connector (C), do not use the check board again, otherwise a malfunction may (poor contact, etc.) occur on the vehicle.
CAUTION:
- To prevent damage to the connector, when connecting the connector to ECM, insert the connector straight in until it stops, and while maintaining the position, lock the lever.
- Affix the check board the using tape (A) so that it may not contact the vibrating portion such as engine.
