1. Checking connector terminals
Check that the battery voltage is 10 V or higher. Then, while referring to the circuit diagram, check each connector
of the connector ①(13-pin, natural) and the connector ②(12-pin, black) connected to the ECU in accordance with
the following table using a multimeter.
If any terminal is out of specification, perform the applicable troubleshooting shown in the table.
