How do I perform the ECU diagnostic?

    The service manual recommends this method, although the one below is quicker.

    You can also use a one inch electrical wire (I always keep one in my ashtray) and connect the ends to pins 8 and 9 on the service/consult connector for three seconds. That is exactly the same thing as turning the potentiometer on the ECU...

    The connector is located on the left side under the dashboard, right by the hood opener.

    The connector looks like this and just connect the two arrows (IGN and CHK) for three seconds... & the check engine light will flash the error codes (if any).
