I still need to get readouts for my car.

The trick of shorting out the code reading plug simply doesn't work on this car, this year, this engine.

The GM code reader reads every car/year but this one.

What is the minimum equipment needed to read the error codes?

What is the actual brand and model of code reader (and source for it) that can/will actually read the codes for this car this year this engine?

There is NO 'autozone' here in Canada, and I don't believe anyone in this entire country will read the codes for me without charging an arm and a leg.
