VP Commodore Engine Trouble Codes

Here is a list of ECU error codes for the VP commodore. These are read by shorting the black, and black/white wires that go to the ALDL connector under the dash near the glove box. Short these wires, turn the ignition on and the check engine light will flash the code.
