1995 Pontiac Grand Prix 6 cyl Front Wheel Drive Automatic 53000 miles
I have a Haynes repair manual and was trying to diagnois a problem with a hesitation condition at around 2100 rpm and from 45 mph and higher when giving pressing the pedal down slightly. In the manual it says that a 12-pin connector is a ALDL and a 16-pin is the OBD-II and my vehicle is the 12-pin.
Manual says to jump the " A" (ground) and " B" (Diagnostic terminal) terminals which the diagram shows them to be the 1st and 2nd from the right top connectors, which should flash the codes via the " Check Engine" light but nothing happend.
I removed the connector to check the wiring and " B" terminal has no wire and there were only three. There is one " Black" wire, one " White" wire and one " Green" wire only to this connector.
My question is can I install a jumper wire between two of these colored wires to receive the flash codes on the dashboard?
