I patiently waited for the cables from china to arrive. Per the instructions in rocko350's sig, I made the scanner wire. I tried both eehack and scan9495. Neither worked. It took me a few hours, and 3 laptops (thank god I had 2 old toughbooks running XP sp2 still just laying around) and messing with the drivers to get the cable to install correctly. I bricked the cable on the first toughbook. Im not even sure if I got the cable install right.
I know the connections are good. But what I don't know is if the chip in the USB is good or not.
I've already checked the wiring from the plug under the dash to the PCM, they are good. I checked every 3 wire component connector (except the O2 sensors) from the PCM to the component and they are good- the way in which I tested connectivity was using my meter, setting it to 'beep' and making the connection, listening for a steady beep. The resistance was less than 2, which should be acceptable.
Right now, I don't know if I should hit PCMforless or try the cable from tuneracat.
The car runs. Using the older scan tool and the innovacrap causes the fans to come on so I know the PCM works. The question is if its good or not and I'm not experienced at all in this department.
Can I get some guidance
New (reman) pcm arrived today. Swapped it out. Same problem... Really pissed& discouraged.
This is exactly what the FSM talks/warns about, replacing good parts for no reason.
So either the China cable I made was bad, or I messed the cable up, or as others have posted- self made usb stuff usual just does not work right, or I didn't catch a bad wire when I checked at the DL to the pcm.
Going back to my original problem, the stumble/miss. When I got the car, the seller said he just replaced the EGR. I drove it from North Carolina to Maryland and it ran fine until a few days later.
Where do I go from here- I'm thinking a professionally made cable. This should allow me to see the trouble codes so I can know where to go.
