[9c1LTZ]

I've been bugging you guys about my CEL,yet not being able to diagnose the issue. I got an ALDL cable from a friend and downloaded the software from TTS. When ever I try to test the connection or record data it says "no pcm detected. I made sure I have the correct version of the software and the ALDL was functioning. The ALDL pins on the cable being used were the top 2 pins at the right corner on my 95 9c1 OBD1.

HELPHELPHELP.

When mine did that I had a bad fuse. No guarantees but worth a shot.

In which compartment? Under hood or interior? Which fuse?

PCM fuse is under the hood, pretty sure there is 2, but I know that one is labeled PCM/IGN it is a 10 amp. Does the car run and the only problem you are having is logging it?

Com ports set up correctly?

Well since you have a 95 the pins that the connector are going to are wrong, the pin that I use for communication to the PCM is the bottom right, pin M the tan wire. The top two right pins are ground and diagnostic request pins, TTS uses the serial data line for connection/communication to the pcm.

happened to me too. i just used the cable tester and after that it worked. nake sure its at b body, com 3 or 4 (the cable tester tells you what one) and turn the ignition to run. sometime i had to go back and fourth a couple times. also the resistor should b in use, mine made the fuel pump go for about 40 seconds

i have a 9c1 where the douche bag cops cut the wires to the port behind the dask VS propperly removing their stuff, they just went around and cut wires.

that was fun

Thanks to all but I think Mike is right. The ALDL that I have is using 2 top right pins and not top right and bottom right like it should be. I guess I have the wrong ALDL. It was free anyway. I just have to buy the CORRECT one now....
