I got it by counting flashes. I believe it has something to do with my AC not working, when I read the link for trouble shooting the DTC 26, the section that applies to my situation is that when I ground the ALDL A to B, coolant fan kicks on instantly. Then it tells me to remove the ALDL ground and turn on the car and run the AC. I know my AC doesn't run, my compressor doesn't kick on. Therefore, the trouble shooting guide says to check for grounds. I have a digital multi-meter, I wanted to know if there is a way to check the plug holes that my AC relay plugs into with the multimeter? Otherwise, how do you check a relay for resistance. What prongs do I test out of the 4? In addition, is it true that if I get to my PCM and try to take a look at the wiring and unplug the connectors will I have to go to the dealership and get it reprogrammed? I am a little hesitant about messing with the PCM if that is the case. How far in handling the PCM can I go without having to reprogram it?
