I have a 03 Dodge Ram 2500 gas Hemi with 80000 Kms. The engine light came on and I put it on the OBD2 reader and it said that the Error Code was P0352 Primary and Secondary ignition curcuit #2. I changed #2 & #4 ignition coil and also changed all the plugs and the wires. I put it back on the OBD2 reader and resetted but the engine light is still on. Truck seem to still work good but now it is idling rough and it seems like it is misfiring. I did an AC hertz test on terminal connection at coil with a rating of 30 is very high compared to 3 in adjacent cylinder.

Does someone happen to have the ignition wiring diamgram?
I cannot do a continuity test between the PCM and the Coil connector without a diagram for proper terminal testing connection.

Someone has told me that it might be the PCM, would this be a likely problem?

 

I don't know anything to help you, I just had similar issues and I had to change the ECM / PCM and when I picked up the truck nothing had improved and now I have more issues. I would like to hear if you get yours figured out
