Message: [QUOTE="Luke@MillerPerformance, post: 1024565, member: 12303"] Damn truck is making me work for it. New PCM didn't help. Got a customer to bring me his 6.4 to test on, both PCMs are good. I'm getting a crash course in exactly how the CAN work on a 6.4 is setup. I ran out of time today but did find that I somehow lost the PCM from the network. Resistance check on pins 4 and 11 of the DLC shows too low of resistance, ~120 ohms. Pins 4 and 11 feed from the IC and the PCM. IC has 120 ohm resistor, I forget what the PCM has. Checked the corresponding pins on the smaller of the two PCM connectors and I have an open circuit in the CAN Network. Basically somewhere between the PCM and the DLC I have a connection problem. Must have moved something just enough when I connected the ABS up. Either a broken wire or a connector not in all the way. Also, 6.4 PCMs are cheap, got one for $100. And I got to EFILive a 2013 Cummins, with 08 ECM. Does wicked first gear burnouts at least (customer encouraged haha) [/QUOTE]
