Was wondering if you could give an opinion on a dodge I'm working with . I'm at my wits end on an 07 ram 5.7 , only have 1 code 1279 , no start condition , have signal from pcm to tipm , no starter output voltage from tpim (i believe it is c9-pin2). Not much info to go by figured id see if maybe its something common you have run across before . Have good comms and cant seem to find anything else at fault . Tried swapping out the TIPM with a used unit but same outcome . Not sure what direction to go . Love your videos , i've watched pretty much all of them . Thanks

Nice touch with the BFH

Great job, Thanks! I wonder if you can learn from this that if it has 5 volts but only pulling 200ma then it's the secondary processor and if no 5 volts then it's the main processor?
