DTC PO700 came up on my MIL so I paid a shop $110 to pull TCM codes. They got P0602 (control module programming error) & P0613r to (TCM internal fault) They wanted another $100/hr to trace wires, test sensors, etc. to 'try' to find out what the problem is and what caused it. Could take 1-4 hrs to diagnose it, 'IF' they could! Dealer said they won't touch it unless I pay them $110 to pull the TCM codes themselves and then $110 hr to 'try' to diagnose it. I thinking about ordering an ECM, installing myself and Pray it fixes the problem! Any advice is GREATLY appreciated!
Did you ever order a new ECM? If so, where did you get it from and did it solve your problem? I need a new ECM too, but after reading tons of bad reviews about various companies that sell re-manufactured units, I don't know which one to trust, if any! Initially PO700 came up on the MIL, so I took it to a shop and paid $110 for the guy to pull the TCM codes (PO602, PO613) They wanted $100/hr to trace wires, check sensors, etc. to further dx. it. Said it could take 2-3+ hrs to 'try to' figure out what went wrong and why. > The dealer said they will need to re-pull codes @$110 and also trace wires, test sensors... > I know by the time either of them are through with me, I'll be out a couple grand minimum! My vehicle only has 35K miles and has had all dealer service as recommended... argh! I'm thinking about ordering a rebuilt ECM and hoping it'll fix the problem. Hopefully, whatever caused my current ECM to fail won't screw up the new one, but with my luck, it surely will! I wish someone could test my ECM to see if it's even bad... God I miss the old days when cars weren't controlled by computers!
