Adam9066 Posted September 16, 2018 Share Posted September 16, 2018 (edited) I have a 09 cxu613 that will not crank. We checked all the relays and fuses. We put a crank switch on the solenoid and the starter does turn over. I check the ignition switch and had 12 volts on all terminals. When you turn the key you can hear the relays clicking away. We hooked the truck to jpro and the engine ECU does not show. I took a gamble and replaced the chassis harness and the engine harness was replaced in 2013. The driver told me he went to start the truck and it starter for 30 second said dpf fault shut down and would not crank. I'm thinking the ecm might be bad. Anything else I can check? Im guessing a new ecm has to be programmed by the dealer like the dash? I forgot the exact codes but we had a psid 200 and psid 230. One was fmi 4 and the fmi 9 but I forgot which was wich.

Adam9066 Posted September 16, 2018 Author Share Posted September 16, 2018 We took a computer off a 2012 and put it on the 2009 and it fired right up. So we know it's a bad ecm now.
