ECM frozen
The U0100 error codes from the combination meter says the ECM is not communicating. Thought about an immobilizer issue but when I interrogate it, I get immobilizer 'SET' condition then when I turn the key off and back on, it goes to 'UNSET' and still can't talk to ECM. This is the third ECM. The pins of the ECM don't agree with any docs I have. This car had a shorted CAN bus before I changed several modules and no one knows why. I am suspicious of a wiring or connector pin problem.

ECM pins
I need to remove the backshells to see the wires (haven't figured that out yet, don't want to break them). Should they follow the 2007 color coding (which I have)?

When I remove the connectors and look at the pins, they are not the same number of rows as shown in the doc, and the number of pins per row is also different. I went through and logged each pin with ignition off and on, then tried to correlate it to the connector pin-signal drawing and couldn't get a correlation.
Sorry I was gone for a few days and am late in replying. |

I just realized that you are not the original poster. The OP had a 2007. Your 2013 is a completely different ECM.
