Hi,
I have a problem with my Corvette, the car arrived on a tow truck, no communication with TCM. I checked the power supply, grounds, CAN, the wires were loaded, no voltage drops, new battery.
After a few days of fighting I left the car, I had enough. I went back to it yesterday and discovered that communication with TCM returned when the battery voltage was below ~11.2V. If I just start the car it loses communication, I connect the power supply it loses communication.
No changes on CAN, the controller gets ~0.4A current. This is the first time I have had this situation, does anyone know what's going on?
Thanks for the advice.
