Roommate owns a 2.2 CL. I replaced the trans last night and dropped it off at his work. While driving the car all guages stopped working. After stopping turning the car off and trying to restart it, nothing happened. All I'm getting is a battery light nothing else, no starter, nothing. All headlights work. The car did ask for the radio code again which tells me its battery related but it has a full charge. Tried a scanner but no codes found. Any ideas??? How would I go about testing the ecm on this car??? Thanks for any help in advance!!!
