Error codes after removing ecu
Hi all, I had sent my ecu out to be unlocked for a tune and upon reinstall an getting the following codes u0100 and u0073. Tuner had said to check all connections and everything looks in place solidly. Anyone know which connector the codes could be referencing? Feeling kind of like I've messed up.
