ok i've had two mechanics look at the car for my battery draining issue and all the can say is it iss either a shorted wire on my egi fuse or a bad ecu. i did a code check on the ecu and got multiple codes. 21: ignition siganl primary. this is the one the concerns me. does this mean the ignition portion of the ecu is bad? any help is appreciated.
