Please bear with me. New to this, so trying to play catch up and I apologize in advance.
Can you help me locate the ground connections? I clear the codes and they come back almost as soon as I start the car so I'm going to lie and say current and not history. Been using battery charger to keep up with keeping battery charged as this car has always been known to run down a battery in a couple weeks if it's not driven regularly; but with the extra attention with charger seems to do fine.
EBTCM fuses are which ones and where are they located?

Another thing to try if getting bad ground codes is to unplug and plug the two EBCM connectors. I was getting a persistant bad ground code, even after cleaning all the ground connections. I then unplugged and plugged a few times and the code (1242?) never came back again.
