ATC, auto traction control. this is to maintain stability during slippage. you may have a closed sensor circuit that is continuing to drain power when the ignition switch is in the off position. Tcb is a module fuse. I would preform the test below to isolate any other draws that may exist.
Here is the procedure I use to isolate a battery drain. Remove negative battery cable from the battery. Using a 12-volt test light, hook one end to the negative battery post the other end to the negative battery cable you just disconnected. The test light will glow or "light" if there is a drain. If the "light or glow" is faint, that is probably normal draw for the clock or computer. If the "light or glow" is bright, then there is a large drain. That should be corrected. Now start removing and replacing the fuses one by one until the light goes out; that one will be the circuit with the drain. Remember to hold in the button in the door jam for the interior lights.

that is how i found the where the draws were, tcb and atc both are large draws as well as the alt which i am replacing, would either of these other two draws be related to eachother?
