Help!!! For some reason, the battery got drained. After jump starting the ML, the MCS is no longer working. No power but the fuses are fine. What could be wrong? Thanks in advance!

Update: the dealer said that the MCS has a fuse behind the unit. But according to them only the dealer can replace that fuse. Can I do this myself? What tools would I need to take the unit off the dash? What fuse do I need? Thanks again in advance!

Thanks, fkong777! Where is the best place to get the MCS pull out keys? Are they readily available from the dealership? Thanks again!

Also, do I have to do this everytime I jumpstart it? Is this something that need to be added to the things to watch out for on a 163?

a car that can't do the throttle reset.
Yes, dealer sells it.. as does ebay. And I hardly think its a big concern as you won't be jumping the ML that often.
