MCM reset

MCM reset

After the reset, the IMA battery SOC indicator may show no charge. This is normal, and will correct it self once the car is driven several miles.
A more aggressive (and wasteful)technique is the forced charge.
The Forced charge procedure is to pull the #15 EPS fuse (40A) from the under hood fuse/relay box, then start the engine in neutral and hold the rpm at ~3500 rpm till the battery gauge becomes normal.

So far the simplest techniques is to just drive normally for 5-10 minutes, and the batteries should charge right up.
