Here's what we know now:</div>
<div><br></div><div>To wake up the VCM (Main controller), the TCU sends a msgID of 68C on the EV CAN bus with one byte of 00. On 2013 and newer models wake up solely on the CAN message. </div><div><br></div><div>For 2011 or 2012 models the TCU will bring a logic line high that connects to the VCM briefly as well to wake it up. Page 64 of the "AV" section of the 2012 service manual shows the pinout of the TCU. You will need to splice into Pin 11 (light green? wire) on the large connector going to the TCU and make an appropriate circuit to pull it high briefly when the OVMS module sends the 68C message. When doing non "remote charge" testing you might be able to hit the charge override button (which uses another line to wake the VCM) then send 68C. I think that might work for testing. :-)</div>
<div><br></div><div>Once the VCM is awake it looks to the TCU status message to see what's up. The status message has a msgID of 56E and the first byte determines the status (the 6 other bytes are FF). The 56E message repeats every 100ms whenever the EV CAN bus is active. The various modes are:</div>
