The last two posts is the best videos I could find. The first one is for your large battery in the trunk spare tire area. (www.youtube.com/watch?v=Jak7xKCYOq0). The second one is for you smaller one for the SBC. I believe this is the one giving you the issues. (http://m.youtube.com/watch?v=neVPZnHAF_w&feature=relmfu ). Hope this helps

Battery in engine bay is only for starting. All other electrical functions of the car are handled by the auxiliary battery in the trunk.

Thought this was a big deal. Got "Auxiliary Battery Malfunction" on my dash yesterday. Today, in addition, there was a message that read "Change Key Battery." Brought the car into dealer & service advisor said bring the key to the cashier. In less than one minute, the cashier changed the battery at no charge & gave me back the key. When I started the car both messages disappeared & I was on my way. Very simple solution.
