Circuit/System Description

WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The battery energy control module (BECM) monitors while deviation of the voltage across the battery pack is checked using the 3 module voltage sensors. If one module within the battery pack is bad, it will manifest itself in a high Delta V SOH (state of health).
