Circuit/System Description

WARNING: This page is about a different car, the 2008 Isuzu i-370, 2008 Isuzu i-290, 2008 GMC Canyon, and 2008 Chevrolet Colorado. However, it is still accessible from the selected car via links, so may be relevant.

The generator battery control module (GBCM) monitors its internal battery current sensor for many charging system operations, and also for diagnostic purposes. If reversed polarity of the battery current is sensed, then DTC B151B will set.
