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.

When the body control module (BCM) receives a left turn signal ON command from the turn signal switch, the BCM will apply voltage to the left turn signal indicator supply voltage circuit. The turn signal flasher, which is integrated within the BCM, will flash the left turn signal indicator lamp in the instrument panel cluster (IPC) simultaneously with the turn signal lamps.
