Turn Signal Warning

WARNING: This page is about a different car, the 2007 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.

The body control module (BCM) activates an audible warning as a reminder that the turn signal has been on for a distance of more than 1.20 km (0.75 mi). The BCM receives the vehicle speed and distance via the vehicle speed signal circuit. The turn signal chime will use a tone that is synchronized with the turn signal flasher. The BCM will activate the turn signal chime when the following occurs:

The ignition is ON.
Left or right turn signal switch is ON.
The vehicle has traveled further than 1.20 km (0.75 mi).
