WARNING: This page is about a different car, the 2008 Pontiac G5 and 2008 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.

Ignition ON, with a scan tool perform the Display Test for the instrument panel cluster (IPC) and observe the high beam indicator.

If the high beam indicator illuminates during the test, replace the BCM.
If the high beam indicator does not illuminate during the test or remains illuminated at all times, replace the IPC.
