Actions Taken When the DTC Sets

WARNING: This page is about a different car, the 2008 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.

When DTC B1461 or DTC B1462 sets, the headlamp control module will attempt to return the lamps to a nominal position and disable all requests to both headlamp actuators.
The driver information center (DIC) will display AFL Lamps Need Service.
On vehicles equipped with both AFL and headlamp leveling, the headlamp leveling system will be disabled.
