Module, Adaptive Front Lighting System (AFLS): Description
Vehicles equipped with the optional Adaptive Front Lighting System (AFLS). The AFLS module is located on a bracket behind the passenger side knee air bag, to the right of the HVAC unit.
This module works in conjunction with the front and rear axle (leveling) sensors, the headlight swiveling motors and electronic message inputs received over the Controller Area Network (CAN) data bus from other electronic modules in the vehicle. The module provides automatic headlight beam aim adjustment to compensate for changes in vehicle direction caused by changes in vehicle loading, acceleration, deceleration, steering wheel angle and YAW rate.
Concealed within the module housing is the circuitry of the module itself, which includes a microcontroller. The module is connected to the vehicle electrical system through an integral connector receptacle by a take out and connector of the headlight and dash wire harness.
The AFLS module cannot be adjusted or repaired and, if ineffective or damaged, it must be replaced. The AFLS module is Flash programmable.
