Static Bending Lamps (AFS Led Only)
The LED static bending lamps are designed to illuminate the direction of travel when cornering at low speeds. The static bending lamp functionality, which is controlled by the BCM/GWM, operates using inputs from the steering angle sensor and vehicle speed information from the ABS control module.
The static bending lamp is incorporated into the headlamp assembly. The design of the lens projects a spread of light from the vehicle at approximately 45 degrees to the vehicle axis. The static bending lamp uses LEDs located in the headlamp housing.
The static bending lamps operate with a steering angle sensor CAN bus signal which is received by the BCM/GWM. The BCM/GWM monitors this signal and vehicle speed and activates the static bending lamp LED. When the operation parameters of the lamp are reached, the BCM/GWM snaps the static bending lamp LED on.
When the lamp is switched off, the BCM/GWM fades the LED off by decreasing the Pulse Width Modulation (PWM) voltage in a linear manner over a period of 1 second. The static bending lamps can only be active for a maximum of 3 minutes at any given time.
