Function

High beam
The combination switch is set to the high beam switch position. The steering column module records the switch position of the combination switch and sends a high beam "ON" signal over CAN-B to the central gateway control unit.

The central gateway control unit sends a high beam "ON" signal over CAN-B to the front SAM control unit.

The front SAM control unit sends the high beam "ON" message over CAN-B to the instrument cluster and actuates the left high beam in the left front lamp unit (E1) and the right high beam in the right front lamp unit (E2).

The instrument cluster actuates the blue high beam indicator lamp (A1e3).

Headlamp flasher
When the headlamp flasher is pressed the functional sequence and signal flow is the same as for the high beam actuation.

The difference between headlamp flasher and high beam is the switch position of the combination switch. This must be moved to the headlamp flasher switch position and held there.

The headlamp flasher remains active as long as the combination switch is held in the headlamp flasher switch position.

The headlamp flasher functionality is independent of the rotary light switch position.
