System Description: Notes

AFS control unit controls AFS and headlamp auto aiming.

The following signals are input to AFS control unit via CAN communication:

• Steering angle sensor signal
• A/T position indicator signal
• Low beam status signal
• Vehicle speed signal
• Engine speed signal

Other signals are input as follows:

• AFS switch signal from AFS switch connected to AFS control unit
• Height sensor signal from height sensor connected to AFS control unit
• Swivel position sensor signal from swivel position sensor built into both right and left swivel actuators connected to AFS control unit

In response to the state of control, AFS control unit switches commands of AFS off indicator signal sent to unified meter and A/C amp. via CAN communication; and then turns on/off or blinks AFS off indicator lamp built in the combination meter.
