System functions: Notes

The steering column switch cluster (SZL) comprises the following functions:

• Monitoring of steering angle and steering-wheel turns
• Monitoring of signals from coil spring cassette
• Reading of signals from wiper/washer switch and cruise-control system steering column stalk and output of signals on the F-CAN
• Reading of signals from turn-signal/main-beam switch and resistance-encoded output of signals to the FRM
• Reading of signals from the BC switch for on-board computer function and from the rocker switch (on turn signal/main-beam switch) and resistance-encoded output of signals to the instrument cluster
• Self-diagnosis (fault memory in DSC)
