Signal Name Description Condition Impact
CAN undervoltage detected.
CAN network voltage below specification
VDC/TC disabled, EBR functionality disabled
Stability Control Active Too Long.
Continuous and strong VDC intervention at front axle for >= 10s
VDC/TC disabled
ABS controler has detected, that there has been no pressure increase for an implausible long time.

Brake Pedal Switch Plausibility monitor against master cylinder pressure sensor failed.
Master cylinder pressure rise is not correlated with switch state
Degrades automatic braking functionality
Brake Pedal Switch Plausibility monitor against master cylinder pressure sensor failed.
Master cylinder pressure rise is not correlated with switch state
Degrades automatic braking functionality
Brake Pedal Switch A: Signal stuck high.
HW failure, connection failure, or improper installation of BLS switch
