Wheel Speed Sensor: General Fault.
|
Three or more sensor signals seem to be affected by temporary failure suspicion at the same time (one or several of the above described failure monitoring are triggered by not plausible or missing WSS signals).
|
Will disable VDC/TC and degrade ABS. Leads to deactivation of BSC and EBD.
|
|
|
Wheel Speed Sensor: General Fault.
|
If the difference between maximum and minimum wheel speed related to a reference speed exceeds 5%. A generic wheel speed sensor fault is set if no wheel specific fault could be determined. During system mode ABS and backup-EBD (Electr. Brake Force Distribution) and below 20 kilometers per hour the deviation is 6 kilometers per hour for velocities < 100 kilometers per hour and 6% for a velocity > 100 kilometers per hour.
|
Will disable VDC/TC and degrade ABS
|
|
|
Wheel Speed Sensor: General Fault.
|
This error will be set if 2 rotation directions of the sensor signal are in one direction, the other 2 rotations are in the other direction OR 2 rotation directions of the sensor signal have no rotation, 1 rotation in one direction, 1 rotation in other direction
|
Will disable VDC/TC and degrade ABS
|
|
|
Wheel Speed Sensor: General Fault.
|
More than one suspected wheel speed sensor failures occur at the same time for more than 500ms. A suspected wheel speed sensor failure is set in the following situation: Noise monitoring- slip monitoring- dynamic monitoring- monitoring of absent signal or monitoring of flat tire sets a suspicious flag.
|
Will disable VDC/TC and degrade ABS
|
|
|
Reverse current at wheel speed sensor supply detected and the reverse protection switch is switched off.
|
Backward power supply of ECU via WSS supply line is detected. One of the WSS power supply lines is shorted to Ubat.
|
Will disable VDC/TC and degrade ABS
