| Signal Name | Description | Condition | Impact |
|---|---|---|---|
|
WSS_FL HET TU buffer noise (enormous amount of edges ocurred).
|
Signal from WSS is noisy/implausible
|
Will disable VDC/TC and degrade ABS
|
|
|
WSS fault due to missing wheel speed signal.
|
Wss fault due to missing wheel speed sensor signal
|
Will disable VDC/TC and degrade ABS
|
|
|
WSS fault due to missing wheel speed signal.
|
No stop pulses occurred on WSS
|
Will disable VDC/TC and degrade ABS
|
|
|
A wheel speed sensor with wrong sensor type is mounted on wheel front left.
|
A wheel speed sensor with wrong sensor type is mounted on wheel FR.
|
Will disable VDC/TC and degrade ABS
|
|
|
Left Front Wheel Speed Sensor against second signal failed due WSS signal interferences or disturbances.
|
WSS signal interferences or disturbances
|
Will disable VDC/TC and degrade ABS
|
|
|
Left Front Wheel Speed Sensor: Plausibility against second signal failed due to monitoring of wheel speed differences.
|
Large wheel speed diff relative to other sensors detected
|
Will disable VDC/TC and degrade ABS
|
|
|
Plausibility fault while monitoring of wheel direction.
|
At least one wheelspeed sensor is mounted in the wrong direction. This error will be set if case one: 1 rotation direction of the sensor signal is in one direction and the other 3 rotations are in the other direction OR case two: 1 rotation direction of the sensor signal has no rotation and 1 rotation in one direction and 2 rotations in other direction.
|
Will disable VDC/TC and degrade ABS
|
|
|
Wss fault due to Alignment or adjustment incorrect.
|
Bad airgap, wheel vibrations or incorrectly mounted WSS.
|
Will disable VDC/TC and degrade ABS
|
|
|
Left Front Wheel Speed Sensor Generic Fault.
|
WSS test failure of WSS_FL (Short circuit supply line to UBATT short circuits between sensors any line failure)
|
Will disable VDC/TC and degrade ABS
|
|
|
Short circuit of the WSS_FR sensor line to GND or line interruption (sensor or supply line).
|
Short circuit of the sensor line to GND or line interruption (sensor- or supply line) .
|
Will disable VDC/TC and degrade ABS
|
|
|
Short circuit of the WSS_FR sensor line to 12V.
|
Short circuit of the wheel speed sensor line to + voltage.
|
Will disable VDC/TC and degrade ABS
|
|
|
The Electronic Stability Program (ESP) detects that the iBooster (IBST) electronic control unit (ECU) will not execute any External Brake Requests (EBRs) as they are reported as unavailable.
|
The IBST ECU reports that EBRs are unavailable.
|
EBRs will not be executed.
|
|
|
The Electronic Stability Program (ESP) electronic control unit (ECU) is not receiving messages from the iBooster (IBST) ECU on the Party controller area network (CAN) bus within the expected time frame.
|
The ESP ECU does not receive messages from the IBST ECU on the Party CAN bus within the expected time frame.
|
Brake boost functionality may be limited or unavailable.
|
|
|
The Electronic Stability Program (ESP) detects that the vehicle is skidding while the wheels are locked.
|
The ESP detects the vehicle is skidding with locked wheels.
|
No expected impact on vehicle functionality. The vehicle should be driven with caution due to the road conditions.
|
|
|
External Brake Request (EBR) is active. This feature manages the brake commands for Autopilot and vehicle comfort features, such as vehicle hold.
|
EBR is active.
|
No expected impact on vehicle functionality.
|
|
|
Brake Disk Wipe (BDW) is active. This feature will help keep the brakes dry during cold and/or wet conditions.
|
BDW is active.
|
No expected impact on vehicle functionality.
|
|
|
Regenerative Traction Control is active. The Electronic Stability Program (ESP) may try to prevent wheel slips under regenerative braking.
|
Regenerative Traction Control is active.
|
No expected impact on vehicle functionality. The vehicle should be driven with caution due to the road conditions.
|
|
|
Roll Over Mitigation (RMI) is active. The Electronic Stability Program (ESP) may activate the brakes to help stabilize the vehicle.
|
RMI is active.
|
The ESP may attempt to prevent the vehicle from rolling over by engaging the brakes.
|
|
|
The Electronic Stability Program (ESP) detects that the brake pressure is too low for the given brake pedal stroke, causing the Hydraulic Brake Boost (HBB) to be activated.
|
The HBB is activated because the brake pressure is too low for a given brake pedal stroke.
|
Braking performance may be reduced. The ESP pump may be activated to increase the brake pressure.
|
|
|
The Electronic Stability Program (ESP) detects that the one or more of the brakes are faded, causing Hydraulic Fade Compensation (HFC) to be activated.
|
HFC is activated because all of the following conditions have been met: (1) the master cylinder pressure exceeds a certain pressure; (2) the Anti-lock Braking System (ABS) is not active; (3) the vehicle does not decelerate in time.
|
Braking performance may be reduced due to faded brakes. The ESP pump may be activated to increase the brake pressure.
