| Signal Name | Description | Condition | Impact | Important |
|---|---|---|---|---|
|
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.
|
No
|
|
|
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.
|
No
|
|
|
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.
|
No
|
|
|
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.
|
No
|
|
|
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.
|
No
|
|
|
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.
|
No
|
|
|
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.
|
No
|
|
|
The Electronic Stability Program (ESP) determines that an emergency stop may be required, causing the Hydraulic Brake Assist (HBA) to be activated. The ESP may also increase the brake pressure by running the ESP pump.
|
The HBA is activated as the operating speed of the brake pedal exceeds the maximum threshold.
|
The ESP may increase the brake pressure.
|
No
|
|
|
Trailer Sway Mitigation (TSM) is activated as the Electronic Stability Program (ESP) detects the vehicle and trailer may be swaying. The ESP may activate the brakes to help stabilize the vehicle and trailer.
|
TSM is active.
|
The ESP may activate the brakes to help prevent the vehicle and trailer from swaying.
|
No
|
|
|
The Electronic Brake Force Distribution (EBD) is active due to early onset of brake related wheel slip(s) at one or more wheels.
|
The EBD is active.
|
No expected impact on vehicle functionality. The vehicle should be driven with caution due to the road conditions.
|
No
|
|
|
The Tesla Vehicle Dynamics Controller (TVDC) is active due to lateral stability related wheel slip(s) at one or more wheels.
|
The TVDC is active.
|
No expected impact on vehicle functionality. The vehicle should be driven with caution due to the road conditions.
|
No
|
|
|
Brake Torque Control (BTC) is active due to traction related wheels slip(s) at one or more wheels.
|
BTC is active.
|
No expected impact on vehicle functionality. The vehicle should be driven with caution due to the road conditions.
|
No
|
|
|
The Electronic Stability Program (ESP) is active due to lateral stability related wheel slip(s) at one or more wheels.
|
The ESP is active.
|
No expected impact on vehicle functionality. The vehicle should be driven with caution due to the road conditions.
|
No
|
|
|
The Anti-lock Braking System (ABS) is active due to brake related wheel slip(s) at one or more wheels.
|
The ABS is active.
|
No expected impact on vehicle functionality. The vehicle should be driven with caution due to the road conditions.
|
No
|
|
|
CAN undervoltage detected.
|
CAN network voltage below specification
|
VDC/TC disabled, EBR functionality disabled
|
No
|
|
|
Stability Control Active Too Long.
|
Continuous and strong VDC intervention at front axle for >= 10s
|
VDC/TC disabled
|
No
|
|
|
ABS controler has detected, that there has been no pressure increase for an implausible long time.
|
ABS controller detects that there have been no pressure increases and wheel has not recovered. Returns brake pressure control to driver
|
VDC/TC disabled, possible wheel lock
|
No
|
|
|
ABS Active Too Long.
|
Continuous and strong ABS intervention at front axle for >= 10s
|
VDC/TC disabled
|
No
|
|
|
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
|
No
|
|
