Vehicle attempted a power state transition which the Electronic Parking Brake did not agree with.
VCFRONT and EPB vehicle power states are not the same
A controller may be stuck in the wrong power state. Could block sleep or other functions
Electronic Parking Brake not sure if it is a left or a right.
Electronic Parking Brake could not read genealogy when starting.
Electronic Parking Brake and vehicle power functions will be severely degraded.
Vehicle speed is limited based on ultrasonic distance measurements. Currently in ghosted alert.
Autopilot command speed to DI is too high for reported Object on Course.
Summon will be abruptly aborted.
EPB releases no-load is measured using derivative of current. Currently in ghosted alert.
No-load current suggested the EPB was not in no-load causing release to continue.
EPB may not released far enough causing drag on rotor.
Electronic Parking Brake apply was interrupted during dynamic apply. Apply will be retried.
(unitFaultStatus == FAULT_STATUS_RETRY) && (stateRequest == ESM_DYNAMIC)
Electronic Parking Brake did not apply, it will retry applying and enter fault if retry fails
When EPB was applying the current measured went above the max no load current before piston position estimate predicted it would.
EPB measure current greater than max no load current before piston position estimate expect it would.
EPB may have debris blocking it from clamping correctly.
The Emergency Notification Signal (ENS) harness may be disconnected or the Restraints Control Module (RCM) may be missing (MIA).
Emergency Notification Signal (ENS) period is not within 10% of 0.001 or 0.1 seconds, and duty cycle is not between 60% and 40%.
Loss of redundancy on high voltage disconnection signal.

The Electronic Parking Brake (EPB) enabled Winch Mode but did not receive the expected messages from the steering system.
Winch Mode is enabled, but the EPB did not receive the expected messages from the steering system.
Steering performance may be reduced or steering may be unavailable until Winch Mode is disabled.
Electronic Parking Brake has detected a vehicle speed condition that caused it to exit winch mode.
While in winch mode, Electronic Parking Brake detects a speed class of fast or unknown.
Vehicle exits winch mode and applies parking brakes.
Startionary detect can park vehicle if all speed sources are MIA and algo detects no motion.
Speed sources MIA, brake press held, RCM detects no motion, speed sources unknown.
EPB will park.
Electronic Parking Brake apply was interrupted during dynamic apply. Apply failed.
Electronic Parking Brake faulted while applying and during ESM_DYNAMIC
Electronic Parking Brake could not be applied, car may be free rolling
