Signal Name Description Condition Impact Important
Brake temperature is above 200C and slope is greater than 10%
The max of the rear brake calipers is hotter than 200 C and slope is greater than 10%
Car may not be secured by Electronic Parking Brake on current road grade, may be free rolling
No
Brake temperature is above 200C and slope is greater than 5%
One Electronic Parking Brake faulted and the max of the rear brake calipers is hotter than 200 C and slope is greater than 5%
Car may not be secured by Electronic Parking Brake on current road grade, may be free rolling
No
EPB calculate brake hw config and epb hw config independently and checks they are the same
All GTW config valid for EPB. Brake hw type and epb hw type do not resolve to same EPB config
EPB may be misconfigured for vehicle setup. Could result in caliper drag and insufficent clamp force
No
Road grade is too steep to secure vehicle and trailer with Park Brake
Attempt to engage parking brake when vehicle with trailer is stopped on too steep a road grade for Electronic Parking Brake to secure the vehicle and trailer effectively
Car may not be secured by Electronic Parking Brake on the current road grade, may be free rolling
No
Electronic Parking Brake release failed due to idle fault
Electronic Parking Brake is idle faulted & release requested
Caliper is disconnected and fails to release
No
Electronic Parking Brake noticed very noisy current
At <-10C noisy motor current for more than 1s during inrush or anytime during no-load
Diagnostic alert for noisy current while Electronic Parking Brake is active
No
The electrical current flowing through the left vehicle controller (VCLEFT) eFuse is greater or equal to 100A. The VCLEFT eFuse circuit may open (trip) if the low voltage (LV) electrical system loads are not reduced. The vehicle controller requests the VCLEFT to shed vehicle electrical loads by cutting power to the less essential loads.
The VCLEFT eFuse current value equals or exceeds 100A for 100 milliseconds.
Some convenience features controlled by the VCLEFT will be unavailable as the vehicle controller limits the LV electrical system current draw by cutting power to some loads.
No
Electronic Parking Brake is preparing to enter winch mode
Winch mode request has been made.
Winch mode may not be entered successfully unless customer keeps foot on brake
No
The compressor power index is lower than expected, which typically indicates a condition affecting the compressor. This can also indicate a condition affecting the discharge or suction pressure sensors. The compressor power index measures the ratio of estimated nominal compressor power consumption against electrical power the compressor actually consumes. A low index value indicates the compressor is drawing / consuming significantly more power than a nominal compressor would be expected to consume.
The compressor power index, which compares expected compressor power consumption against actual consumption, drops below expected levels.
Thermal system may show reduced effectiveness. Cabin climate control performance may be limited, with cabin heating / cooling not performing at expected levels.
No
If vehicle reaches 8.8kph, EPB will park
Vehicle speed of 8.8kph in free roll Mode
EPB is applied.
No
DI requested unpark but PM didn't allow it
DI requests unpark and PM doesn't allow it within 40ms or is MIA
Fault or error occurred on the DI
No
Stability Control has begun Controlled Deceleration for Parking Brake
ESM_state == ESM_DYNAMIC_EXTERNAL
Stability Control is actuating, Electronic Parking Brake may be idle faulted
No
EPB's brake HW config is not compatible remote EPB's brake HW config
Remote EPB is present and local EPB has learnt brake HW config but is not compatible with remote brake HW config
Remote and local EPB brake HW config is incompatible, parking brake function may be degraded
No
Electronic Parking Brake is performing dynamic apply
ESM_stateRequest == ESM_DYNAMIC
Unable to perform Controlled Deceleration for Parking Brake due to Stability Control failing or unavailable
No
Electronic Parking Brake was attempting to dynamic park, Controlled Deceleration for Parking Brake is unavailable, and speed crossed above 8.8kph
EPB_unitStatus == EPB_STATUS_DYNAMIC_PARKING, and speed crosses above 8.8kph or acceleration is above 5mph/s
Car interrupted parking due to travelling at speed, Electronic Parking Brake not applied
No
Stability Control has begun Controlled Deceleration for Parking Brake
ESM_state == ESM_DYNAMIC_EXTERNAL
Stability Control is actuating, Electronic Parking Brake may be idle faulted
No
will prevent EPB from parking when the driver leaves
EPB enters Free Roll Mode from UI request
Car will be free rolling
No
Electronic Parking Brake's learned configuration does not match the reported config from the gateway
Electronic Parking Brake HW type does not match HW type reported by gateway and 5 seconds have passed since gateway booted up
Hardware does not match current configuration, parking brake function may be degraded
No
One Electronic Parking Brake (EPB) not applied, and road grade is too steep to secure vehicle with only one EPB
Only one Electronic Parking Brake (EPB) applied and grade too steep for one EPB to hold the vehicle
Car may not be secured by Electronic Parking Brake on current road grade, may be free rolling
No
Customer facing alert issued when Electronic Parking Brake is applied at higher than 5mph
Entry to states ESM_DYNAMIC, ESM_DYNAMIC_EXTERNAL, ESM_DYNAMIC_PENDING
User facing notification that informs Electronic Parking Brake is dynamically applying
No
