| Signal Name | Description | Condition | Impact |
|---|---|---|---|
|
The bladder A has exceeded pressure limits
|
Bladder pressure exceeds 1300hPa (absolute)
|
Damage to bladder or valve block
|
|
|
Electronic Parking Brake has been in its current state for too long a time.
|
Electronic Parking Brake has been in its current state for too long a time.
|
EPB may not operate, check for related Electronic Parking Brake alerts.
|
|
|
The low voltage (LV) bus and LV battery are not adequately supported by the power conversion system (PCS).
|
There is 0.5V or greater difference between the PCS voltage and the LV battery voltage.
|
The low voltage electrical system cannot continue to power all vehicle features when the LV bus is not adequately supported. It may be necessary to shed some vehicle electrical loads by cutting power to less essential electronic control units (ECUs), and another alert will be present to indicate that condition. Vehicle may be unable to drive or continue driving, with another alert present to indicate that condition.
|
|
|
Electronic Parking Brake was unable to release fully.
|
Electronic Parking Brake faulted during release && (nonterminal == TRUE)
|
Electronic Parking Brake may not be released, and caliper may be obstructed
|
|
|
The radiator fan brushless motor controller reports a condition affecting its operation.
|
The radiator fan motor controller reports a condition affecting the radiator fan operation.
|
The radiator fan will not be able to run.
|
|
|
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
|
|
|
Front door latch release cam cannot find home position
|
Door latch actuator was resetting the release cam to its home position and timed out
|
Door may not be able to close
|
|
|

|
Latch state transitioned from opening to closed
|

|
|
|
Electronic Parking Brake apply failed.
|
Electronic Parking Brake faulted during apply && (nonterminal == TRUE) && (stateRequest != ESM_DYNAMIC)
|
Electronic Parking Brake may not be applied, and caliper may be obstructed
|
|
|
The intelligent battery sensor (IBS) is reporting a temperature value over 80 degrees C.
|
The measured IBS temperature is greater than 80 degrees C.
|
The IBS may be unavailable, or may not function as expected. Operating at high temperatures will contribute to accelerated low voltage (LV) battery degradation. If the measured temperature is inaccurate due to IBS issues, the LV battery's temperature-compensated voltage target may be lower than expected, also contributing to accelerated degradation.

|
|
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
