|
Electronic Parking Brake apply failed.
|
Electronic Parking Brake faulted during apply && (nonterminal == FALSE)
|
Electronic Parking Brake apply in progress will be stopped due to the fault, caliper may not be fully applied
|
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 backrest motor has unexpectedly stalled, which may cause the motor to recalibrate.
|
The current draw of the backrest motor has exceeded the stall limit.
|
If the stall occurs in an expected region, the backrest motor may recalibrate.
|
No
|
|
|
The battery voltage measurement, nominally 12 volts, was higher than expected.
|
The vbat voltage measurement is higher than 18.5 volts.
|
12V Battery or low voltage systems may be damaged
|
No
|
|
|
The battery voltage measurement, nominally 12 volts, was lower than expected.
|
The vbat voltage measurement, is lower than 6.0 volts. If the measurement is lower than 0.25 volts, we do not set this alert, as this would indicated the switch supply is disabled.
|
12V Battery or low voltage systems may be damaged
|
No
|
|
|
Electronic Parking Brake apply was interrupted. Apply will be retried.
|
(unitFaultStatus == FAULT_STATUS_RETRY) && (csmRequest == apply) && (stateRequest != ESM_DYNAMIC)
|
Electronic Parking Brake did not apply, it will retry an apply and enter fault if retry fails
|
No
|
|
|
HSD for seat heater has shorted
|
HSD for front seat heater trips
|
seat heater isn't functional
|
No
|
|
|
The vehicle controller detects the the low voltage (LV) battery may be overdischarged and no longer functional. This may indicate the LV battery has been damaged due to deep discharge, or it may indicate the LV battery voltage has dropped below the minimum limit for maintaining functionality.
|
The vehicle controller detects LV battery voltage or LV battery Amp hour (Ah) budget are below their limits for 5 seconds.
|
The LV battery may be unable to hold adequate electrical charge to remain functional. Replacement may be necessary, with a separate alert present to indicate that condition if applicable.
|
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
|
|
|
Electronic Parking Brake was not able to determine caliper state on boot.
|
Caliper state saved is unknown, corrupted, or mismatches Electronic Parking Brake Monitor
|
Problem with initializing Electronic Parking Brake
|
No
|
|
|
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.
|
No
|
|
|
The seat track motor has unexpectedly stalled.
|
Current draw exceeds stall limit.
|
Motor will recalibrate if the stall is in an expected region, do nothing otherwise.
|
No
|
|
|
The bladder B has exceeded pressure limits
|
Bladder pressure exceeds 1300hPa (absolute)
|
Damage to bladder or valve block
|
No
|
|
|
The door latch had to be rehomed because of an unexpected movement in the latch's release motor.
|
The latch is not performing a release but the home switch on the release actuator is deactivated.
|
Until this alert clears, the door latch may spontaneously release.
|
No
|
|
|
The door latch had to be rehomed because of an unexpected movement in the latch's release motor.
|
The latch is not performing a release but the home switch on the release actuator is deactivated.
|
Until this alert clears, the door latch may spontaneously release.
|
No
|
|
|
The tilt motor is uncalibrated
|
Motor calibrated is 0
|
Position recall unavailable
|
No
|
|
|
The vehicle controller detects the low voltage (LV) battery voltage is lower than expected during a precharge event. When this occurs too many times, separate alerts will also be present to indicate precharging the high voltage (HV) bus may not succeed and the LV battery may need replacement.
|
An instant resistance check of the LV battery connections to the vehicle controller does not succeed (does not return a healthy result). Alert log signal data should provide more information on specifics, including load current, LV battery temperature, and any detected voltage dip.
|
The LV battery may be unable to support vehicle electrical systems, including precharging the high voltage (HV) bus.
|
No
|
|
|
The bladder A has exceeded pressure limits
|
Bladder pressure exceeds 1300hPa (absolute)
|
Damage to bladder or valve block
|

|
No
|
|
|
The vehicle controller detects that the left headlight has not been aimed or requires re-aiming.
|
A replacement left vehicle controller (VCLEFT) has been installed.
|
The headlights may not properly illuminate the area in front of the vehicle or may dazzle oncoming drivers.
