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

The Electronic Parking Brake (EPB) attempted to transition to DYNAMIC before the Electronic Parking Brake Monitor (EPBM) measured the minimum current required to allow the transition.

The brake caliper may not have the expected braking force.

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

Electronic Parking Brake attempted to remain in PARKING while Electronic Parking Brake Monitor had measured more than the maximum current allowed to remain in PARKING.

Caliper lifetime may be degraded.

48V bus is reported undervoltage on VCLEFT while the vehicle is in Drive.

LV bridge is open. Impacted load(s) unavailable in Drive.

DI requests unpark and PM doesn't allow it within 40ms or is MIA

Fault or error occurred on the DI

The load voltage does not meet the power source voltage in the expected amount of time.

The load being precharged may not turn on. Vehicle functions relying on the load being precharged may not operate as expected.

Electronic Parking Brake attempted to remain in DYNAMIC_APPLYING while Electronic Parking Brake Monitor had measured more than the maximum current allowed to remain in DYNAMIC_APPLYING.

The caliper may have a higher than expected braking force.

Electronic Parking Brake attempted to transition to PARK while Electronic Parking Brake Monitor had yet to measure the minumum current required to allow the transition.

The caliper may not have the expected holding force.

48V bus is reported overvoltage on VCLEFT while the vehicle is in Drive.

LV bridge is open.

Exiting SLEEP_STANDBY vehicle state without successfully putting Controller Area Network (CAN) buses to sleep.

The vehicle state of charge (SOC) may decrease faster than expected because the vehicle is not going to sleep.

Driver is detected to be leaving while in Offroad Mode

Vehicle will not exit drive due to driver leaving

Electronic Parking Brake Monitor detected Electronic Parking Brake driving the motor the incorrect direction for the given state from the voltage measured across the motor.

EPB operation may be reversed.

No current flow detected to / from the low voltage (LV) battery for an extended time period.

Loss of support from the low voltage (LV) battery, so the vehicle electrical system is only supported via the power conversion system (PCS). Lead acid only: Some vehicle features may be unavailable due to load shedding. There should be another alert present to indicate this.

Bladder pressure exceeds 1300hPa (absolute)

Damage to bladder or valve block

CAN bus termination not set when expected

Vehicle CAN bus may have errors

The EPB attempted to park due to the driver being detected as leaving.

The EPB will be applied.

CAN bus termination set when unexpected

Vehicle CAN bus may have errors

Radiator Fan Controller not responding on LIN

Radiator Fan Controls will not function

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.
