|
The switch may not function or may not function as expected.
|
|
|
A large voltage drop is detected in the input power to the vehicle controller, indicating the resistance on the input power feed to the vehicle controller is higher than expected.
|
Estimated resistance on the input power feed to the vehicle controller is higher than expected.
|
The vehicle controller may be unavailable due to lack of adequate input power, limiting vehicle functionality or making the vehicle inoperable, with at least one other alert specific to that condition present.
|
|
|
One or more of the expected messages the electronic control unit (ECU) receives periodically from the high voltage processor (HVP) ECU is not received, indicating the HVP may be unavailable (MIA).
|
One or more of the expected messages from the HVP ECU is not received.
|
Vehicle may be unable to drive. Charging may be limited or unavailable.

|
Motor current was lower than expected
|
Motor current measurement, with calibration offset subtracted, was lower than 0.25 amps
|
Caliper could be disconnected or the harness is damaged.
|
|
|
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
|
|
|
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
|
|
|
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
|
|
|
More than half of the ECUs on a either the VEH or PARTY bus are missing more than half their messages while the bus should be active
|
If 50% or more of the ECUs the local ECUs listens to are MIA, and the local ECU receives from more than 3 ECUs on this bus. An ECU is MIA if more than 50% of its messages are MIA and that ECU is considered CAN active (see specific ECU's MIA alert for CAN active conditions).
|
Vehicle functionality may be degraded.
