| Signal Name | Description | Condition | Impact |
|---|---|---|---|
|
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.
|
|
|
The Electronic Parking Brake (EPB) reports the driver is leaving and parks the vehicle.

|
|
|
Unexpected voltage seen on non-continuous device outputs. Left mirror fold and tilt, left windows, and steering column motors may be disabled.
|
Voltage is above 8V for 200ms on at least one of the following device outputs while none of them are being driven: left mirror fold and tilt, left windows, and steering column motors
|
Left mirror fold and tilt, left windows, and steering column motor control may be disabled
|
|
|
Electronic Parking Brake Monitor detected Electronic Parking Brake driving the motor the incorrect direction for the given state.
|
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.
