EPB ECU raise DTC if EPB actuator apply/release state is not known or both side apply/release state is not same. Usually power, actuator, motor DTC will cause this DTC to be raised.
DTC Detecting Condition
Item | Detecting Condition | Possible Cause |
DTC Strategy | Monitoring EPB actuator state
| EPB actuator state is unknown EPB state of both side are not the same Due to other DTC above case happen If only one side is actuator by GDS |
Enable conditions | IG ON Battery voltage between 9V and 16V
|
Threshold value | EPB actuator state is not known Both side actuator state are not the same
