General Description
The EPB system is the shorten word of Electric Parking Brake system. This system is the parking brake device which is used instead of the conventional hand-break system. When a driver presses the EPB button, the button signal is delivered to the EPB ECU and then the EPB actuator which consists of a motor and a gears is activated. At this time, while the motor in the EPB actuator rotates, the motor pulls the EPB cable connected to the rear wheels. Among components of EPB system, the force sensor is installed inside of the EPB ASS'Y and its role is to senses the tension of the parking cable.
DTC Description
When the force sensor's calibration is not carried out, the EPB ECU shows this DTC and turns on the warning light on the cluster.
DTC Detecting Condition
Item | Detecting Condition | Possible Cause |
DTC Strategy | Monitoring the state of the force sensor's calibration
| Force sensor's calibration not carried out Faulty EPB ECU(inside EPB ASS'Y)
|
Threshold value | In a case of not carring out the force sensor's calibration
|
Fail-Safe | According to the calibration, the EPB function is inhibited/ available
