Electronic Parking Brake (EPB) Calibration
What it does
- Calibrates the electronic parking brake system
- Ensures correct clamping force and actuator operation
- Synchronizes EPB status with the instrument cluster
When it is required
- After EPB actuator or module replacement
- After brake pad or caliper replacement
- After battery disconnection or replacement
- When EPB warning lights or faults appear
Conditions that must be met
- Vehicle stationary on level ground
- Wheels properly secured
- Ignition ON, engine OFF
- Stable battery voltage
- No active EPB fault codes
What happens during calibration
- EPB actuators move through full range
- Clamping force and mechanical limits are learned
- System stores baseline values for:
- Brake engagement
- Release detection
- Warning thresholds
If calibration is not performed
- EPB may not hold vehicle properly
- Pedal or lever feedback may be incorrect
- Warning lights may remain active
- Reduced parking safety
After calibration
- Verify EPB status and indicator lights
- Test parking brake engagement and release
- Confirm no EPB warnings or faults remain
