Causes
- Blown fuse or low battery voltage/power supply interruption to EPB
- Damaged wiring or poor connector contact at EPB actuator or module
- Corroded or bent pins in connector(s)
- Faulty EPB actuator or automatic trigger unit
- Loss of CAN/LIN network communication or module not present on bus
- Software/firmware error or module fault after update
Symptoms
- EPB warning lamp illuminated or message in instrument cluster
- Auto-parking brake function unavailable or inoperative
- Vehicle displays ‘electric parking brake fault’ or similar text
- Unable to apply or release parking brake using automatic function
- Driveability may be restricted or vehicle may refuse to shift into gear in some models
- Multiple related communication or convenience module faults present
What to check
- Retrieve all stored DTCs and freeze frame data with a capable diagnostic scan tool
- Check battery voltage (engine off and cranking) and charging system health
- Visually inspect fuses related to EPB and vehicle convenience/traction modules
- Inspect EPB actuator/module connector for corrosion, bent pins, water ingress or loose terminals
- Check harness for chafing, damage, repairs or aftermarket taps near rear axle and module location
- Using a scan tool, confirm the EPB module is present on the network and see if the module responds to diagnostics
Signal parameters
- Battery supply to EPB actuator: nominal ~11–14.5 V (verify with manufacturer spec)
- Ground circuit: continuity to chassis ground, near 0 Ω under static check
- CAN bus idle voltages typically near ~2.5 V on each CAN_H and CAN_L line; differential messages at expected bus rate (check vehicle-specific CAN speed: commonly 250–500 kbps)
- LIN single-wire lines idle near battery through pull‑up (vehicle-specific voltage); expect LIN frame traffic if used
- Actuator coil/motor resistance: compare to manufacturer spec (motor/driver should not be open circuit)
- Fuse continuity: fuse supplying EPB should show continuity or expected voltage on both sides when fused
Diagnostic algorithm
- Read and record U1119 and any other DTCs and freeze frame data. Do not clear codes yet.
- Check battery state and fuses: measure battery voltage, check charging system, inspect EPB-related fuse(s) and relays; repair/replace as needed.
- Visually inspect EPB actuator/module connectors and harness for damage, corrosion or water intrusion; repair any issues and reseat connectors.
- With a scan tool, confirm whether the EPB module appears on the CAN/LIN network and check live data for actuator status. If module not present, continue physical wiring checks.
- Measure power and ground at the EPB actuator connector: verify constant battery feed, switched feed (if applicable), and a good ground. Repair wiring or grounds that are out of spec.
- Check CAN/LIN communication: measure CAN_H and CAN_L voltages and probe for message activity with scope, or use a bus analyzer to confirm traffic. Repair broken bus wiring, terminators or shorts.
- Perform continuity/resistance checks of EPB motor/actuator circuits per manufacturer values. If open or out of range, suspect actuator/motor or internal driver failure.
- If wiring and power/ground are good but module is unresponsive, attempt module wake/reflash according to factory procedures; confirm software version and update if recommended.
- After any repair, clear codes, cycle ignition, use EPB function test via scanner, and perform a road or function test to confirm repair. Monitor for reappearance of U1119.
- If fault persists after wiring and module checks, consider replacement of the EPB actuator/control unit following manufacturer procedures and reprogram if required.
Likely causes
- Loose or corroded connector on the parking brake actuator
- Open or shorted power supply or ground to EPB actuator
- Failed EPB actuator/motor control unit
- CAN bus communication fault between EPB module and vehicle network
- Blown fuse feeding EPB control circuit
Fault status
Status
No signal from electrically controlled parking brake automatic trigger — communication or power supply fault to EPB actuator/module.
Repair difficulty: Medium
Diagnostic time: 0.5-3 hours
