Repair Instructions

1. EPB System Malfunction

a. Reset the System:

  1. Turn the ignition to the "ON" position without starting the engine.
  2. Press the EPB switch to engage, then hold it for 5 seconds.
  3. Release the switch and press it again to disengage.
  4. Check if the warning light disappears.

b. Replace EPB Switch:

  • If the switch is faulty, remove the center console cover to access it.

3. Sticking or Freezing

a. Check Brake Calipers:

  1. Disassemble the caliper from the rotor using the socket set.
  2. Inspect the caliper piston for corrosion or sticking.
  3. Clean and lubricate the piston with brake grease if necessary.

b. Adjust EPB Calibration:

  • The EPB may need recalibration if it continues to stick. Refer to the service manual for specific calibration procedures.

4. Electrical Failures

a. Check Wiring and Connectors:

  1. Use a multimeter to check the voltage at the EPB switch and motor.
