Common Problems with the Electronic Parking Brake in the Toyota Highlander (Fourth Generation, 2020-Present)

The electronic parking brake (EPB) in the Toyota Highlander can present several issues that may affect its performance. Below is a detailed overview of common symptoms, diagnostic steps, tools required, and repair instructions for addressing these problems.

Common Symptoms
  1. Warning Lights: The EPB warning light may illuminate on the dashboard.
  2. Inability to Engage/Disengage: The electronic parking brake may fail to engage or disengage.
  3. Unusual Noises: Grinding or clicking noises may be heard when the EPB is activated.
  4. Vehicle Rolling: The vehicle may roll when parked despite the EPB being engaged.
  5. Error Messages: The vehicle's multi-information display may show error messages related to the parking brake.
Step 1: Initial Inspection
  • Visual Check: Inspect the EPB switch and wiring for signs of damage or corrosion.
  • Listen for Noises: With the vehicle in the "On" position, listen for any abnormal sounds from the rear brake assembly.
Step 2: Check for Error Codes
  • OBD-II Scanner: Connect an OBD-II scanner to the vehicle's diagnostic port.
  • Retrieve Codes: Check for any stored trouble codes related to the EPB system. Codes may include:
    • C1391: EPB malfunction
    • C1410: EPB actuator failure
Step 3: Functionality Test
  • Engage and Disengage: Attempt to engage and disengage the EPB with the switch while the vehicle is in "Park."
  • Observe Responses: Note if the system responds appropriately or if there are any delays or failures.
Step 4: Inspect Components
  • Brake Pads & Calipers: Inspect the rear brake pads and calipers for wear or damage.
  • EPB Actuator: Check the EPB actuator for proper operation and alignment.
Step 5: Check Power and Ground
  • Multimeter: Use a multimeter to check for power and ground at the EPB switch and actuator.
  • Wiring Harness: Inspect the wiring harness for continuity and any breaks or shorts.
Tools Required
  • OBD-II Scanner
  • Multimeter
  • Basic Hand Tools (screwdrivers, pliers, wrenches)
  • Torque Wrench
  • Brake Cleaner
  • Jack and Jack Stands
  • Safety Glasses and Gloves
Repair Instructions
Repair Scenario 1: EPB Actuator Replacement

Symptoms: Warning light is on, EPB fails to engage/disengage, and error codes indicate actuator failure.

Step 1: Prepare Vehicle

  1. Safety First: Ensure the vehicle is on a level surface. Engage the regular parking brake.
  2. Disconnect Battery: Remove the negative terminal from the battery to prevent electrical shock.

Step 2: Access the EPB Actuator

  1. Lift the Vehicle: Use a jack and jack stands to safely lift the rear of the vehicle.
  2. Remove Rear Wheels: Take off the rear wheels to access the brake assembly.

Step 3: Remove Old Actuator

  1. Locate the EPB Actuator: The actuator is typically mounted on the brake caliper.
  2. Disconnect Wiring: Carefully disconnect the wiring harness from the actuator.
  3. Unbolt Actuator: Remove bolts securing the actuator to the caliper.
  4. Remove Actuator: Take out the old actuator.

Step 4: Install New Actuator

  1. Position New Actuator: Place the new actuator in position.
  2. Bolt Down: Secure the actuator with bolts and torque to manufacturer specifications.
  3. Reconnect Wiring: Reattach the wiring harness.

Step 5: Reassemble Components

  1. Replace Brake Pads: If worn, replace the brake pads as well.
  2. Reinstall Wheels: Put the rear wheels back on and lower the vehicle.
  3. Reconnect Battery: Reattach the negative terminal to the battery.

Step 6: Final Checks

  1. Calibrate EPB: Follow the vehicle's service manual to calibrate the new actuator using a diagnostic tool if necessary.
  2. Test EPB Function: Engage and disengage the EPB to ensure proper operation.
Repair Scenario 2: Wiring Issues

Symptoms: Warning light on, intermittent EPB function.

Step 1: Inspect Wiring

  1. Visual Inspection: Look for frayed or damaged wires in the EPB circuit.
  2. Use Multimeter: Test continuity of wires from the EPB switch to the actuator.

Step 2: Repair or Replace Wiring

  1. Splice or Replace: If damage is found, splice and solder wires or replace the harness as needed.
  2. Protect Connections: Use heat-shrink tubing or electrical tape to protect connections.
Conclusion

By following these diagnostic and repair steps, you can effectively address common electronic parking brake issues in the Toyota Highlander. Always refer to the vehicle’s service manual for specific instructions and torque specifications for your particular model year. If problems persist, professional assistance may be required.
