Parking Brake Actuator: Service and Repair

ELECTRIC PARKING BRAKE ACTUATOR

COMPONENTS























ON-VEHICLE INSPECTION
1. INSPECT ELECTRIC PARKING BRAKE ACTUATOR ASSEMBLY

HINT: Using the intelligent tester or Techstream to perform the Active Tests allows relays, VSVs and actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.

(a) Turn the engine switch off.
(b) Connect the intelligent tester or Techstream to the DLC3.
(c) Turn the engine switch on (IG).
(d) Turn the tester on.
(e) Enter the following menus:
(1) Intelligent tester - Select: DIAGNOSIS / OBD / MOBD / CHASSIS / EPB (*) ACTIVE TEST /

HINT: *: Stands for electric parking brake actuator

(2) Techstream - Select: Chassis / Electric Parking Brake / Active Test /
(f) When the vehicle's tires are lifted off the ground and the intelligent tester or Techstream is used to operate the electric parking brake, check the condition of the rear tires.
(g) According to the display on tester, perform the "Active Test"
(1) Intelligent tester

EPB (*):





If the result is not as specified, inspect the electric parking brake actuator.

HINT:
*: Stands for electric parking brake actuator

(2) Techstream

Electric Parking Brake:





If the result is not as specified, inspect the electric parking brake actuator.

REMOVAL
1. RELEASE PARKING BRAKE
(a) With the engine switch on (IG), operate the electric parking brake switch to release the parking brake. Then turn the engine switch off.

HINT: If the parking brake cannot be released, use the luggage compartment's parking brake release tool to manually release the parking brake (refer to the Owner's Manual).

2. REMOVE COWL TOP VENTILATOR LOUVER RH
3. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL

CAUTION: Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to prevent airbag and seat belt pretensioner activation.

NOTICE: After the engine switch is turned off, the HDD navigation system requires approximately 6 minutes to record various types of memory and settings. As a result, after turning the engine switch off, wait 6 minutes or more before disconnecting the cable from the negative (-) battery terminal.
