CAUTION / NOTICE / HINT

NOTICE:

  • Although DTC C060E2A may be stored after entering pad replacement mode, this is not a malfunction.
  • Although DTC C060E2A may be stored after forcibly releasing the parking brake, this is not a malfunction.
  • The electric parking brake may still operate up to 20 seconds after the ignition switch is turned off. Before disconnecting connectors or fuses, turn the ignition switch off and wait 20 seconds or more.
  • After replacing the skid control ECU (brake actuator assembly), perform acceleration sensor zero point calibration and store system information memorization.

  • When replacing the skid control ECU (brake actuator assembly), operate the electric parking brake switch (integration control and panel assembly) as the parking brake indicator light blinks when the ignition switch is first turned to ON.

PROCEDURE

1.

CHECK DTC

(a) Using the Techstream, check for DTCs other than DTC C060E2A.

2.

INSPECT NO. 2 PARKING BRAKE WIRE ASSEMBLY

(a) Turn the ignition switch off.

(b) Make sure that there is no looseness at the locking part and the connecting part of the connectors.

OK:

The connector is securely connected.

(c) Disconnect the NN6 and N57 No. 2 parking brake wire assembly connectors.

(d) Check both the connector case and the terminals for deformation and corrosion.

OK:

No deformation or corrosion.

(e) Measure the resistance according to the value(s) in the table below.

(b) Turn the ignition switch off.

(c) Check that the rotating parts are not seized or the actuator is not spinning freely.

(1) Check that the parking brake actuator assembly LH is installed properly to the rear brake caliper and that it is not spinning freely.

For the parking brake actuator assembly LH removal procedure: Click here 2019 - 2024 MY RAV4 RAV4 HV [11/2018 -        ]; PARKING BRAKE: ELECTRIC PARKING BRAKE ACTUATOR: REMOVAL

(2) Check that there is no damage to the rotating parts from the parking brake actuator assembly LH to the rear brake caliper.

(3) Inspect the parking brake actuator assembly LH and check that it operates correctly.
