CAUTION / NOTICE / HINT

NOTICE:

  • Although DTC C06132A may be stored after entering pad replacement mode, this is not a malfunction.
  • Although DTC C06132A 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.

INSPECT NO. 1 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 oO3 and o1 No. 1 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.

INSPECT REAR BRAKE AND PARKING BRAKE ACTUATOR ASSEMBLY RH (CHECK FOR ROTATING PARTS THAT ARE STUCK AND FOR FREE SPINNING ACTUATORS)

(a) Enter rear brake pad replacement mode.

Click here

(b) Turn the ignition switch off.

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

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

For the parking brake actuator assembly RH removal procedure:
