Title: PARKING BRAKE: ELECTRIC PARKING BRAKE SYSTEM (w/ Vacuum Brake Booster): C060962; Electric Parking Brake Switch Signal Compare Failure; 2019 - 2024 MY RAV4 RAV4 HV [11/2018 -        ]

DTC

C060962

Electric Parking Brake Switch Signal Compare Failure

DESCRIPTION

When the electric parking brake switch (integration control and panel assembly) is pulled, a lock request signal is sent from the skid control ECU (brake actuator assembly) to the parking brake actuator assembly. When the electric parking brake switch (integration control and panel assembly) is pushed, a release request signal is sent from the skid control ECU (brake actuator assembly) to the parking brake actuator assembly.

DTC No.

WIRING DIAGRAM

CAUTION / NOTICE / HINT

NOTICE:

  • If the electric parking brake switch (integration control and panel assembly) is held near the lock position but not fully in the lock position for 1 second or more, a DTC may be stored due to one of the two contacts being ON while the other is OFF. (This is not a system 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.

READ VALUE USING GTS (EPB SWITCH)

(a) Operate the electric parking brake switch (integration control and panel assembly) and check that the value of "EPB Switch" in the Data List changes between Apply and Release in accordance with the operation of the switch.

Diagnostic Note

EPB Switch

Electric parking brake switch (integration control and panel assembly) input

Neutral, Apply, Release or Unknown

Neutral: Lock switch and release switch are off

Apply: Lock switch on

Release: Release switch on

When not normal, electric parking brake switch (integration control and panel assembly) release side system may be malfunctioning

HINT:

EPB stands for electric parking brake.
