ELECTRIC PARKING BRAKE SYSTEM PRECAUTION


  1. IGNITION SWITCH EXPRESSION

    Tech Tips

    The type of ignition switch used on this model differs according to the specifications of the vehicle. The expressions listed in the table below are used in this section.

    Expression Ignition Switch (position) Engine Switch (condition)
    Ignition Switch off Off Off
    Ignition Switch ON ON On (IG)
    Ignition Switch ACC ACC On (ACC)
    Engine Start START Start

  2. DTC PRECAUTION


    1. Some DTCs will not be cleared by just replacing the malfunctioning parts. If a DTC is still output after completing a repair, turn the ignition switch off before beginning the clear DTC procedure.

      Note

      If a DTC for a malfunctioning part is output again after it was cleared, then it has been stored again.

  3. CAN COMMUNICATION SYSTEM PRECAUTIONS


    1. The CAN communication system is used for data communication between the electric parking brake ECU and other ECUs. If there are any problems in the CAN communication system, the corresponding DTCs for the CAN communication system are output.

    2. If any CAN communication system DTCs are output, repair the malfunction in the communication system and then troubleshoot the electric parking brake system while data communication is normal.

    3. In order to enable CAN communication, a specific type of wiring is used for the CAN communication lines. The wiring used for each communication line is a twisted pair of wires that have an equal length. A bypass wire should not be used as the data being transmitted will be corrupted.

  4. PRECAUTION FOR ELECTRIC PARKING BRAKE SERVICING


    1. Before performing work, turn the ignition switch off and wait approximately 20 seconds to make sure that the parking brake cannot operate.

    2. Do not drop the electric parking brake actuator. If the electric parking brake actuator is dropped, it cannot be reused.

    3. Do not carry the electric parking brake actuator by the cable.

    4. for M/T:


      1. After adjusting or replacing the brake pedal stroke sensor (clutch pedal stroke sensor) and performing brake pedal stroke sensor (clutch pedal stroke sensor) zero point calibration (See page ), perform clutch engagement point learning (for EB60: See page , for EC60: Click here.
