DTC

B2222

PBD Pulse Sensor Malfunction

DESCRIPTION

  • A pulse sensor is built into the power back door drive unit to detect foreign objects and the back door position. The pulse sensor monitors the operating speed of the back door to detect foreign objects. The pulse sensor also monitors where the back door is to detect the back door position. If a pulse signal that is out of the normal range is output, the power back door drive unit (power back door ECU) will store DTC B2222.
  • If DTC B2222 is stored, the power back door system will be turned off and the back door will be switched to manual operation mode (not electrically controlled).
  • In order to restore the power back door system to normal operation mode, first solve the problem indicated by DTC B2222 and then fully close the back door manually (reset operation).

    DTC No.
