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 set DTC B2222.
- If DTC B2222 is set, 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).
