Dtc B2222 Pbd Pulse Sensor Malfunction

DESCRIPTION

INSPECTION PROCEDURE

CHECK DTC OUTPUT

DESCRIPTION

1. A pulse sensor is built into the power back door unit assembly (power back door ECU) to detect foreign objects and the back door position. The pulse sensor monitors the operating speed of the back door while the power back door is in operation 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 unit assembly (power back door ECU) will set DTC B2222.
   
2. If DTC B2222 is set, the power back door system will be turned off. Thus, the back door will be switched to manual operation mode (not electrically controlled) and can be moved freely.
   
3. In order to restore the power back door system to normal operation mode, first solve the problem indicated by DTC B2222 and then manually close the back door fully (reset operation).
