B2222

DTC B2222 PBD PULSE SENSOR MALFUNCTION

CIRCUIT DESCRIPTION

DTC Detection Condition:

- A pulse sensor is built into the back door for a jam and foreign object detection and for back door position detection. The jam and foreign object detection feature of the pulse sensor monitors the operating speed of the back door while the power back door is in operation. The back door position detection feature of the pulse sensor monitors the back door location. If the back door position detection feature outputs a pulse signal that is out of the normal range, the power back door ECU will set DTC B2222.
- If DTC B2222 sets, the power back door system will be turned off. Thus, the back door can be moved freely and 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 manually close the back door fully (reset operation).
