POWER BACK DOOR SYSTEM, Diagnostic DTC:B2222, B2225

DTC Code	DTC Name
B2222	PBD Pulse Sensor Malfunction
B2225	Back Door Motor Clutch Malfunction

DESCRIPTION

A pulse sensor is built into the back door motor 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 is also used to monitor the back door position. If a pulse signal that is out of the normal range is output, the back door motor unit 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).
When an electrical malfunction (open or short) is detected in the clutch circuit of the back door motor unit while the power back door is operating, the back door motor unit stores DTC B2225.
