ENGINE HOOD / DOOR: BACK DOOR CLOSER SYSTEM: B2215: Back Door Closer Switch Malfunction

DTC B2215 - Back Door Closer Switch Malfunction

DESCRIPTION

This DTC is output when the neutral switch in the back door has a malfunction. This neutral switch detects if the back door is in the open/close position and sends a position signal to the power back door ECU.





NOTE: The power back door ECU records the back door positions in the memory. In the case where any of the batteries, fuses, power back door ECU and power back door drive unit are removed and then reinstalled, the power back door ECU loses the memory of the door positions. In such a case, resetting the power back door system is necessary. Refer to the resetting operation. Back Door Closer System
