DTC

B225001

Back Door Closer General Electrical Failure

DESCRIPTION

The back door closer is controlled by the multiplex network door ECU.

The multiplex network door ECU determines the latch position of the back door lock with courtesy light switch assembly based on the combination of signals from the latch switch built into the back door lock with courtesy light switch assembly, back door courtesy switch, sector switch (home position switch) and pawl switch.

This DTC is stored when the back door closer is operating and the sector switch (home position switch) signal indicates that the latch is not in the correct position within the specified amount of time.

When this DTC is output, the multiplex network door ECU suspends back door closer control and power back door control.

DTC No.
