REPAIR" procedure.

VERIFICATION OF VEHICLE REPAIR

Refer to DTC B1910.

DTC B2331 DRIVE DOOR UNLOCK ACTUATOR ERROR

COMPONENT LOCATION

Refer to DTC B1910.

GENERAL DESCRIPTION

DDM is a node of CAN communication system which consists of IPM. FAM, RAM, ADM, IMS. Main
function of DDM is lock/unlock of door and window, adjusting position and fold/unfold of outside mirror. Door
lock actuator consists of motor and monitoring switch. According to Switch signal of DDM, Door lock actuator
operates motor to lock/unlock door and monitoring switch delivers result to DDM by voltage value.

DTC DESCRIPTION

The ECM sets DTC B2331 if there's short circuit in driver door unlock actuator circuit harness.

DTC DETECTING CONDITION

Refer to DTC B2330.

MONITOR DTC STATUS

1. Connect scan tool to Data Link Connector (DLC).
