DTC U0111: F-CAN Malfunction (Powertrain Control Module (PCM)-Battery Condition Monitor (BCM) Module): General Description

The controller area network (CAN) transmits/receives pulsing signals to/from the control modules simultaneously by using two signal lines (CANH and CANL).

When the information is not sent from the battery condition monitor (BCM) module through the F-CAN for a specified time continuously or when the information sent from the BCM module is abnormal and this condition continues for a specified cycle, the powertrain control module (PCM) detects a malfunction and a DTC is stored.
