DTC P16D5: F-CAN Malfunction (Internal Malfunction): 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 CVT CPU via the F-CAN and this condition continues for a specified time or when the information sent from the CVT CPU is abnormal and this condition continues for a specified cycle, the powertrain control module (PCM) detects a malfunction and stores a DTC.
