P16D7 HONDA 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 F-CAN communication between the FI CPU and the CVT CPU inside the powertrain control module (PCM) is abnormal and F-CAN communication is interrupted for a specified time, a malfunction is detected and a DTC is stored.
