P16D5 Code - F-CAN Malfunction Internal Malfunction
Quick Answer
The Controller Area Network (CAN) transmits/receives pulsing signals to/from the control modules simultaneously by using two signal lines (CANH and CANL). Common causes include Controller Area Network (CAN) Communication, Faulty Powertrain Control Module (PCM), Powertrain Control Module (PCM) harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
