Code P065A 2021 Honda CR-V Description

Driven by the engine, the alternator generates electricity according to the commands from the Powertrain Control Module (PCM). The Local Interconnect Network (LIN) line is connected to the alternator and transmits/receives information to/from the PCM. The voltage regulator in the alternator self-diagnoses itself, and by the PCM demands, the results are transmitted via the LIN line. If the self-diagnosed results are judged as generation unable or alternator rotation stop, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC). Alternating Current Generator (ACG)
