Code P0562 Honda 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 PCM sets a target generating voltage in the range of 12.5 V to 14.5 V and commands the alternator via the LIN line. If the FI MAIN RLY OUT terminal voltage is a specified value for a specified time, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).
