Code P0602 2020 Honda CR-V Description

The Powertrain Control Module (PCM) is equipped with an update program to update its control program. The programs in the Central Processing Unit (CPU) of the PCM are classified as a PCM program (update-capable program) and a program for the update function (non-updatable program). The program update only updates the PCM program. When the PCM power is turned off during an update, the power for the update function is lost, and the update process stops. When the program update is stopped before it is completed, the PCM stores a Diagnostic Trouble Code (DTC) that indicates the update is not finished.
