P0602 HONDA Description
The Engine Control Module (ECM) is equipped with an update program to update its control program. The programs in the CPU of the ECM are classified as an ECM program (update-capable program) and a program for the update function (non-updatable program). The program update only updates the ECM program.
When the ECM 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 ECM stores a Diagnostic Trouble Code (DTC) that indicates the update is not finished.
