DTC P0602: Powertrain Control Module (PCM) Programming Error

General Description

Courtesy of HONDA, U.S.A., INC.

The system notices the customer that the powertrain control module (PCM) software reprogramming is failed due to power shut-off during reprogramming. The reprogramming determination software which is located on the non-reprogrammable area determines the status of the reprogramming. If the software determines as "reprogramming not completed", the PCM detects a malfunction and stores a DTC.
