Keyword 2000 Protocol - Coat Application" and "ISO 15765 part 3 "Diagnostics on CAN - Application

layer services".

This document describes ECU realignment operations, when defects have been identified, and when

those may be corrected through downloading of a new software version.

These realignment operations shall be possible:

• on the vehicle, that is without dismantling the calculator,

• using the vehicle diagnostic bus,

• via a standard diagnostic plug,

• without having to apply an external specific voltage.

The objective is to use the realignment means and procedures:

• in the after-sales networks,

• in assembly plant parks,

• on ECU prototypes used in development phase.-This document originates from ISO international Standards 14230, Section 3 "Diagnostic System-
