Chapter 10 ECU Reprogramming
Notes:
•
This function enables the program installed in ECU to be reprogrammed using MUT-III.
•
As VIN or other ECU setting information is not erased by this reprogramming,
you do not need to rewrite VIN.
10-1. Process Flow Chart
Reprogramming by K-Line communication system
(Models except for Colt in EU)
-There are 7 different ways for ECU reprogramming as shown below.
-Procedure (a) is recommendable due to the most simple in operation.
-File extension code is “ .rpg”.

Reprogramming by CAN communication system
(Colt:Z30# model)
-This is the only way for reprogramming Colt:Z30#car.
-This procedure allows you to select an arbitrary system (ECU) to reprogram as required.
-File extension code is “ .cff”.
