DESCRIPTION
This article equips technicians with the knowledge and steps needed to efficiently replace and program N9/N10 and N13
modules, while addressing potential baud rate incompatibility issues between the replacement module and the vehicle.
SERVICE INFORMATION
Table Of Contents
Introduction
The history of baud rate at International
, and why it matters.
Identifying Vehicle Baud Rate
You MUST know the baud rate of the vehicle you are working on so you can
obtain the correct module.
Use Correct Module
Certain modules can have their baud rate switched; others cannot. Use this
information to obtain the correct module.
Determine Replacement
Module Baud Rate
The baud rate of the module MUST match the baud rate of the vehicle.
Switching Module Baud Rate
This covers the programming processes that are needed in order to switch
the baud rate of a module.
Introduction
It is possible to replace a module without encountering problems. However, you are likely here because you have
encountered issues programming a replacement module (or a test module) for an N9/N10 or N13 engine. Before
moving on to the programming processes that resolve these issues, it is important to understand what causes them baud rate.
The term "baud rate" refers to speed of communication on the data link. Higher baud rate numbers refer to faster
communication speeds. It is also important to understand that a 250k baud rate module will not work on a 500k vehicle and vice versa. We need to start with some facts.
1. N9/N10 engines were built from 2014-2017.
2. N13 engines were built from 2013-2017.
3. International built vehicles with a 250k baud rate from 1994-2015.
4. International started building vehicles with 500k baud rate in August 2015 - right in the middle of N9/N10/N13
production.
This means that early N9/N10/N13 engines use a 250k baud rate and late ones use 500k. It is important to make
sure we use replacement modules with the correct baud rate for the vehicle we are working on. A 250k ECM will
not be detected on a 500k vehicle - and vice versa. Using a module with the wrong baud rate can result in a
NavKal error 8 (N9/N10 & N13) or NavKal error 12 (N13).

Note: A green plug (on the end of a communication cable) can connect to both

receptacles.
