1. Introduction
1.1 Background
The days of diagnosing and repairing automobiles without a laptop
beside you are quickly fading. Newer vehicles include a large
number of onboard computers that are each dedicated to performing
specific tasks. Common onboard computers in newer vehicle
include the Engine Control Module (ECM), Transmission Control
Module (TCM), Fuel Injection Control Module (FICM), Anti-lock
Brake System (ABS), Body Control Module (BCM) and numerous
other control modules to manage every electronic system from
power door locks to crash data.
Each onboard computer is programmed at the factory with software
enabling it to perform certain tasks. Inside the ECM is software
containing hundreds or even thousands of parameters to control
spark, fuel, idle, cruising, emissions, economy, drivability, and
performance. Likewise, a TCM will have software to control how
the transmission and torque converter function. Sometimes, after
the vehicle is shipped from the automaker, updates are released to
improve emissions, fuel economy, drivability, performance, or
specific bugs in the original software that have caused warranty
issues. Updating this software can be a proactive fix because often
it will resolve problems that a customer hasn’t reported or noticed
yet.
The practice of updating software in these modules is more
commonly known as flash reprogramming. At new car dealerships,
flash reprogramming is relatively straight forward because service
technicians are connected to the automaker and have the expensive,
specialized dealer service tools dedicated to reprogramming. The
independent repair shops have faced a more difficult challenge
because most shops typically service more than one make of
vehicles. This increases the complexity, cost and training required
to operate dozens of different factory service tools.

1.2 J2534 - A Solution Arrives
In 2000, the Environmental Protection Agency (EPA) had been
watching this issue and decided to take action. The EPA requested a
standard be developed within the SAE that led to J2534, a
mandated specification to which automakers who sell vehicles in
the United States must conform. The original J2534 specification
was later updated to J2534-1 in order to support all automakers.
The EPA mandate requires automakers to support aftermarket repair
shops with J2534-1 flash reprogramming for any emissions related
computer modules on a vehicle that can be reprogrammed by a new
car dealership. This mandate took effect for all 2004 and newer
vehicles.
SAE J2534 is a standard devised of two independent parts:
subscription software and a J2534 compliant Pass Thru vehicle
interface. The subscription software comes directly from the
automaker, runs on your shop PC or laptop, and can either be
web-based or CD-based. The subscription fees are charged
differently for each automaker.
1.3 Pass-Thru Vehicle Interface
The second part of the system is a SAE J2534 compliant Pass-Thru
vehicle interface. This device acts as a gateway between the
vehicle’s onboard computers and the technician’s personal computer.
It translates messages from the PC into the protocols used by the
automobile and vice versa.
Performing J2534 reprogramming requires computer knowledge
and experience. The technician will need to operate a laptop or
desktop, the Pass-Thru device, and the reprogramming software.
Operation will also require a good high-speed connection to the
Internet such as DSL, Cable, or T1.

2. Getting to Know MaxiFlash Pro
Thank you for choosing the MaxiFlash
®
Pro Reprogramming
Device! This multi-protocol Pass-Thru vehicle interface is a fully
compliant SAE J2534-1 & SAE J2534-2 (March 2006) device,
specially designed to provide users with convenient PC
communication and ECU reprogramming capabilities on any
modern vehicle diagnostic bus, and offer the most significant
features desired by OEM customers: reliability, fast performance
and flexibility.
2.1 Front Panel
The MaxiFlash
®
Pro Pass-Thru device supports three ways of PC
connection:
Ethernet, USB
and
Bluetooth,
which make PC
communication and vehicle reprogramming all the more convenient
and easy for technicians. These three connection ports to the PC are
available in the front panel of the device.
1)
Status Lights
There are 6 status lights on the front panel of the reprogramming
tool, which indicates the Pass-Thru interface’s working status as
well as the hardware conditions, and are very useful for
troubleshooting the device’s communication or connection to the
Vehicle or PC. Please refer to
Table 1
for detailed description of
the status lights.

TABLE 1—STATUS LIGHTS ON THE FRONT PANEL
Light
Power
Error
Description
Illuminates solid green when powered on.
Illuminates solid red when serious hardware failure
occurs. Please call technical supports for assistance.
Note: This status light turns on automatically every
time when the device is power up, which is a normal
self-test procedure, and it will turn off automatically
later when the device starts working normally.
Bluetooth
Ethernet
USB
Illuminates solid green when connected via
Bluetooth communication.
Illuminates solid green when connected via the
Ethernet serial cable.
Illuminates solid green when the device is properly
connected and communicating with the PC via the
USB cable.
Flashes green when communicating with the
vehicle’s network.
Note: Do not disconnect while this status light is
on! If you interrupt the flash reprogramming
procedure while the vehicle’s ECU is blank or only
partially programmed, the module may be
unrecoverable.
2)
USB Port
Vehicle
The USB port provides the easiest connection between the
device and the PC via a USB cable, and is used to control the
device from the software application running on the PC.
