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
2
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.
