What is J2534 Flash Programing? 

The days of diagnosing and repairing automobiles without a

laptop beside you are quickly fading.

 Newer vehicles include a larger number of onboard computers that are

 dedicated to performing specific tasks.

From the Common Engine Control Module (ECM), to numerous other control modules

 managing every electronic system from power door locks to crash data.

With J2534 Flash Programming it is possible to update many of these yourself! 

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 customerhasn't reported or noticed yet. Often your customers are not servicing

 their cars at the dealer, missing vital software updates.

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.  

 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 2 which automakers who sell vehicles

 in the United States must conform. 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.

This pay as you go facility is very cost efficient with the TXTs Navigator .

Imagine paying only $35 to the manufacturer to reflash all the modules

in a E90 BMW as our customers have done! 

 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 and good vehicle power supply.
