J2534 FAQs


Check out DG Technologies J2534 Standard Automotive Reprogramming Tools Here:




Reprogramming is the process of replacing the existing software in a vehicle controller with new software by electronically transferring approved calibration files from a vehicle manufacturer’s website.  (也称为重闪、闪动、编程或重新配置.)


1. Automobile manufacturers are constantly making changes to their controller software – making cars more efficient, 修复已发现的问题, 微调组件和系统, 随着汽车的老化,更新切割点, 解决怠速粗糙、难启动等问题, 修复与排放有关的问题以及其他许多问题.

2. New controllers replaced in a vehicle require programming to match the exact specifications and option list on the car being repaired.

3. Many of the Technical Service Bulletins (TSBs) issued by automobile manufacturers require reprogramming with the latest software updates to repair problems that are occurring with vehicles on the road even after their warranties have expired.

Isn’t reprogramming just for cars that are still under warranty so only dealers will need this capability?

Maybe you thought only cars still under warranty are being reprogrammed and it’s just not worth your while.  目前,路上有超过1亿辆汽车支持J2534重新编程.  Studies indicate that 7 out of 10 vehicles on the road require a calibration update.

Auto Manufacturers are constantly updating controller software to solve problems such as false DTCs, hesitation, rough idle, emissions problems, hard starting, 燃油经济性差等等. 这些问题困扰着许多不再保修的汽车.  Your competitors are making money repairing these cars by J2534 reprogramming.  You should be too!!


What is J2534?

SAE J2534 is a standard for communications between a computer and a vehicle. Government regulations require all automakers provide a J2534 service to EVERYONE in the U.S. 用于重新编程(也称为重新编程)排放相关控制器.  如果您拥有J2534 Pass Thru设备, you can reflash and, in some cases, 诊断具有出厂功能的车辆.

DG Technologies的新VSI NxGen是J2534直通器件.

什么是J2534 Pass Thru器件?

一种J2534直通装置, 例如VSI NxGen, is an interface that acts as a gateway between a vehicles controller and the technician’s PC.  Its purpose is to translate the messages back and forth between the PC and controller into a protocol that is understood by the vehicle.


Computers and software in cars have been expanding at an exponential rate.  There are now over 100 Million reprogrammable controllers on the road today.  Updating vehicle controller software is becoming one of the leading solutions for vehicle repairs.  重新编程可能是解决这些问题的唯一方法:

  • Driveability
  • Fuel efficiency
  • Power loss
  • Fault codes
  • 机械零件耐久性


J2534重新编程正在成为一个必不可少的车间工具.  Studies indicate that 7 out of 10 vehicles on the road require a calibration update. 使用J2534重编程器,您可以:

  • 修理有上述问题的汽车
  • 通过提供以前发给经销商的服务来增加利润
  • 提供留住客户所需的服务


As of 2004, all new vehicles must support the SAE J2534 (reprogramming) specification as mandated by the EPA.

The EPA mandate also requires OEMs to support aftermarket repair shops with J2534 flash programming for any emissions related controllers on a vehicle that can be reprogrammed by a new car dealership.

虽然这只适用于2004年的车辆, many OEMS offer support for older vehicles and other types of controllers. Be sure to check out the vehicle manufacturers websites to find out which vehicles they support reprogramming for.


What controllers can be programmed is determined by the vehicle manufacturer. 并非所有制造商都提供对所有控制器的访问.



A VSI NxGen package will give your shop a greater earning potential by providing job profitability, 更多的“店内”服务和质量控制.

这是如何产生快速回报的呢 & profit for you:

  • 让更多的工作和利润留在国内
  • 控制维修质量=提高顾客满意度
  • 减少车辆维修时间=腾出时间进行更多的维修
  • 增加商店的能力=更多的生意




What is it costing you to work on a driveability issue for a long time only to find out it is a reflash issue and you have to send it out?

你损失了多少生意 that is already coming to your shop that you may not have known even existed?

你损失了多少生意, when you have to send your customers somewhere else and many may never return?

How do you plan on fixing issues such as a False DTC when the only fix is to reprogram the vehicle?


OEM数据订阅直接从OEM网站获取. 最初大多数都是CD,但现在它们都是基于网络的.  Subscription fees vary by OEM and have several payment options: per-vehicle, 24 hours, 72 hours, weekly, monthly, or annually.

You can change some values like tire size and pinion factor depending on the vehicle and whether the vehicle supports this capability.  As far as changing horse power or torque or anything of this nature this is not possible.


DG Technologies的VSI NxGen不是性能工具. They are used to re-flash the vehicles computer when there are updates available from the vehicle manufacturers.

这些更新被称为TSB的或技术服务公告. If the vehicle manufacturers find a way to better the performance of a vehicle they will release these TSB’s and you will have to re-flash the vehicle computer to update it.

The only way that the performance of the vehicle will be changed is if this is included in the TSB’s that are released from the vehicle manufacturers. Depending on what’s in the TSB than the shift points or something could change.
