NEWS!   Diagnostics over J2534 is here!
The newest public release of GM's Diagnostics Software, GDS2 version 11.0.09412, now works with DrewTech's CarDAQ-M and MongoosePro GM II. GM will not be providing technical support for aftermarket devices with GDS2 so customers will be encouraged to contact DrewTech directly for support.

Drew Tech products support GM diagnostics with Tech2WIN 

General Motors is the latest OEM to annoumce factory/dealer level diagnostics support over J2534 pass-thru and Drew Tech tools are the exclusive tool chosen for full compatibility.  

The list of OEMs now supporting full diagnostics over J2534 tools now includes Toyota, Volvo, BMW & General Motors

The new J2534 pass-thru interface from Drew Technologies is the most adavanced, complete, and upgradable J2534 device available today. Designed to keep up with OEM technology that is constantly changing, the CarDAQ-M has expansion modules available to keep it on the brink of the latest automotive technology.

The CarDAQ-M package includes: ul>
  • CarDAQ-M J2534-1 / J2534-2 vehicle interface
  • Installation CD with device driver (J2534 compatible)
  • CDP-J1962 vehicle interface cable
  • Ethernet Cable
  • USB Cable
  • J2534 has become an invaluable service tool for any aftermarket shop in the last 5 years. Automotive electronics are becoming more complex. Manufacturers are adding more communication channels and more electronic control units to modern vehicles. The modular/expandable nature of the CarDAQ-M allows you as a technician to purchase new expansion modules as new technologies present new service opportunties.

    Introducing the new CarDAQ-M! The new J2534 pass-thru interface from Drew Technologies is the most adavanced, complete, and upgradable J2534 device available today. Designed around the idea that automotive technologies are changing rapidly, the CarDAQ-M has expansion modules available to keep it on the brink of the latest automotive technology.

    The EPA standard for independent shop reprogramming is J2534-1, but since automakers recognized that the J2534-1 standard did not cover all of their needs for the future. This lead to the development of J2534-2, a set of optional extensions. The CarDAQ-M from Drew Technologies is expandable to support the J2534-2 extensions. Drew Technologies is also working with the SAE and automakers to establish a SAE J2534-3 standard for compliance. This support protects your investment.

    SAE J2534-1 API is the "Recommended Practice for Microsoft Windows 32-Bit Application Programming Interface for Pass-Through Vehicle Reprogramming".

    Vehicle manufacturers are required to provide a Windows software application for reprogramming their model year 2004 and beyond vehicles using a J2534-1 capable interface (e.g. Mongoose, CarDAQ-Plus, or CarDAQ-M). This standard and associated EPA requirements will give all vehicle service/repair facilities, not just dealers, the ability to perform in-field ECU software updates.

    If you want hands on training on J2534, an engineer from Drew Technologies teaches SAE class C0733 "Understanding and Using the SAE J2534-1 API to Access Vehicle Networks". To learn about this class, email

    In addition to reprogramming, J2534 supports diagnostics and calibration. The API provides protocol-independent functions to:

    • Read and write messages
    • Establish periodic messages
    • Perform filtering, and assert ECU reprogramming voltages.

    Having access to SAE J2534-1 software and tools are important for several reasons. First, diagnosing and repairing vehicles often requires reprogramming or reflashing the vehicle with the latest update. After a vehicle is assembled and sold at a new car dealership, the automaker’s engineering groups often fix common problems found at the dealership by releasing a new reflash. The reflash is not a recall, and therefore most vehicles on the road will not get the update unless they are brought in to the dealership for servicing. These reflashes could fix transmission shifting problems, hesitation, rough idle, drivability, check engine lights, emissions quality, poor performance, or any of a number of other problems. Without the reflashing capabilities, independent repair shops may spend time and money trying to repair an issue with hard parts that cannot be repaired without a calibration flash update.

    The Second reason a repair shop should have a SAE J2534-1 device is to offer their customers flash updates as an up sell. Even if the customer does not believe they are experiencing a problem with their vehicle, they may see some benefit in performance, drivability, or even fuel economy by getting their vehicle updated to the latest available calibration flash. It also serves as good preventative maintenance to update the calibration flash and avoid any problems that it was intended to fix.

    Don't forget to keep your battery at full charge while programming!
    Any shop which offers reflashing / reprogramming would be remiss in their duties to NOT have a high quality professional battery maintainer to keep the battery at full power and with clean voltage.  Whether you're performing factory OEM module programming via J2534 or custom tuning with HPTuners, EFILive, Sniper, Tactrix or Evoscan;   All agree that a professional high quality current must be maintained on the vehicle battery throughout the process.  The CTEK MULTI US 25000 (Part No. 56-674) is an 8-step, fully automatic primary switch mode professional battery charger / maintainer. A powerful charger for 12V batteries that require rapid charging such as in garages, RV’s, boats and of course cars. Unlike old traditional battery chargers CTEK chargers are designed with focus on simplicity, safety and flexibility.
