OEM J2534 Reflashing Applications

Servicing newer, more increasingly complicated vehicles has put independent repair shops at a disadvantage against auto dealerships that have access to the latest service tools and knowledge databases. Accurately diagnosing and repairing many of these newer vehicles used to require full access to expensive factory service tools. The EPA recognized the independent repair shop’s need for access and mandated that all OEMs comply with the SAE standard J2534-1. The SAE J2534-1 standard defines a uniform hardware device, like the Drew Technologies CarDAQ-Plus, ScanDAQ and some of the Mongoose versions that all automakers must support with their vehicle reflashing applications.

SAE J2534 Pass-Thru hardware by Drew Technologies

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.


Software Supported
Use any PassThru (J2534) compliant application. If you are an independent software vendor and want to add J2534 support to your application, please email support@drewtech.com for assistance
PCMSCAN - Allows viewing, charting, logging, and playback of diagnostic data in real time. Realistic looking gauges can be moved, resized, and laid out to resemble your own dashboard. Display English or Metric units. Read stored Diagnostic Trouble Codes (DTCs), clear the check engine light, and test emissions related systems.

Drew Technologies also provides an application programmer interface (DLL) for OEMs, integrators, or end-users to develop their own PassThru (SAE J2534) applications. Create your own applications in LabVIEW™, C or Visual Basic

NEWS!:  Drew Technologies has released a JVCI software library of re-usable components designed to make building 3rd party applications a snap. With this JVCI library, applications can be easily assembled that will offer ultra-highspeed datalogging and enhanced diagnostic parameters. Following the release of this JVCI code will be an updated API for PCMSCAN which will place this high-speed enhanced parameter diagnostic power in the hands of consumer level DIY mechanics & tuners!
