Drew Technologies leads the vehicle diagnostic and reprogramming market. Ford Motor Company, General Motors, and Volvo have all verified the CarDAQ2534™ as being the fastest vehicle reprogramming interface available for J1850VPW, J1850PWM, and CAN networks.
Since 1996, Drew Technologies has provided vehicle network interfaces, custom electronics, and engineering services to the automotive and telecommunication industries. These products are engineered to operate under harsh in-vehicle and assembly-line conditions.
CarDAQ2534™, CarDAQ-Plus™, and ScanDAQ™ comply with the
SAE J2534 (Feb 2002) and
SAE J2534-1 (Dec 2004) specifications for PassThru vehicle
reprogramming. All industry standard vehicle protocols are supported
including: CAN / ISO15765, J1850VPW, J1850PWM, ISO9141, Keyword2000.|
Drew Technologies, in cooperation with auto manufacturers, has verified compatibility with all major ECU re-flashing software including:
Service Programming System
(TIS) ||Ford Motorcraft Webflash||DaimlerChrysler PassThru Programming System||Volkswagen Erwin|
Drew's Flagship products, CarDAQ-Plus and ScanDAQ lead the next-generation of PassThru vehicle network interfaces. In addition to functioning as a PassThru vehicle interface, these devices can also host programs internally on an embedded Linux controller.
Drew Tech recently released the CarDAQ-DV for 3rd party fleet and application integrators. The CarDAQ-DV features embedded Linux on a 200MHz processor, built-in wireless, wired ethernet, and support for all J2534-1 protocols including ISO15765 (CAN), J1850PWM (Ford SCP), J1850VPW (GM Class 2), ISO9141 (KWP2000), and Chrysler SCI. The embedded Linux platform allows developers to host applications on the CarDAQ-DV so it can operate without a PC connected. A licensable diagnostic and data logging library will also be available to easily retrieve generic and enhanced PIDS, DPIDS, and DMRs.
This product will allow programmers to easily integrate vehicle data and diagnostics into 3rd party applications without knowing automotive-specific protocols and diagnostics information.
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.
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.
