CarDAQ Plus Reflashing

CarDAQ Plus - PassThru J2534 Vehicle Reflash Hardware

(CDP-J1962 Interface cable required to connect to OBD II data plug on vehicle, add as option in shopping cart)

CarDAQ Plus, Compatible with TIS, TIS2WEB, WEBFLASH, Toyota Techstream lite & more

The CarDAQ Plus is the ultimate interface for communicating with newer automobiles, heavy duty trucks, and CAN networks. It has both Ethernet and USB connectivity to a PC, a built-in operating system for running internal programs, protocol support for all modern vehicles, and six analog inputs. No other J2534 tool on the market has the performance and capabilities of the CarDAQ-Plus. It is upgradeable thru firmware updates and expansion slots. The CarDAQ family is the most talked-about J2534 interface out there.

 J2534-1 Reflashing Applications for Independent Repair Shops

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, that all automakers must support with their vehicle reflashing applications.

CarDAQ Plus Features

CarDAQ Plus was built for real world conditions. It performs the standard Pass-Thru J2534 functionality, adds an internal 200MHz embedded Linux host, a CompactFlash slot, and an internal web server for thin-client applications. In addition to acting as a laptop-to-vehicle Pass-Thru device, it can also host diagnostic and data logging applications on-board.

Compact Flash expansion for Wireless 802.11, GPS, and more

The CarDAQ Plus has one internal and one external Compact Flash slot that can be used simultaneously. For wireless connectivity, we interface with off-the-shelf 802.11 WiFi compact flash cards. This is the same proven technology found in most modern laptops. It provides the speed, range, and reliability needed for wireless applications. The Compact Flash expansion slots may also be used for other CF peripherals, such as GPS receivers, expanded storage, modems, and any other CF card that supports Linux. The CarDAQ-Plus will support up to 8GB of memory per Compact Flash slot.

Remote Diagnostics and Standalone operations

CarDAQ Plus runs it's own operating system, embedded Linux, which allows it to be used as a standalone tool without a PC attached during operation. The Linux installation includes a file and web server which could simplify development of remote diagnostics and management applications. Imagine writing your own C/C++ application to perform an on-road test, then use 802.11 WiFi to wirelessly download a vehicle's data as soon as it re-enters the repair facility. Your program could access GPS compact flash card to capture location information about the test drive, or use a cellular modem and download telemetry from live tests! For standalone applications, this provides the features of a PC host and a Pass-Thru device all in one package.

Linux-SDK™ - Many Drew Technologies products feature embedded Linux. So our customers can get the most out of this flexible platform, Drew Technologies is now offering this application development kit. This kit will help developers write application software more quickly that can be compiled and run on AVIT, CarDAQ-Plus, ScanDAQ, and DashDAQ.

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.

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 flash updates as an up sell to customers. 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.

J2534-2 Support

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-Plus from Drew Technologies supports many 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. Supported J2534-2 extensions include:

•    Single Wire CAN
•    CAN Mixed Mode
•    A/D Inputs
•    Pin Switching
•    Discovery
•    Extended Pass-Thru input control for Device Configuration Parameters
•    Extended Programming Voltage Support
•    UART Echo Byte Protocol

 Software Supported

Use any Pass-Thru (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.

Additionally, CarDAQ-Plus can host Pass-Thru (J2534) applications on the internal embedded Linux processor. Use your favorite language, including: TCL, Perl, .Net, Java, or C.

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

Note:  Drew Technologies (currently) does not provide software applications.  The buyer needs to obtain the specific make software applications. The SAE J2534 applications are by subscription from each vehicle manufacturer and OBD-II scan tool software is available on our Software Category page.
