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
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 shopï¿½s 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
NEWS! Diagnostics over J2534 is
here!Drew Tech products support GM diagnostics
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 &
now... General Motors!

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
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 PassThru device all in one
Linux-SDKï¿½ - 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.

newer, more increasingly complicated vehicles has put independent

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 shopï¿½s 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 automakerï¿½s
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
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
