Overview

The CarDAQ2534 is a network interface for all OBD-II (1996+) vehicles. Popular applications include: accessing vehicle sensors and modules, reprogramming ECU firmware, and updating calibration settings. Ford Motorcraft endorses the CarDAQ2534 for ECU reprogramming, and it is still the fastest PassThru device in the marketplace.

For fully J2534 compliant hardware, please consider our newest device CarDAQ-Plus. It adds the Chrysler SCI protocol and a routable, adjustable programming voltage.

Features

CarDAQ2534 is the market's most rugged PassThru (J2534) device; ideal for in-vehicle or assembly-line applications. It features: sealed connectors, an aluminum case, optically isolated host interfaces, 6-15 V operating voltage with reverse battery protection, and an industrial (-40 to +80 C) operating temperature range. Compare that with the competition's delicate PCMCIA dongles, plastic cases, and laboratory-conditions equipment. Only CarDAQ2534 can handle harsh in-vehicle and assembly-line environments.

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 products, 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.

Software Supported

Use any PassThru (J2534) compliant application (V2, Web Flash, SPS/DPS, OEM mandated reprogramming.) Create your own applications in LabVIEW™, C or Visual Basic.

Note: Drew Technologies provides an application programmer interface (DLL) for OEMs, integrators, or end-users to develop their own PassThru (SAE J2534) applications.
