Standalone operations
ALLSCANNER runs it"s own operating system which allows it to be used as a standalone tool without a PC attached during operation. Imagine writing your own C/C++ application to perform an on-road test, then use 802.11A/B/G 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 package.

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 ALLSCANNER® VCX®, 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.

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 ALLSCANNER® VCX® from Yoho Technology supports many J2534-2 extensions. Supported J2534-2 extensions include:
* Single Wire CAN
* CAN Mixed Mode
* A/D Inputs
* Pin Switching
