In addition to being able to retrieve and clear DTCs, a Tech2 can also be used to reset service messages, alter locking logic, recalibrate the speedometer (when 16' wheels are changed to 17' or vice versa), clone security chips for keys or update engine management software. The Tech2 can retrieve DTCs: example P1805 and they can be looked up with the Workshop Information System (WIS) in the case of 9-5s or with later 9-3s, it pays to have the Tech2 connected directly to a laptop, so the fault can be read directly by WIS.

Sensors on the pBus are interrogated all the time by the Trionic management system and if an unexpected value is returned or no signal is received, a diagnostic trouble code (DTC) is triggered. The iBus is basically concerned with instrumentation while the pBus related to the power unit, monitoring the engine and transmission. Now, cars like the 9-5 have two interconnected bus systems: iBus and pBus. Then, turning on the ignition and waiting for the management light to flash a certain number of times gave technicians a good idea what was wrong. It is hard to work on SAAB cars regularly without access to a Tech2 scan tool because the engine management systems have evolved since the days of the early 9000. The scan tool is connected to the vehicle via the On Board Diagnostic (OBD) or CANBUS (controller area network bus) socket and draws power from the car.

In effect, this is a hand held computer which uses PCMCIA cards onto which software is loaded for the appropriate GM family model (SAAB, Vauxhall, Suzuki etc). The вЂDaddy' of all special SAAB tools, however, is the AD 400 Tech2 Scan tool. In 2006, the Vetronix Aftermarket division merged with Bosch Automotive Aftermarket, responsible for supply, sales and logistics of automotive parts for service of the vehicle. In 2003, Vetronix was acquired by ETAS, a supplier of standardized development and diagnostic tools for electronic control units. Vetronix purchased the Tech2 manufacturing rights from HP.

The original GM Tech2 was made by Hewlett Packard and used Vetronix software. The Tech2 is not a engine tuning tool but is able to give you good insights on the status of the car. Also the Tech2 is able to set brand/type specific settings. While generic scanners can show and decode error codes, the Tech2 has the ability to get into the details of the error. The Tech2 is a scanning device which is able to let you deep dive into the internals of the various systems in your vehicle.
