Suzuki has used several factory diagnostic systems, including the shared Tech 1 and Tech 2, Suzuki SDT and Suzuki SDT-II. Coverage depends on the vehicle, market, software and service operation.
Tech 2 and shared hardware
A Suzuki Motor USA bulletin specifically describes Tech 2 software and Techline Connect access for the 2007–2009 XL7. This example does not imply that the GM software card covers other Suzuki vehicles, or establish a global year range. Suzuki Motor USA bulletin SI-32.
SDT and SDT-II
A Suzuki service bulletin identifies the earlier Suzuki SDT scan tool, while the Suzuki SDT-II operator's manual describes PC software and a vehicle communication interface. The manual calls SDT-II “Smart Diagnostic Tester type II” and describes functions such as fault-code display, data lists and active tests.

As a specific later application, Suzuki's India-market Grand Vitara hybrid battery manual instructs use of SDT-II for a data-list reading. That example establishes a tool application for that procedure, not comprehensive support for all hybrids. Suzuki Grand Vitara hybrid battery manual.
In Australia, the Australian Automotive Service and Repair Authority lists SDT-2 hardware and diagnostic software separately. Confirm the appropriate regional subscription, VCI, vehicle coverage and any security authorisation before carrying out a service operation. AASRA Suzuki information.
Earlier Tech 1 application
The Tech 1 also used a Suzuki ECM 6.0 cartridge application for specified engine and automatic-transmission systems. The manual excludes North American OBD-II vehicles from model year 1996 onwards from that particular application. Suzuki ECM 6.0 operator's manual.
