The SZ Viewer A1 application is specifically designed for Suzuki vehicles, enabling users to interface with various control modules using an ELM327 adapter. This tool supports both standard OBDII protocols and Suzuki-specific protocols, such as those utilized via the K-Line and CAN bus, to read and reset Diagnostic Trouble Codes (DTCs). This includes both extended and historical codes across numerous Suzuki control modules.
SZ Viewer A1 extends its compatibility to Japanese Domestic Market (JDM) Suzuki vehicles, which might not support OBDII protocols, ensuring comprehensive coverage for Suzuki car owners.
To use SZ Viewer A1, you will need an ELM327 adapter with Bluetooth or Wi-Fi connectivity, specifically version 1.3 or later. Beware of counterfeit adapters, such as those labeled as v2.1 or certain v1.5 versions, as they do not support the necessary ELM327 commands required for this application.
It's important to note that the SDL protocol, used in Suzuki vehicles from before the 2000 model year (utilizing 5V levels on pin #9 of the OBDII connector), is not supported due to physical incompatibility with the ELM327 adapter.
With SZ Viewer A1, you can access and clear DTC errors from a wide array of control modules, including but not limited to: powertrain, engine, AT/CVT, ABS/ESP, SRS, AC/HVAC, BCM, PS, EMCD/4WD/AHL, and TPMS. However, the availability of these modules can vary depending on the specific vehicle being tested.
An important consideration when diagnosing HVAC modules is that codes B1504 or B150A may appear due to insufficient illumination of the sunload sensor during diagnostics. This does not necessarily indicate a malfunction of the sunload sensor itself.
