SZ Viewer: read DTC for Suzuki

For Suzuki vehicle enthusiasts looking to diagnose and manage Diagnostic Trouble Codes (DTCs), the SZ Viewer A1 application is an indispensable tool. Designed specifically for Suzuki vehicles, SZ Viewer A1 utilizes both Suzuki-specific protocols via the K-Line and CAN bus, as well as standard OBDII protocols. This powerful application allows users to read and reset a wide range of DTC codes, including extended and historical codes, across various Suzuki control modules.

Not limited to international models, SZ Viewer A1 also supports Japanese Domestic Market (JDM) Suzuki cars, even those that do not adhere to OBDII standards. This makes it a versatile tool for a broad spectrum of Suzuki vehicle owners.

To leverage the capabilities of SZ Viewer A1, an ELM327 adapter with Bluetooth or Wi-Fi connectivity, version 1.3 or later, is required. It's crucial to avoid counterfeit adapters labeled as v2.1 or certain v1.5 versions, as they lack the necessary support for the required ELM327 commands, which could hinder the diagnostic process.

It's important to note that SZ Viewer A1 does not support the older SDL protocol used in pre-2000 model year Suzuki vehicles due to physical incompatibilities with the ELM327 adapter.

With SZ Viewer A1, you can efficiently manage DTC errors across a variety of control modules, including powertrain, engine, AT/CVT, ABS/ESP, SRS, AC/HVAC, BCM, PS, EMCD/4WD/AHL, and TPMS. Keep in mind that not every vehicle will have all these modules.

When diagnosing an HVAC module, you might encounter DTCs B1504 or B150A, which can occur due to insufficient illumination of the sunload sensor during the diagnostic procedure. This does not necessarily indicate a malfunction of the sunload sensor itself.
