SZ Viewer: read DTC for Suzuki

If you're looking to diagnose and troubleshoot issues with your Suzuki vehicle, the SZ Viewer A1 application is your go-to tool. Designed specifically for Suzuki cars, this app leverages both standard OBDII protocols and specialized protocols via K-Line and CAN bus to interact with various control modules. With SZ Viewer A1, you can effortlessly read and reset Diagnostic Trouble Codes (DTCs), including extended and historical codes, ensuring a comprehensive diagnostic experience.

One of the standout features of SZ Viewer A1 is its support for Japanese Domestic Market (JDM) Suzuki vehicles, which may not adhere to OBDII standards. This makes it an invaluable tool for Suzuki enthusiasts and mechanics alike, regardless of the vehicle's origin.

To use SZ Viewer A1, you'll need an ELM327 adapter with Bluetooth or Wi-Fi connectivity, specifically version 1.3 or later. Be cautious, as counterfeit adapters labeled as v2.1 or some v1.5 versions do not support the necessary ELM327 commands and are unsuitable for this application. Additionally, note that the older SDL protocol used in pre-2000 model year Suzuki vehicles (5V levels, pin #9 of the OBDII connector) is not compatible with ELM327 adapters due to physical differences.

SZ Viewer A1 enables you to access and reset DTC errors across a wide range of Suzuki control modules, including powertrain, engine, AT/CVT, ABS/ESP, SRS, AC/HVAC, BCM, PS, EMCD/4WD/AHL, and TPMS. Keep in mind that not all modules may be available on every Suzuki model you test.

When diagnosing HVAC modules, you might encounter DTCs like B1504 or B150A, which can be triggered by insufficient illumination of the sunload sensor during the diagnostic process. It's important to understand that these codes do not necessarily indicate a malfunction of the sunload sensor itself.
