SZ Viewer: read DTC for Suzuki A1-2023-11-01

Developed for Suzuki vehicles, SZ Viewer A1 utilizes specific protocols (via K-Line and CAN bus) in addition to standard OBDII ones. This application is capable of reading and resetting DTC codes, including extended and historical codes, from numerous Suzuki control modules.

• Japanese domestic market (JDM) Suzuki cars are also supported, even if they do not inherently support OBDII protocols.
• An ELM327 adapter (Bluetooth or Wi-Fi) version 1.3 or newer is necessary. Imitation ELM327 adapters (such as those labeled v2.1 or some v1.5) are unsuitable as they lack support for essential ELM327 commands.
• The older SDL protocol (pre-2000 model year, with 5V levels on pin #9 of the OBDII connector) is not compatible due to physical constraints with ELM327.

This application enables users to access and reset DTC errors across various control modules, such as powertrain, engine, AT/CVT, ABS/ESP, SRS, AC/HVAC, BCM, PS, EMCD/4WD/AHL, TPMS, and more. Notably, it's important to bear in mind that not all modules may be present in every tested vehicle.

An HVAC module may exhibit B1504 or B150A DTC codes as a result of insufficient sunload sensor illumination during diagnostic procedures. It's crucial to note that this doesn't signify a fault with the sunload sensor itself.
