SZ Viewer: read DTC for Suzuki

Developed for Suzuki vehicles SZ Viewer A1 uses specific protocols (via K-Line and CAN) along with standard OBDII ones. This app can read and reset DTC codes (including extended and historical codes) of many Suzuki's control modules.

Japanese domestic market (JDM) Suzuki cars are also supported even if they do not support OBDII protocols.

An ELM327 adapter (Bluetooth or Wi-Fi) version 1.3 or later is required. Fake (so called v2.1 and some v1.5) ELM327 adapters are not suitable to use because they do not support required ELM327 commands.

Older (before about 2000 model year) protocol SDL (5V levels, pin #9 of OBDII connector) is not supported because of incompatibility with ELM327.

This application allows to view and reset DTC errors for various control modules: powertrain, engine, AT/CVT, ABS/ESP, SRS, AC/HVAC, BCM, PS, EMCD/4WD/AHL, TPMS, etc. But not all modules can be present on a tested vehicle.

A HVAC module may display B1504 or B150A DTC because of insufficient lighting of a sunload sensor during a diagnostic procedure. It is not a symptom of a sunload sensor malfunction.
