SZ Viewer

Developed for Suzuki vehicles SZ Viewer A1 uses specific protocols (via K-Line and CAN bus) along with standard OBDII ones. This application can read and reset DTC codes (including extended and historical codes) of many Suzuki 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 for use as they do not support the required ELM327 commands.

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

This application allows you 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. However, not all modules may be present on a tested vehicle.

An HVAC module may display B1504 or B150A DTC due to insufficient illumination of a sunload sensor during a diagnostic procedure. This is not a symptom of a sunload sensor malfunction.
