About SZ Viewer: read DTC for Suzuki

1. Developed for Suzuki vehicles SZ Viewer A1 uses specific protocols (via K-Line and CAN bus) along with standard OBDII ones.

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

3. 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.

4. This application can read and reset DTC codes (including extended and historical codes) of many Suzuki control modules.

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

6. 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.

7. An HVAC module may display B1504 or B150A DTC due to insufficient illumination of a sunload sensor during a diagnostic procedure.

8. However, not all modules may be present on a tested vehicle.

9. This is not a symptom of a sunload sensor malfunction.

2. Using on sx4 awd j20aWorks fine with european Vitara 2015 (LY), shows a lot of stuff on engine, AT, HVAC, SRS, e.t.c. The only thing lacking - is the ability to see graphs on O2 sensors data, or m.b. some kind of autotest-analysis for their data flow.

3. I tried all other OBD2 apps trying to find error codes for my Suzuki Alto 2009, but none of them worked for me.

4. This SZ Viewer A1 was able to determine the error and reset some other errors which makes me happy .. It would be wonderful if it can save log data.

8. Even though connecting is sometimes need a few reignition, after connected the data is shown in real time.

9. As some others mentioned, it's already amazing as it is considering it's free with no ad but GUI / graphs would be a great add-on.

10. Does work on 24$ veepeak Shows everything you need to see to avoid seeing a dealer:) simple, intuitive.

11. I used it for a 2011 Suzuki Alto HA25 with Automatic transmission.
