Suzuki protocols

Aged Suzuki cars use a 12-pin ALDL-like diagnostic connector. This connector type is not supported by SZ Viewer.

Newer Suzuki cars use a standard (J1962) 16-pin OBDII connector. But applied protocols depend on the connected pins.




Pins #4, #5, #16 should be connected (their wires can be used as reference). To determine protocols check out pins #9, #7, #6 and #14:




There is a little support of non-Suzuki engines (Diesels, or Gasoline GM 3.2 V6, for example) by SZ Viewer now because their modules use non-Suzuki (Renault, Peugeot, GM, FIAT, etc) protocols.

Experimental feature: plain OBD II protocols are supported by SZ Viewer for K-Line or CAN bus.
