Suzuki protocols

Old 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:

• Pin #9: SDL protocol. This is an old-style 5V level protocol related with GM ALDL. Also modern Suzuki vehicles may use this pin to link with an immobilizer. These protocols are not supported by SZ Viewer.
• Pin #7: Suzuki K-Line (fast or 5Baud init) protocol. This protocol is supported by SZ Viewer. But sometimes K-Line is used for non-Suzuki protocols (early ISO 9141, for example) and pin #9 is present. In this case SZ Viewer is unable to connect to all or some modules.
• Pins #6 and #14: Suzuki CAN/CAN-UDS protocols. These protocols are supported by SZ Viewer (excepting some of the newest modules).

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.

Plain OBD II protocols are not supported by SZ Viewer. There are many other apps compatible with OBD II.
