Aldl interface
Tech2 and SDT use this propritary/OBD1 interface. The official, and hugely expensive, factory scan tools, the Tech1, The primary interface on Suzuki ECUs is a proprietary format (generally still referred to as OBD1) and where an OBD2 or EOBD interface is alsoįitted, to meet legislative requirement, it is limited to the legal minimum.

Of course manufacturers were free to adopt OBD2 or EOBDīefore the mandated dates so legislation dates only mean that vehicles introduced after those dates will meet the relevant specification,īefore those dates they may be OBD2, EOBD or proprietary. Japan adopted EOBD in 2004, AustraliaĪdopted EOBD in 2006 and India is currently scheduled to adopt it in 2013. In the US OBD2 was mandated from 1996 onwards, in Europe legislation required the adoption of EOBD (mostly compatible with OBD2)įrom 2001 for new petrol engined passenger vehicles through to 2004 for existing models of diesel engined passenger vehicles. The terms 'OBD1' and 'OBD2' are actually very specific to the US but have achieved common usage worldwide. The majority of Suzuki ECUs from 1991 onwards were fitted withĪ diagnostic link, a notable exception being the Swift GTi models.

Most manufacturers did fit diagnostic interfaces and these were usually proprietary. Prior to the adoption of OBD2 some countries had a mandatory requirement for On Board Diagnostics, others didn't.
