This Scantool uses SAEJ1979 (ODB II) protocol on ISO9141, ISO14230, SAEJ1850 VPW and SAEJ1850-PWM interfaces depending on what hardware interface is attached to the PC. The scantool does not yet support any manufacturer specific protocols for talking to non OBDII vehicles.

It is configured by default to use a generic serial to ISO9141 converter such as those used on the VAG-COM software, It also supports smart interfaces from Multiplex Engineering and from B.Roadman for SAEJ1850 vehicles (mainly Ford and GM).

Please refer to the "supported interfaces" document to determine which interface support what protocols.

An open source ODB-II scantool. w00t!

Freediag - Scantool Application Manual

On May 18 2003, officials overseeing an election in Schaerbeek, a suburb of Brussels, got a shock. An electronic vote-counting machine declared that 4,096 more people had cast their vote than the ballot slips testified. The machine had been thoroughly tested and deemed perfect. So what went wrong?

The answer was, literally, a strike from the heavens.

Technicians pointed the finger of blame at cosmic rays -- particles that zip across the cosmos at huge speed and, while rightly ignored by humans as a health concern, can wreak havoc with highly sensitive microelectronic circuits.

Worse engineering excuse *EVER*.

Fried chips: Cosmic rays put new-generation microcircuits to the test
