    Various volvo models with Jetronic fuel injection, had up until 1996 a
    diagnostic unit which could display a flash code for what the ECU's self
    diagnostic system had recorded.
    Does anyone know what exactly is inside the diagnostic unit.
    The connections to the unit includes a positive lead, a ground and the
    diagnostic leads to the Jetronic ECU and the Ignition ECU.
    The unit has a pushbutton and a LED for displaying the codes.
    But what is the function inside this unit?


    Remove "spamstopper" from adress if direct email is used.
