    Where to start?

    Hi there I am very interested in connecting my ECU or ECM system to my carpc but at a loss to where to start.

    I have a 1999 Mitsubishi Colt Rodeo 4X4 double cab pickup

    My first question is whether I have OBDII on this car. Most of my reading (yes I have done some reading) suggests that my car does have OBDII. My first problem is trying to find the port (ie the plug) where one would connect a harness/cable to.

    I also have a piggyback computer called Unichip

    This has a open plug which I suspect is used to "program" the Unichip.

    Once I have found the OBDII port my next challenge would be to find the cable and software that would allow me to monitor the engine/car parameters.

    Where do I start to look for specs on my particular car's ECU? The local guys are very unhelpful/clueless about how this is done.

    Any pointers would be appreciated

    first, open the bonnet, there should be a plate with the engine info, it should say OBD-II on there if it is.

    as for the port, it will be close to the driver, look down by the pedals, behind the ashtray, undre the dash, places like that.

    Have found OBD port. Engine plate gives no indication of OBD type. According to digimoto I have a Type A J1962 connector that uses the ISO standard.

    Where to now?

    Should I buy a cable/package from someone like Digimoto and try it out?

    With all these cables/harnesses and software solutions around - which one should I try first?

    I bought an ISO interface from but cannot get it to work properly (BUS INIT ERROR). Can anybody suggest how I can get it to work?

    Have you tried the Scantool support site? There's a troubleshooter there.

    Very frustrated

    After much research and emails I am now quite certain that my car is OBD2 compliant using ISO as the protocol but I still cannot get my scantool to communicate with my ECU (BUS INIT....ERROR) . All the right lights flash and the tool is working (tried it on another car).

    I do have a Unichip fitted and was wondering whether this piggyback chip is causing the problem?

    Scantool have offered to refund me but I am still keen to try and get it to work. Any help would be appreciated
