    OBDII cables and software Overwhelmed and baffled

    Freely admitted, I don't live and breath this stuff. I've been getting by with an older hand-held scanner for years. But I'd really like to go ahead and get into something good with a laptop PC. And that's where I get baffled.

    ELM 323, ELM 327, TRICOM, TRICAM, MobyDick. There are probably a few others. Darned if I can really understand the differences to know how to select. Google searching gives everything but a clear understanding of the differences and advantages of one over the other. And yes, I've been searching this forum as well. If there's a generic 101 post, I've not found it.

    Then there's the software, that's just about as confusing. Alex Pepers stuff, Digimoto, OBDPROs, etc. I just can't figure out who's does what, especially with regards to advanced features, particularly manufacturers codes. Alex Pepers is expensive and appears to maybe have manufacturers specific codes, but as cryptic as his web page is, god only knows if I would understand his software. OBDPRO is on this board a lot and has lots of recommendations for his hand holding. That counts for a lot. But is it just generic OBD-II codes?

    I want/need to do a multitude of vehicles. Mine and friends vehicles, as well the changing cars in the future. From the 97 Toyoto to the 06 GM, and anything else in between.

    If you guys can point me to a good clear web page explaining the differences, or some words of your own, I'd sure appreciate it. Because I find myself overwhelmed and confused. So I keep on hiding behind my old hand-held scanner.

    I'd also love to be able to do the various manufacturers tests via the OBD-II port. But that may be too much. Darned if I'm plunking several grand down on the Toyota scanner for example, just to test run my fuel pump. But if someones cable/software whatever let me do that for just a few hundred dollars, I'd be most interested.

    Hi foxtracker,

    If you would like to visit any of the following websites, I think you would learn a lot about OBDII.

    Try in no particular order

    http://www.glmsoftware.com
    http://www.obdpros.com
    http://www.scantool.net
    http://www.obdkey.com

    I'm sure others could add to this list.

    Most of the ELM style interfaces including the OBDPro are capable of perform manufacturers tests provided the supporting software knows the request format, unfortunately most of the Software out there will only handle generic OBD II data.

    Some scantools like the autotap will offer oem specific data via their prorietary software at additional cost. So yes if you are interested in the OEM specific data your choise is probably limited to Autotap & Autoengenuity type scantools but for generic OBD II data the choice is wide open

    Thanks

    SteadVex,

    Our software OBD 2007 works with all European OBDII vehicles. Europe went OBDII in 2000 for petrol vehicles and 2004 for diesel vehicles.

    Steadvex, what software do you want?
    Only engines and gearboxes? Then you can use any OBD2/EOBD scanner on a PC or handheld but expect problems.
    The European Union decided that not all vehicles had to be compliant in the same year. They started with petrol cars. Then a few years later they started with the diesels. However, the last diesels were only to be compliant on 1st january 2007 (Yeah, that's right, last year).
    Here's a quote from the EC document:

    8.1.1. Petrol fuelled engines
    With effect from 1 January 2000 for new types and from 1 January 2001 for all types, vehicles of category M1 - except vehicles the maximum mass of which exceeds 2500 kg - and vehicles of category N1 class I, must be fitted with an OBD system for emission control in accordance with Annex XI.

    With effect from 1 January 2001 for new types and from 1 January 2002 for all types, vehicles of category N1 classes II and III and vehicles of category M1, the maximum mass of which exceeds 2500 kg, must be fitted with an OBD system for emission control in accordance with Annex XI.

    8.1.2. LPG and natural gas fuelled vehicles
    With effect from 1 January 2003 for new types and from 1 January 2004 for all types, vehicles of category M1 - except vehicles the maximum mass of which exceeds 2500 kg - and vehicles of category N1 class I, running permanently or part-time on either LPG or natural gas fuel, must be fitted with an OBD system for emission control in accordance with Annex XI.

    With effect from 1 January 2006 for new types and from 1 January 2007 for all types, vehicles of category N1 classes II and III and vehicles of category M1, the maximum mass of which exceeds 2500 kg, running permanently or part-time on either LPG or natural gas fuel, must be fitted with an OBD system for emission control in accordance with Annex XI.".

    8.2. Vehicles with compression-ignition engines
    Vehicles of category M1, except
    - vehicles designed to carry more than six occupants including the driver,
    - vehicles whose maximum mass exceeds 2500 kg,

    from 1 January 2003 for new types and from 1 January 2004 for all types, must be fitted with an on-board diagnostic (OBD) system for emission control in accordance with Annex XI.

    Where new types of compression-ignition engined vehicles entering into service prior to this date are fitted with an OBD system, the provisions of sections 6.5.3 to 6.5.3.6 of Annex XI, Appendix 1, are applicable.

    8.3. Vehicles with compression-ignition engines exempt from Section 8.2

    From 1 January 2005 for new types and from 1 January 2006 for all types, vehicles of category M1 exempted by Section 8.2, except vehicles of category M1 equipped with compression-ignition engines and the maximum mass of which exceeds 2500 kg, and vehicles in category N1 class 1 equipped with compression-ignition engines, must be fitted with on-board diagnostic (OBD) systems for emission control in accordance with Annex XI.

    From 1 January 2006 for new types and 1 January 2007 for all types, vehicles in category N1, classes II and III equipped with compression-ignition engines and vehicles of category M1 equipped with compression-ignition engines and the maximum mass of which exceeds 2500 kg, must be fitted with on-board diagnostic (OBD) systems for emission control in accordance with Annex XI.

    The full documents can be found here:
    http://eur-lex.europa.eu/LexUriServ/...9L0102:EN:HTML
    http://eur-lex.europa.eu/LexUriServ/...1L0001:EN:HTML

    Now if you want to do more than just engines, you need some manufacturer specific software or scanner.
    Excellent PC-software is available for VW/Audi from Rosstech an for Opel there's the program OP-COM (or VAUX-COM in the UK).
    There's software for other makes too, but the opions on th quality of these vary greatly.
