    Default On Board Diagnostic scanner OBD2

    I am looking at purchasing an OBD2 scanner. Suitable for a VX commodore but not restricted to. I know very little about them and want to know which one to get and where is the best place to get one from.

    What are the advantages and diadvantages of them and why such a big variation in price between them?

    Any advice would be good? Thanks
    Cheers Tinman

    ok from a trade point of view you can only really get a multi use platform that has diff connectors and programmes for the diff cars. the diff in price is A what they can do/diagnose and B the cars that it covers. we have a snap on one at work and it cost aobut 5K. Im not sure but i dont think you can buy one only for a certain car ( well not one that gives you enough info to be any use)

    You can buy USB ones off ebay, i have not had any experiance with them, but was tempted to to get an OBD-1 one for the VS.

    It is the ones on ebay I have been looking at. Obviously they are just a basic code scanner but how limited are they and what will they tell. Price is anywhere from $35- upwards. I know they are not going to be anything like a industry type scanner that could program and actually test the sensors ect.

    It would be handy and could save a few dollars putting the car in to the service technician. A while ago the wife tells me the light is on on the dash. I have a look. Car is running ok nothing obvious. Take it down to the local technician/mechanic. $80 later he tells me it was a wire fallen of the knock sensor. Not impressed.

    JA5ONS - VR/VS are OBD2, VN/VP are OBD1

    Tinman - basic code scanners will only give you the fault code, you will need the workshop manual to find out what that translates to. Also, aftermarket scanners are limited to what they can do depending on the OEM as some functions are deemed security, ie changing the km's on the dash

    Hold up there, I'm not sure at all about VR/VS being OBD II compliant, I have a strong feeling they aren't. I know for a fact that 5 litre cars with the exception of VT HSV and VT police cars are *NOT* OBD II compliant and full compliance with all models only came in with the VT series 2.

    A lot of those codes are DTC codes which are Holden specific which is why the Tech 2 (or Tech 1) was / is required.

    Jaycar now sells a hand held OBD II scanner that will report fault codes and clear them.

    Personally though, I can't really see the point as I can generally tell whats going / gone wrong with a listen or a drive BUT as I don't have an auto trans I don't need to worry about any faults related to an auto.

    They can't report faults like "broken cluster gear in gearbox" or "spun bearing".

    They can report faults like "injector no 8 not pulsing" or "no fuel rail pressure" etc.

    They can be helpful for sorting out ECU problems BUT all Holdens prior to the VE (not sure about the VE) can give fault codes by bridging pins 5 and 6 on the OBD connector.

    Read this for a bit of technical info and why VR / VS cars don't comply:

    EDIT: Before any one says anything, when I said all Holdens prior to VE I meant VN through to VZ ;-)

    yeah those usb ones were what i was reffering to (well not one that gives you enough info to be any use) all they do is give you a code, you need to look it up. the biggest pitfall is that the codes only point you in the right direction. THEY NEVER TELL YOU WHAT IS ACTUALLY WRONG ie a code comes up for mass air flow reading out of range, it isnt the air flow meter thats buggered its a tps switch or in the case of the astras its the crank angle sensor playing games. Its just that because of the crank angle sensor playing up the air flow sensor gives a bung reading which is out side the paramaters the computer has in its memory. Soooooooo the point of all that is like i said just to point you in the right direction.

    Tinman I can understand hoiw you wouldnt be impressed however that is the price to pay for some one who is a mechanic and has spent 5 k on a scanner. just think for a plumber ot come out to your house and tell you that you have a blocked sewer pipe and that he cant do it is $80. Honestly for shit we go through and do some times mechanics is the worst paid trade

    Right, the VR/VS and non HSV VT 5 litre do have an OBD II style connector but it isn't used with OBD II devices as it isn't compliant.

    EDIT: Just to clarify that a bit more - the Holdens use ALDL protocol for data comms. All of them prior to VT HSV. Thats why a tech 2 can be used on a VT or VN or VS all with different connectors. Post VT HSV are OBD II compliant.

    The fault code are all listed in my Gregory's manual. So that is not a problem. I currently have a VX which I think is OBD2 and it has the 16 pin plug.

    From what I have read on these cheap units they dont read the transmision codes. I asume these are some of the Holden specific codes.

    When you break a gear cluster it is pretty easy to work out the problems in the gear box. Pulling down an engine or gearbox is not a problem. Been doing that since I was 10 years old on the farm.
    In the last 2 year I have had problems with a whole heap of sensors. Cam angle sensor replaced, crank angle sensor relaced, O2 sensors replaced, a wire fell off one of the knock sensors. The light comes on on the dash. You turn the car off and back on agian it goes out but usualy idles like a pig and has a big flat spot when you take off. To change the sensore is an easy job but which one? And another code went in two days ago. WTF is it now? Back to the mechanic. It is the first car I have had with the electronic control module and the experience has not been the best one.
    If one of these cheap units can tell me that kind of thing I would be over the moon.

    Well, if a wire has fallen off a knock sensor, the unit isn't going to give you a fault for "Wire fallen off knock sensor", it'll give you some other fault.

    If I get a fault code (last one was "Low Speed Fan Fault" and was totally unrelated to the fan) then I treat it as if it were wrong and recheck everything anyway.

    They encourage lazy fault finding and I am convinced they are resposible for the latest breed of lazy mechanics and service centres who assume the problem is only what the reader tells them and nothing else.

    A bit of common sense is required when using one of these. Just don't take them as a life saver.

    Question OBD II Diagnostic

    I'm after a obd II diagnostic tool (Tech 2) for a VY 2002 SV8 Commadore. Searched Jaycar web site as one of you guys suggested, but could not find it. Part no would be good. I have fault codes tough for SDM 6.2 & 8.0-8.1. Can send these if requested. Got it from manaul for VT-VX-VY manual. Assume this is only for Tech 2 only. My issue is with my SRS, but would like to know other stuff how my car is running just like all of you. Just needs reseting I think. Found something on eBay but they cannot re-assure my that it will work.
