OBD2 FAULT/CODE READER

Post by Top Croc »

Would like the help of anyone with an OBD2 fault reader.

Battery went U/s in my car and now with new battery car is in "Restricted performance" mode. If anyone could assist it could save me a bundle.

I hope it is a case of re-setting but could be wrong.

Vehicle is a Jaguar.

PM if able to assist.

Thanks in advance TC

Hmm, don't like your chances too much. Even if you find one apart from at the agents, the software is proprietary and may not be of much use for your particular car.

You could try K. Pichai at "L Garage" opposite the Palace just before the traffic lights going north. I think he may have something, but what cars it is for I have no idea. He speaks good English and is obliging.

If you intend to keep the car it may be worthwhile buying your own. But again, the problem is the car specific software and interpretation of fault codes.

The following shop advertises them and I have dealt with them for other items previously.

I bought one last month. You are welcome to borrow it to see if it works on your car.

Thanks Nereus will try K Pichai on return HH.

Generally the reader is either specific to a particular brand/model or more expensive and open to most modern vehicles.

Yes worth while to buy if the car is a keeper, right now need to know is it a "Reset" is all or is it a coil pak etc etc.

Thanks mate, TC

Did you think to check the output of the new battery to make sure it's not faulty? Or some electrical wiring has been disturbed? Is it a problem on starting or after driving for some time?

Hi. There is usually a workaround when it comes to reading engine codes. I'm just assuming here that the 'restricted performance' message is similar to a 'check engine' message (or icon) on some cars, and that it does not actually throttle back to performance (unless in limp-home mode)?
As an aside, these codes are typically generated for an 'emissions' fault - i.e. something that could affect the way your car would contribute to global warming et al. That is what OBD II was designed to do. It is not a fault-finding cure-all, so this needs to be taken into consideration. Note, also, that each manufacturer have their own interpretation of these codes, so a generic OBD II reader may not be able to point you in the right direction.

Having said that, with both the Saab and the Nissan, I've found ways to read the internal fault codes (called flash codes). These are specific to the car, having been generated as such, and would probably be of more use. Most forums will have some advice on how to do this, and thus avoid the stealership fees, or at least to give you an idea of what you're going to be in for.

The Saab was easy, you just turned on the ignition but didn't start the car. The code sequence would then flash the 'check engine' light and you'd read the codes depending on the number of flashes.
The Nissan was a bit more contrived and this info was only in the service manual. You won't find it in the user manual and the techs typically don't tell you it is an option. Though they will nod their heads and smile, thinking, 'the b#gg*r found it'..

Troll around the Jag forums, I'm sure other people have had similar problems, and that there is a workaround out there somewhere.

Also good luck with the reader. Do note that you can't use it to reset the codes as it is only a reader, but I'm sure there are postings for that too.

I’m in full agreement with VincentD and his useful post. Regarding resetting the codes, I have a Sealey OBD/II code reader (~$100) that will read and decode fault codes, telling me broadly where and sometimes why they occured. It will also offer to reset the fault codes but that does little more than turn the check engine light off. It doesn’t solve the underlying problem and the check engine light will probably come on again.

I have a more detailed coding set-up for one car that will interrogate numerous ECUs that govern lighting options, auto-locking, SatNav and the like. However, it only allows me to select from preprogrammed options already built-in to the system and not recode anything. For that, it’s the dealer-only software which, if you can get hold of it, is prohibitively expensive.

Good luck!

I have colleagues who play around with this stuff and they use a WiFi OBD2 reader combined with unofficial manufacturers software downloaded onto a laptop. Apparently you can find software for most cars available on the net.

On my XK8 the 'restricted performance' message meant that the air intake duct was split and needed replacing. I'd be in the outside lane going for the kickdown and suddenly the car would act like two cylinders had given up. Dangerous when you've got a Landcruiser screaming up your rear (wasn't in Thailand). Letting the car change down again to fourth would bring the performance back to normal, but I think the warning stayed on until the engine was stopped restarted. So it can mean many things. Let's us know what your problem is when you've run the diag. :)
