Clearing ABS Faults using Vag-com Golf mk3 gti 16v

Hi i have VAG-COM version 311 full version and the lead (USB to Serial) which works a treat, i was recently able to diagnose a fault with the engine speed sensor with it.

However it also picked up some errors with regards to the ABS system, i am pretty sure they are old codes that need to be cleared, so i want to clear them and run the car for a few days and then plug the lead back in and rescan for codes. My problem is that the codes will not clear using this software, i hit the clear codes button and it does nothing.

Does anyone know how i can get them to clear?

Thanks in advance for you help. Great forum this by the way!

On the older versions, I think you need to log into the particular module and clear the faults from there. The new newer versions allow you to clear all faults from the auto scan screen.

Yeah ive tried doing it from the individual module screen but its still the same, just kinda blinks but does not clear the codes. Same with the clear all DTC's button.

Do you think that i can perform this function on a new version of the software (shareware) with my current lead?

No.

I now think the reason you cannot clear the faults is that they are still there?

What codes are you getting ?

Here ya go:

The reason they will not clear is they are current faults and they won't clear until you fix them. Unfortunately a rear right sensor code normally means a faulty ECU as does the other code. Disconnect the ABS sensors under the back seat and swap the plugs over. Read and clear the codes again and see if the rear sensor fault changes sides, if it does you have a faulty sensor on the right and if it doesn’t clear, the ABS ECU is faulty.

Cool thanks a lot, i will try that! One thing though, if there really was errors wouldnt the dash abs light not be on constantly to disable the system? The abs light on the dash lights up when the ignition turns on for a couple of secs and then goes off.

That is odd but then again, the ECU is probably faulty. Try generating another code by disconnecting the left sensor under the back seat and see if that will clear.

Right done a quick swap over of the sensor leads as suggested and the fault seems to follow the sensor, as you can see its now reporting the left. When i cleared the codes again the error for the right one disappeared.

VAG-COM Version: Release 311.2-N

35-00 - -

If i check / replace the sensor do u think it will clear the other code, would "signal outside specification" be because of a faulty wheel sensor?

Try running the pump in output tests, it still points to a faulty ECU and possibly pump as well, we change a lot of these units.
