help with fault codes

Not quite sure how that would show up on the durametric or how to check them.

In the Actual Values selections (IIRC, in the PSM subsystem) -- I use Durametric version 6. Select the 4 wheels and set recording, then take a very short ride get gather data.


I don't know about the '02 Carrera, but the ABS 4460 code for an '06 Boxster has probable causes of:

Probable Cause[s]
1. Open or short circuit condition
2. Poor electrical connection
3. Low brake fluid condition
4. Faulty sensor

Thanks Paul, I have a durametric pro, but have not had many problems that needed diagnosing, so am not entirely proficient on it, but I will give that a try.

After a lot of testing and reading I think I have it narrowed down to a faulty brake light switch. The switch is definitely not working and I ordered a new one today. It seems that with the tiptronic transmission there is so much interconnectivity with the abs, psm and several other systems that the cause and effect sometimes are not always obvious.
