Bosch ABS 5.3 Invalid ISO Code

[celadon]

I am trying to diagnose a fault with my ABS unit on a 1997 Alfa 155.

However, when I try to connect MES 4.2 to the ABS unit, it returns an error of Invalid ISO

I have scanned the ABS and get the following output :

ABS
UNKNOWN/UNSUPPORTED
ISO CODE : 6B 02 25 08 EF

Any ideas how I can get connected to the ABS.

Try the Fiat Punto I, Seicento, there is 5.3 as well
