    Hi everyone - first post (whoop)
    so I've been trying to trace an intermittent fault with ASC (light comes during long motorway journeys) and I want to pull the fault codes to find out what's gone wrong...

    I'm using INPA\EDIABAS v6.4.3 over a modified VAG-COM KKL cable which happily chats away to the ecu, the central locking module, the climate control and lets me play with all the motors from the laptop (grin) but crucially I can't get it to talk to the ABS module :(

    Anybody got theirs spitting out the error codes?
    Know which ABS module I should have (INPA lists about 6 different modules and trial and error doesn't get me anywhere)?
    Something obvious I'm missing (should the engine be running, does the ABS module have a separate diag port?)
    Different software like carsoft or GT1?

    Any advice is bound to help! Thanks

    I "think" the ABS is on a different K line.
    It should work if your mods to the cable is bridging the k-lines.

    Sounds about right I think it's only the Instrument Cluster you won't be able to access.

    If it helps I can read the ABS on my 1996 E36 M3 using a modified Vagcom lead.

    Thanks for the help guys,
    I'll check my cable mod against some pinouts, I thought I'd done this already by bridging pin 7&8 on the 16-pin OBD-II connector, but I was following a guide written for E46's rather than doing it the hard way and checking the proper pin-outs.

    I'll keep you posted on progress when I get home from work!

    dammit - still no good :(
    I've checked all my cables and no luck.

    My car's 20-pin plug has the following pins populated:
    1 (Engine Speed)
    2 (OBD Diagnostic - whats this?) *EDIT 12 (Charge Lamp)*
    7 (Service reset)
    14 (Bat +12v)
    15 (L Line)
    16 (??????)
    18 (??????)
    19 (GND)
    20 (K Line)

    and the diag. cap has 4 pins that seem to bridge 15&14 and 18&19 when covering the port.

    So I guess I don't have that second K line.

    Perhaps it's software that's causing the hassle - I'm running INPA v.4.4.7 (yet title bar claims it's UK version 3.01)and EDIABAS v.6.4.3 which talk to all other modules happily - unless the engine's running when it'll go FUBAR after a second or 2. It's classing my E36 as an old model (very insulting ;P) so do I need an older version of INPA or different software altogether?

    Again - thanks for the advice guys

    I'm a bit rusty on this but I'm starting to wonder if comms with your ABS module requires the L line which will not be available via OBD. If that's the case you may need an ADS interface. I've checked backed through my emails from when I was playing around with this and I've got one from a E36/7 Z3 owner who couldn't access their IC or the ABS so it maybe the same for you.

    I'm running Inpa version 5.02 but have used 4.4.7 in the past.

    pin 16 is called 15S, which is ignition on
    pin 18 is the programming line, aka PGSP
