    Default Reading DTC from other than PCM in VX Commodore

    I have a V8 VX Commodore and I'm trying to diagnose an ABS/Traction Control problem. I've tried to read the DTC from these modules but EFILive Flashscan seems only to be able to read DTCs from the PCM.

    I have read in old posts that this is due to the PIM interface that Holden use and that the feature will be added to EFILive Flashscan.

    Has this feature been added yet? If not, is there any other tool that I can use to read these DTCs?

    The ABS, BCM, Inst Cluster etc are all on the ALDL bus which is different to the PCM. The purpose of the PIM in the Holden is to translate the messages from the ALDL bus to the PCM's data bus.
    Our V4 software and hardware will talk on the ALDL bus (but not to the LS1 PCM).......or wait for V2 as it will do both bus types.
