I did have a bad earth on my ABS pump, which brought up another error message - can't remember what that was now, but fixed that - wonder where else it could be, as I have been through and changed all the earth straps etc when I fitted a second battery and addiditional fuse box - interesting tho.....
 
Maybe force an error to be logged and see if you can read it. If you can't then you know there is a dodgy earth for the ecu or dodgy ecu its self.
 
Only problem with doing that, is then I cannot reset it without a visit to my local Indi to get it hooked up which costs......
