    Brake, TC and ABS lights.

    This started with the three chimes, then brake system warning light, TC light and the ABS light. No fault logged in the SLABS according to the Nanocom. This was going over Mt Skene on the Labour Day long weekend. It happened twice yesterday and once today. The light, went off on stopping and restarting the engine, except the ABS light, that stayed on until the car moved a few metres. Tonight I had the HDC light, HDC warning light, Brake Light, ABS and TC lights. These did not go off when the engine was stopped and started only went after the car had moved a few metres. Three times in quick succession. No faults in the SLABS according to the Nanocom.
    I'm thinking bad earth some where? Bad connection? But where do I look?

    Earth for the ABS is on passenger side (lhs) of engine bay. For SLABS under dashboard on lhs iirc. Service bulletin regarding earth problem. Look up symptoms and remedies post.
    Push all wires firmly back into abs block (shows as svs switch fault though, if loose).
    Finally, don't do "option b" unless fault indicates that (which it doesn't). Only fixes 2 specific faults (loose abs wire in block and faulty pcb connectors in abs unit).
    If sensor, earth, wiring, SLABS channel, or svs switches etc it just wastes your time. Sure, you may eventually have this problem , which is why people jump to it, but in this case it doesn't match the reported issues (none).

    That's most probably a sensor signal related fault, it won't be the first time for nanocom to miss it, see the live sensor readings maybe you see one different than the others
