Anyone know what to check when I get 3 warning lights pop on when (usually) turning right at speed.

The abs light, the TC light and the ! light, they pop on for 10 secs then go out.

Had it scanned and it came up with voltage low or voltage signal low or implausable/intermittant something, left the printout behind, duh

I would check the wires for the abs/tc and brake pads warning lights that go from the body to the front wheels, possibly a damaged wire making and breaking as you turn the wheel.

I'd check the brake fluid, upon turning the fluid is surging away from the low fluid sensor. It could be due to a leak or worn brake linings.

just had new front pads and fluid today, lights have been intermittent for a few weeks

You need the codes really - as that will tell you where to look. My hunch given that it is only when you turn is one of the ABS sensor looms has an intermittent break, down in the wheel well.
