Handbrake & Abs Lights Have Both Come On - Avensis D4D

[Stompbox]

So there I was this morning, just driving long, stopped at the lights, set off again & HEY - both the handbrake & ABS lights came on. My car is an Avensis T180 D4D 56 reg.

I have one of the ELM 37 computer interface programmes & cable so when I got home, I set it all up, started the car & looked at the faults log - no faults shown!

The lights both resolutely stay on - any ideas?

There is the option of "system reset" on this software - so:-

1) Would that reset the ECU & clear the indicator lights?

2) Is doing a reset a good idea?

Any help most gratefully received on this.

(The handbrake is not on, by the way nor is it jammed or sticking. I haven't tried a really hard brake test to see if the ABS is OK as yet.)

I have just had a nother look - the Traction Contol warning light is on as well.

All th ebrake lights work.
