ABS,ASC,Tyre pressure light fault codes.

[ccj09]

Hi all just wondering if anyone could shed some light on this for me.
Have been to get the fault codes read by my local garage after all 3 lights (ABS,ASC,Tyre) decided to start been on continuosly, before it was intermittent only came on when it was wet and went off on a nice day all throughout summer they have been fine but right now they wont go off.

My garage used a snap on reader and these were the the codes
SDA1 Speed sensor front right
SDB0 Spped sensor rear left
SE18 can data error from DME/DDC
SDFE System voltage 9 Volts

I understand the first 2 but wonderd are the 2nd two related to just a bad sensor. Garage said these were manufactures codes.
I have replaced the 2 faulty sensors but the lights are still on, will they go out or will i have to take it back to have the codes removed.

Thanks for any help.

All those lights came on my car the other month, it was the abs sensor that needed changing. Cant tell how much it was as the car is under warrenty atm.

I had a similar issue to this before Christmasm but the speedo stopped working as well.

It turned out to be damage to the wiring loom that goes to the ABS/ASC unit in the engine bay. The cable had slipped under the pump support bracket and chaifed through 1 of the wires enough to short it against the bracket and blow a fuse. I managed to thread the cable and plug under the pump and splice in a piece of wire to replace that section. Soldering and shrink wrapping it was a pain.

Because of where the wire sits and that its covered in a fabric wrap that can absorb water it could be the same issue, just different wires?
