Abs Sensor

[darkelfpete]

Hi all, i have just had both front wheel bearings replaced on a Focus 2003 estate, now the ABS Light has just come on. Ive checked and cleaned the wiring connections but still its lit, i've tried to get an OHMS reading but couldn't get any reading. Both Sensors look ok but should i just replace them? if so can i disconnect the battery to reset the fault code or do i have to take it to a garage to clear it?

thanks pete
