Got the back disks and pads done and when I got home the ABS light came on and then it came on then off now it stays on got the work checked again at the garage where the work was done and it looked ok, so was told to take it to honda and was told. No responce from computer so I need a new modulator, £1500. The car is only worth about £2000 and the breaks work just fine, I kow my way about a car and have checked the fuses but are all fine, and the sensors look fine on the wheel so is it a case of changing both and will that fix the problem

hanx!

Hi zzrabzz,

When ABS indicator lights are turned on, the ABS control unit has detected a fault in the system or is faulty. It sounds like you may have a wheel speed sensor that is out. These videos will help us find the problem.

Please run down these guides and report back.

Code retrival is required to check if any trouble codes are present. If a scanner does not show any trouble codes or cannot communicate with the control unit, try a manual code retrieval.

Bridge terminal # 4 and # 9 of the OBD-II data link connector and turn the ignition switch on. Note if the ABS indicator starts blinking a trouble code.

If no trouble codes are present, the control unit could be faulty.
