The speed output is not being transmitted form the wheel to the ECU,

We've changed

Hi,

is this an ABS single wheel speed issue or a problem with the instrument speedo readout? On the early cars the cluster gets the speed signal from the gearbox sensor rather than a feed from the ABS unit.

If it is a wheel sensor, have you verified the full circuit back from the wheel sensor connector to the ABS controller connector?

ABS pins:

Right rear 6 and 7
Left rear 36 and 37
Right front 3 and 4
Left front 33 and 34
