hi all.
Warning light on the dash came on, fault code read which pointed at nsf abs speed sensor fault. the wiring to the sensor was checked and found to be split/open circuit and possibly touching each other.
This was repaired, rechecked, same code back again.Wheel sensor also replaced. Dash cleared and no codes returning.
On test drive however the abs kicks in under low low braking at all speeds.
A speed signal is received from all wheels in vcds and a scope of the pattern looks good from each wheel.
Abs pump/ ecu time?
thanks.
