[furrymancha]

Hi, can anyone help me.
Ive converted to st170 discs on the rear & replaced the abs pump(second hand) & replaced all sensors for new & the abs & tc lights stay on 13mph test works can hear it & all sensors have been metered & read the same 1.1 & all wired have been metered & read the same??? Help please

Did you change the tone rings when you fitted the focus hubs? If not then the Puma sensors have nothing to read.

I am sorry, but could you describe what is exactly the problem? If I understood correctly, the ABS goes and passes the self testing procedure? Is the light on or off?

My money would be on one of the rear sensors not set up correctly.
The system can be very fussy about the strength of the signal.
I had a similar problem on the FRP, finished up checking the outputs from the sensors with an oscilloscope.One of them was weak. I had to fiddle about with the gap till I got it right.
