BF MkIII I6 intermittent speedo issue

Post by VX L67 Getrag »

I have a customer with a 2008 BF MkIII 6 cylinder 4 speed auto s/wagon & it has an intermittent speedo cutting out & then obviously going into limp home mode.

From BF onwards Ford went from transmission transducer to wheel speed sensor to ABS module to BEM & then to dash.

So I checked fault codes & they all could be related or they could just be multiple issue's they were;
P0622-Generator Field "F" (which in GM is the connector on alternator & can cause voltage spikes & LOT's of electrical issues)
P1502-Lost wheel speed sensor (obvious, but which 1 & why)
U1900-ABS Can Comm Bus Fault (without it communicating can't get signal to BEM or then dash)
U2514-Missing Message for vehicle speed (internal or wiring issue?)

So has anyone had similar issues & know a common fault or is it just a mixed bag of lollies?
