While investigating the 50 mph failure of the pcm module, and the ongoing off/on action of the abs module, I ran across what appears to be a mistake on page 43-3 of the fomoco "2001 wiring diagrams/windstar" manual (fcs-12255-01). I exchanged several emails, case # cas-4648613-l1x1r6 crm:03259000003405, with the Ford customer relations center about this matter until they told me to contact a dealer. I sent the questions to my dealer asking for correct information, but they haven't acknowledged my inquiry. What I suspect is all Windstar's on the road today may be operating with only one-half of the scp (j1850 pwm) network operational. Now that many of the defective abs modules are failing, are other Windstars in danger of engine failure at speed like ours? the two simple questions I asked fomoco are: 1) are you sure circuit 915 (data bus-) should be grounded at the abs module? 2) what is the proper termination for the Ford data bus (circuits 914& 915), 120 ohms, 650 ohms, 3k ohms, what and where?.
