VXDIAG VCX NANO and Forscan Test on Sport Trac Mountaineer
Haven’t been able to get any past v86 to work when installed on a laptop running XP.
I tried installing v81 then v91 then v97 but that didn’t work, not even for 3 days. Nor did changing the time, date and time zone.
I was able to set the tire size and some other things, including reading DTCs that require communication with the PCM.
But when attempting to program the latest calibration to the PCM or do the ABS Service Bleed, there’s suddenly a “PCM Communication Failure”. It also fails to do the KOEO and KOER tests, claiming it cannot sense when the brake pedal is depressed.
All bogus, false errors. I get the same “communications failure” on a completely stock 1998 Mountaineer as I do on my 2002 Sport Trac with 1998 Mountaineer drivetrain.
FORscan scan tool can do the KOEO and KOER tests and the ABS module self test with this VCX NANO device, but it does not yet support the ABS bleed function. FORscan can also clear KAM from the PCM, which IDS v86 fails to do with the VXDIAG VCX NANO, again that “communications failure” with the PCM. FORscan can also do the other tests that involve running the windows, wipers, locks and windshield washer.
Would be interesting to be able to borrow a VCMII to see if it has the same “failure”.
Something in the system is still falsely setting a VSS error when there for damn sure is not. If there was, the speedometer would not work, nor would anything else dependent on the single speed sensor in the rear axle.
Since it reads the Mountaineer PCM, it won’t let me do anything with the rear window that doesn’t work. ELS27 FORscan also picks up on that and won’t let me have access to rear window control in the Sport Trac GEM.
