2006, 6cyl, 9 7x @ 66k miles.
Driven in NYS winters, but annually "Rust Check" pro applied annually.
It isn't too rusty , hood is mint .
I try to do as much searching as possible (I do all my own wrenching) but not seen something like this.
Hoping more tech savy might colabotrate thanks for all you folks do!!!!
Last summer 2014 new (Napa Premium SKF) front hubs w/sensors.
In all cases below -ABS Activation at crawl to stop.
No Dash lights, no codes thrown/stored.
In Jan 2015 RF Wheel sensor no reading - scanned bad, R&R just Sensor in 6 month old/new hub warranty and it fixed it.
Now same, issue so again I got warranty part R&R entire RF Wheel hub & sensor.
But to my surprise still have ABS activation at crawl to stop.
(Spray & cleaned checked that frame to sensor electrical connector).
Made a 15 foot extenstion with 2 extra OEM junkyard ABS Sensor connectors.
Easy to plug & play by just turning wheel and reaching in behind it to connectors.
I moved wheel sensor (via long extention cord electronically) from RF HUB Sensor wheel to LF Frame EBCM input.
(I had - em and I don't have a great VOM I trust to try and solo hold wires and wheel spin test it).
It works and is giving reading.
When I swap and put LF HUB Sensor wheel to RF Frame EBCM input.
It failed to read.... so both wheel sensors are working.
Guess from what I read here to start I might ...
Pull Ground at EBCM and clean for the heck of it.
Pull & clean check all electrical conectors on EBCM for corrosion, electronic cleaner, reinsert and might be fixed?
1) So the EBCM is under Drivers floor board in the slop right?
Can it be unplugged as it sits in place or do you have to pull it off frame?
2) With my extension whip - can anyone tell me which 2 connector pin #'s I might check at the ECBM for continuity?
Or the colors of the 2 lines in (what connector) I might be looking for?
And open to any other suggestions ....
Oh at standstill start up, brake data feed scanner ...
LF, LR and RR all read 2 MPH
The RF trouble one reads 0 MPH
Start rolling out, straight... the LF, LR and RR all read true same MPH as accelearation.
The RF trouble one reads jumps like to 200mph in a split second and then locks at 3.99 MPH
Have no idea if there is a faulty message (3.99?) there like direct short low resistance or ground?
Probably not a "Open" because when you unplug the RF sensor only and leave it off & start car...
You get the ABS and StableTrac lights and live data read like 34mph and its froze.
So I am guessingt it fails a initial start resistance scan then?
Plug it in (even though it wont work proper as noted) and all is back to same action as start of this paragraph.
