While I was routing the new Flex Fuel Wiring, I raised the right side up, disconnected the battery, and ran the white #40 wire. In order to remove the fuel line, I had to move the ABS module connector -- which meant I had to dis-connect it from the EBCM. Looks like that opened up another can of worms!

I had to move the connector. Once I got everything back together and did a test start -- the StabiliTrak came on WITH the ABS light.

Normally, that would be a spark plug wire loose, but not in this case. Since the coil connector was damaged, I went ahead and replace it on the passenger's side (driver's on it way). I also fixed my tune for VVT delete (more on that later). I had to know 'what' the issue was with the ABS, so, I had this little gem:

BlueDriver. This is an OBDII Bluetooth sender that works with the BlueDriver software -- and why did I get it? It will read ABS DTCs! Yep, I have a Tech2, but this will work with my IPad -- and I love that. So, I installed their software on the IPad, hooked up my BlueDriver Bluetooth adapter, and bingo, ABS Code!

The Code was C0050 -- Right Rear Passengers sensor! Well, I happened to have a 'rear' sensor when I thought I broke it the last time, so, I had to remove it any way (this sensor was like $12). I had to jack up the rear, remove the right rear tire, get to the 'sensor' connector, then unbolt it:

Sensor:

Installed:

Took all of 15 minutes -- I know, but since I had to do the work anyway, just eliminate it. I can tell you that 90% of the time, its the sensors but, not for me (2010 model years had a 'body rub' area and that is more common on that year model -- thus, look for a 'cut' wire first)...

So, put it back together, cleared the abs code (with my new best friend), and started it up -- yep, you guessed it, same code.

So, NOW, I need to trace a broken/grounded feed wire -- thank goodness I have the service manuals.

The connector on the EBCM is K17:

I need to check a white wire (31) and brown wire (19):

When I removed the K17 connector, I did notice where some 'heat' melted the outer shell protector -- that is where I'll start -- its the 'last' thing I removed and installed -- and I'm betting, that is where I'll find it.

Break time -- I'll dig into that next...
