So the motor swap is finally done. Took for a drive and it works like it should as far as hybrid mode goes. 4cyl mode 8cyl.. all that... BUT my traction light brake light and abs light are all on... the brake peddle has zero power boost. The brakes do work but not very well. I ran my mdi and can't find a reason why any of those lights are on.... when trying to reset or reprogram the EBCM it freezes disconnects and says failed.... thoughts?

 

What codes are you reading?

 

used my mdi2 and actually got the codes here ya go.

code last test this test since last clear
c0201 mil req current + history
c12ff failed/current failed mil requested failed
b1543 --- ---- --------
c0396 passed passed passed and failed
c0392 passed passed passed and failed
c0561 mil requested current + history
b1289


ive un done most of the3 harness looking for a pinched/ shorted wire.. but not sure where i should look

 

Most of those are related to the electronic brake control module (EBCM), and the transfer case control module, so check the harness to those. B1543, based on a Google search, may be an oil pressure sensor circuit issue.

 

okay I did actually see a broken wire on a sensor that goes to the oil pan. Lower drivers side. I forgot about that until you said something. Repairing now. But my code wasn't for B1543

 

I just had to replace a abs module on a Ford taurus X this week, only 30k mile on a 08 was odd, but while these trucks EBCM is way more complicated, one of the trouble tree tests was to run the abs motor with the scanner. that tested communication to the module itself. mine failed and a 1600$ module fixed it. but was wondering if you can command the EBCM to run the abs pump?

 

Issue solved! Upon relearning the EBCM it was failing due to pressure at master cylinder. Removing the cap and performing the relearn again solved the issue. All abs trac control lights are off now.

 

I would have never guessed. glad you fixed it.
