Hey guys,


1st post here!!!


Been having ABS problems, Codes C0226, C0265, and C0227


Replaced the front left bearing today and now I'm only down to 1 code!!!


C0265


I have the Kelsey Hayes 310, and from what I read it is not prone to circuit board corrosion failure as other EBCMs


I believe I may have a ground issue. I used the ModuleMasters "Kelsey Hayes 310 ground diagnostic" sheet (Kelsey-Hayes 310 ABS Module | ModuleMaster) and get the following readings:


Step 1: 0.3 ohms
Step 2: 0.9 ohms
Step 3: 0.5 ohms


My main question is where is the ground located on my frame for the EBCM for my 98 Blazer?


Thanks for the help guys!!!

 

At the EBCM connector 1, pin J, is a black with white stripe wire. It runs through the underhood fuse panel, then goes to the rear of the right cylinder head, (along with a few other grounds).
Pin B is a black wire and runs to the left radiator support.
