Hello All! Yes, this is yet another ABS problem question. I have read countless threads on ABS issues but cannot seem to pinpoint a solution to my issue. First a quick rundown on my rig:
1994 - 178K
3" OME lift
MAF Control Arm and sway arm drop brackets
35" BFG Muds
all else pretty stock
I did the lift about a year ago and had no real braking issues. Once I added the tires (2 months ago), I noticed the brakes were a bit "weaker" so I flushed the entire system, new dot 4, bled a million times, adjusted the LSPV valve and bled some more. Pedal feels fine, master and booster are good, all calipers and pads are good, parking brake is good - but ABS light on. ABS will not engage with panic braking and while its disabled the brakes are good but not great - guessing 80% (with ABS disabled if I jump on the brakes it will not lock) Pulled codes with paper clip and got RL senson, FR sensor, and the dreaded code 36 (either FR or RL open circuit) - changed the speed sensors out and cleared those codes. However, still have code 36. I traced the harnesses all the way and saw no visible damage and any connections along the way were opened and all clean. How can I pinpoint where the open circuit is? Dont want to buy full new harnesses from the stealership - there must be a way to trace the wiring to either the FR or RL in increments (between connections) and test integrity....... and once I find it (fingers crossed) can this be spliced? any thoughs would be most appreciated. Thanks!
