Hi, still have the ABS problem, I found how to pull ABS codes in my truck but when I try no codes are displaied.
Instructions said "If grounding this wire does not start the REAR ABS lamp flashing, go to System Pre-Check Test D, Yellow REAR ABS Light Self-check OK, but no diagnostic trouble code when diagnostics are started."
My question is: Where can I find System Pre-Check Test D?
