Breakout box pin numbers and ABS ECU terminal numbers are identical. 1. Turn ignition switch to RUN position. Check for battery voltage between breakout box pins No. 1 and 3, and pins No. 1 and 33. If no voltage is present at either pin No. 3 or 33, check ABS 30-amp fuse in main bulkhead fuse box. Also check Red wire from fuse to main relay and distribution block on battery tray. 2. If wiring is okay but voltage is still not present, ensure continuity is present between breakout box pin No. 3 and relay terminal No. 30 (White wire), and between breakout box pin No. 33 and relay terminal No. 87a (Black wire). Ensure 10-amp ABS fuse is okay. download
