Check ECU Powering Up
Each engine has a power distribution block (PDB) on
the main engine harness that provides power to the ECU
through the ECU control relay; main relay; and fuses in
Positions 1, 2, 3, 4 and 8. (Figure 5-45)
To check the ECU powering up:
1. Locate the PDB on the right side of the paver inside
the engine access door.
2. Fuses can be checked by removing the fuse and
using a continuity tester OR checking for +12VDC on
each pin on the back of the fuse.
3. Conrm operation of ECU and main relays:
• If the ECU relay is not energizing, starter will not
operate.
• If the main relay is not energizing, the fuel pump
will not operate.
If none of these procedures correct the problem,
contact your authorized LeeBoy dealer for assistance.
