Fault Message:
DCPC SSPC1-K7 FAILED
Fault Code:
2460428DCP
Associated CAS:
| Reporting LRU: | DC Power Center (DCPC) |
| System Description: | 24-60-00 |
| Schematic Diagram: | 24-61-00 [ Global Express ] [ G5000 ] [ Global XRS ] |
| Wiring Diagram: | 24-61-01 [ Global Express ] [ G5000 ] [ Global XRS ] |
Fault Description:
When voltage is present on DC Bus 1 while DC Power Center (DCPC) Solid-State Power Controller (SSPC) 1 is off and there is voltage on the SSPC 1 output, the continuous monitoring test will fail. This will indicate SSPC 1 or Diode (D1) short circuit fault.
Possible Causes:
- Solid-State Power Controller (SSPC) 1
- Diode (D1)
- DC Power Center (DCPC) (A63)
- Primary Logic Card (PLC) 1
- Primary Logic Card (PLC) 2
- Primary Logic Card (PLC) 3
- Associated Wiring

Troubleshooting Recommendations:
- Get access to CAIMS active faults. Is message 2460446DCP DCPC DIODE 1 (D1) FAILED posted?
- If YES, troubleshoot this message first.
- If NO, continue with next step.
- Disconnect SSPC1 (K7) connector P103. Remove all three Primary Logic Cards (PLC 1, PLC 2 and PLC 3) from the DCPC. Perform a continuity check of SSPC 1 Coil status, Coil command, load status and gate status as follows:
From To Result P103-3 Ground P103-4 Ground P103-6 Ground P103-12 Ground - If there is continuity, replace DCPC and do close out.
- If there is no continuity, continue with next step.
- Perform a continuity check as follows:
From To Result P103-3 P110A-7 P103-3 P210A-7 P103-3 P310A-7 P103-4 P110B-18 P103-4 P210B-18 P103-4 P310B-18 P103-6 P110A-13 P103-6 P210A-13 P103-6 P310A-13 P103-12 P110B-17 P103-12 P210B-17 P103-12 P310B-17 - If there is no continuity, replace DCPC and do close out.
- If there is continuity, continue with next step.
- Replace SSPC 1 (K7). Is the fault resolved?
- If YES, do close out.
- If NO, continue with next step.
- Perform SmartFix Plus task for fault code 2460446DCP.
- Do close out.
