Fault Description:
When voltage is present on AVIONICS BATT DIRECT BUS while DC Power Center (DCPC) Solid State Power Controller (SSPC) 4 is off and there is voltage on the SSPC 4 output, the continuous monitoring test will fail. This will indicate SSPC 4 or Diode (D4) short circuit fault.
Possible Causes:
- Solid State Power Controller (SSPC) 4
- Avionics Battery Remote-Control Circuit Breaker (AV BATT RCCB) (CCBP CB-D1)
- Diode (D4)
- DC Power Center (DCPC) Primary Logic Card (PLC) 1
- DC Power Center (DCPC) Primary Logic Card (PLC) 2
- DC Power Center (DCPC) Primary Logic Card (PLC) 3
- DC Power Center (DCPC) (A63)
- Associated Wiring

Troubleshooting Recommendations:
- Make sure the AV BATT RCCB is not tripped (OUT).
- Use CAIMS to access active faults. Is message 2460449DCP DCPC DIODE #4 (D4) FAILED posted?
- If YES, troubleshoot this message first.
- If NO, continue with next step.
- Disconnect SSPC 4 (K10) connector P403. Remove all three Primary Logic Cards (PLC 1, PLC 2 and PLC 3) from the DCPC. Perform a continuity check of the AV BATT RCCB as follows:
From To Result P403-11 Ground - If there is no continuity, investigate the AV BATT RCCB.
- If there is continuity, continue with next step.
- Perform a continuity check of SSPC 4 Coil status, Coil command, load status and gate status as follows:
From To Result P403-3 Ground P403-4 Ground P403-12 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 P403-3 P110A-10 P403-3 P210A-10 P403-3 P310A-10 P403-4 P110B-26 P403-4 P210B-26 P403-4 P310B-26 P403-12 P110B-25 P403-12 P210B-25 P403-12 P310B-25 - If there is no continuity, replace DCPC and do close out.
- If there is continuity, continue with next step.
- Replace SSPC 4 (K10). Is the fault resolved?
- If YES, do close out.
- If NO, continue with next step.
- Perform SmartFix Plus task for fault code 2460449DCP.
- Do close out.
