| DTC P0563: | ECM/PCM Power Source Circuit Unexpected Voltage |
| 1. | Turn the ignition switch ON (II). |
| 2. | Do the DTC CLEAR in the CLEAR MENU with the Honda PGM Tester or the HDS. |
| 3. | Turn the ignition switch OFF. |
| 4. | Wait 10 seconds. |
| 5. | Turn the ignition switch ON (II). |
| 6. | Check for Temporary DTCs or DTCs in the DTCs MENU with the Honda PGM Tester or the HDS. Is DTC P0563 indicated? YES - Go to 7. NO - Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the No. 8 FI-ECU (ECM/PCM) (15A) fuse in the under-hood fuse/relay box and at the ECM/PCM.n |
| 7. | Turn the ignition switch OFF. |
| 8. | Jump the SCS line with the Honda PGM Tester or the HDS. |
| 9. | Disconnect ECM/PCM connector E (31P). |
| 10. | Measure voltage between ECM/PCM connector terminal E7 and body ground. Is there battery voltage? YES - Go to 13. NO - Go to 11. |
| 11. | Remove the kick panel, then remove PGM-FI main relay 1 (FI MAIN) (A) from the under-dash fuse/relay box. |
| 12. | Check for continuity between ECM/PCM connector terminal E7 and body ground. Is there continuity? YES - Repair short in the wire between the ECM/PCM (E7) and PGM-FI main relay 1 (FI MAIN), then go to 20. NO - Go to 19. |
| 13. | Reconnect ECM/PCM connector E (31P). |
| 14. | Measure voltage between ECM/PCM connector terminal E7 and body ground. Is there battery voltage? YES - Go to 15. NO - Go to 26. |
| 15. | Disconnect ECM/PCM connector A (31P). |
| 16. | Measure voltage between body ground and ECM/PCM connector terminals A3 and A2 individually. Is there battery voltage? YES - Go to 17. NO - Go to 26. |
| 17. | Remove the kick panel, then remove the PGM-FI main relay 1 (FI MAIN) (A) from the under-dash fuse/relay box. |
| 18. | Measure voltage between body ground and ECM/PCM connector terminals A3 and A2 individually. Is there battery voltage? YES - Repair short to power in the wire between the ECM/PCM (A2, A3) and the PGM-FI main relay 1 (FI MAIN), then Go to 20. NO - Go to 19. |
| 19. | Replace the PGM-FI main relay 1 (FI MAIN) (A). |
| 20. | Turn the ignition switch ON (II). |
| 21. | Do the DTC CLEAR in the CLEAR MENU with the Honda PGM Tester or the HDS. |
| 22. | Turn the ignition switch OFF. |
| 23. | Wait 10 seconds. |
| 24. | Do the ECM/PCM idle learn procedure . |
| 25. | Check for Temporary DTCs or DTCs in the DTCs MENU with the Honda PGM Tester or the HDS. Are any Temporary DTCs or DTCs indicated? YES - If DTC P0563 is indicated, check for poor connections or loose terminals at the PGM-FI main relay 1 (FI MAIN) and the ECM/PCM, then go to 1. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC troubleshooting. NO - Troubleshooting is complete. n |
| 26. | Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM. |
| 27. | Check for Temporary DTCs or DTCs in the DTCs MENU with the Honda PGM Tester or the HDS. Are any Temporary DTCs or DTCs indicated? YES - If DTC P0563 is indicated, check for poor connections or loose terminals at the PGM-FI main relay 1 (FI MAIN) and the ECM/PCM, then go to 1. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC troubleshooting. NO - If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, replace the original ECM/PCM.n |
