- Turn the ignition switch ON (II).
- Clear the DTC with the HDS.
- Turn the ignition switch OFF.
- Wait 10 seconds.
- Turn the ignition switch ON (II).
- Check for Temporary DTCs or DTCs with the HDS. Is DTC P0563 indicated? YES- Go to step 7 . NO- Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the No. 6 FI ECU (15 A) fuse in the under-hood fuse/relay box, PGM-FI main relay 1 (FI MAIN), and the ECM/PCM.
- Turn the ignition switch OFF.
- Jump the SCS line with the HDS.
- Disconnect ECM/PCM connector E (31P).
- Measure voltage between ECM/PCM connector terminal E7 and body ground. Is there battery voltage? YES- Go to step 13 . NO- Go to step 11 .
- Remove the glove box (see «GLOVE BOX REMOVAL/INSTALLATION»(ref-220597-S26723889242006022100000) ), then remove PGM-FI main relay 1 (FI MAIN) (A).
- 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 step 20 . NO- Go to step 19 .
- Reconnect ECM/PCM connector E (31P).
- Measure voltage between ECM/PCM connector terminal E7 and body ground. Is there battery voltage? YES- Go to step 15 . NO- Go to step 26 .
- Disconnect ECM/PCM connector A (31P).
- Measure voltage between body ground and ECM/PCM connector terminals A3 and A2 individually. Is there battery voltage? YES- Go to step 17 . NO- Go to step 27 .
- Remove the glove box (see «GLOVE BOX REMOVAL/INSTALLATION»(ref-220597-S26723889242006022100000) ), then remove PGM-FI main relay 1 (FI MAIN) (A).
- 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 PGM-FI main relay 1 (FI MAIN), then go to step 20 . NO- Go to step 19 .
- Replace PGM-FI main relay 1 (FI MAIN) (A).
- Reconnect all connectors.
- Turn the ignition switch ON (II).
- Clear the DTC with the HDS.
- Turn the ignition switch OFF.
- Wait 10 seconds.
- Do the ECM/PCM idle learn procedure (see «ECM/PCM IDLE LEARN PROCEDURE»(ref-220572-S08440202922006022000000) ).
- Check for Temporary DTCs or DTCs with the HDS. Are any Temporary DTCs or DTCs indicated? YES- If DTC P0563 is indicated, check for poor connections or loose terminals at PGM-FI main relay 1 (FI MAIN) and the ECM/PCM, then go to step 1 . If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting. NO- Troubleshooting is complete.
- Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM (see «ECM/PCM UPDATING AND SUBSTITUTION FOR TESTING»(ref-220569-S23624043112006022000000) ).
- Check for Temporary DTCs or DTCs with the HDS. Are any Temporary DTCs or DTCs indicated? YES- If DTC P0563 is indicated, check for poor connections or loose terminals at PGM-FI main relay 1 (FI MAIN) and the ECM/PCM, then go to step 1 . If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting. NO- If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, replace the original ECM/PCM (see «MAP SENSOR REPLACEMENT»(ref-220570-S17955277902006022000000) ).
