YES -Go to step 27.

NO -Replace PGM-FI main relay 1 (FI MAIN), then go to step 20.

20. Reconnect all connectors.

21. Turn the ignition switch ON (II).

22. Reset the ECM/PCM with the HDS.

23. Do the ECM/PCM idle learn procedure (see ECM/PCM IDLE LEARN PROCEDURE ).

24. Turn the ignition switch OFF.

25. Wait 10 seconds.

26. Check for Temporary DTCs or DTCs with the HDS.

Is DTC P0563 indicated?

YES -Check for poor connections or loose terminals at PGM-FI main relay 1 (FI MAIN) and the
ECM/PCM, then go to step 1.

NO -Troubleshooting is complete. If any other Temporary DTCs or DTCs are indicated, go to the

27. Reconnect all connectors.

28. Update the ECM/PCM if it does not have the latest software (see UPDATING THE ECM/PCM ), or

substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ).

29. Check for Temporary DTCs or DTCs with the HDS.

Is DTC P0563 indicated?

YES -Check for poor connections or loose terminals at PGM-FI main relay 1 (FI MAIN) and the
ECM/PCM. If the ECM/PCM was updated, substitute a known-good ECM/PCM (see SUBSTITUTING
THE ECM/PCM ), then recheck. If the ECM/PCM was substituted, go to step 1.

NO -If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted,
replace the original ECM/PCM (see ECM/PCM REPLACEMENT ). If any other Temporary DTCs or
DTCs are indicated, go to the INDICATED DTCS TROUBLESHOOTING.

DTC P0602: ECM/PCM PROGRAMMING ERROR

1. Do the ECM/PCM update procedure (see UPDATING THE ECM/PCM ).

2. Check for Temporary DTCs or DTCs with the HDS.

Is DTC P0602 indicated?

YES -Replace the original ECM/PCM (see ECM/PCM REPLACEMENT ).

NO -Updating is complete. If any other Temporary DTCs or DTCs are indicated, go to the INDICATED
DTCS TROUBLESHOOTING.

DTC P0603: ECM/PCM INTERNAL CONTROL MODULE KEEP ALIVE MEMORY (KAM) ERROR

1. Turn the ignition switch ON (II).

2. Clear the DTC with the HDS.

3. Check for Temporary DTCs or DTCs with the HDS.

NOTE:



Before you troubleshoot, record all freeze data and any on-board
snapshot, and review the general troubleshooting information (see
GENERAL TROUBLESHOOTING INFORMATION ).



This DTC is indicated when the ECM/PCM update is not completed.



Do not turn the ignition switch OFF while updating the ECM/PCM. If you
turn the ignition switch OFF before completion, the ECM/PCM can be
damaged.

NOTE:

Before you troubleshoot, record all freeze data and any on-board snapshot, and
review the general troubleshooting information (see GENERAL
TROUBLESHOOTING INFORMATION ).
