14. Measure the voltage between ECM/PCM connector

terminal A8 and body ground.

Repair short to power in the wire between

the ECM/PCM (A8) and PGM-FI main relay 1, then
go to step 16.

Go to step 15.

15. Test PGM-FI main relay 1 (see page 22-70).

Go to step 23.

Replace PGM-FI main relay 1, then go to step

16.

16. Reconnect all connectors.

17. Turn the ignition switch to ON (II).

18. Reset the ECM/PCM with the HDS.

19. Do the ECM/PCM idle learn procedure (see page

11-310).

20. Turn the ignition switch to LOCK (0).

21. Wait 10 seconds.

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

Check for poor connections or loose

terminals at PGM-FI main relay 1 and the ECM/PCM,
then go to step 1.

Troubleshooting is complete. If any other

Temporary DTCs or DTCs are indicated, go to the
indicated DTC’s troubleshooting.

23. Reconnect all connectors.

24. Update the ECM/PCM if it does not have the latest

software (see page 11-227), or substitute a known-
good ECM/PCM (see page 11-7).

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

Check for poor connections or loose

terminals at PGM-FI main relay 1 and the ECM/PCM.
If the ECM/PCM was updated, substitute a known-
good ECM/PCM (see page 11-7), then recheck. If the
ECM/PCM was substituted, go to step 1.

If the ECM/PCM was updated, troubleshooting

is complete. If the ECM/PCM was substituted,
replace the original ECM/PCM (see page 11-228). If
any other Temporary DTCs or DTCs are indicated,
go to the indicated DTC’s troubleshooting.

NOTE:

• Before you troubleshoot, record all freeze data and

any on-board snapshot, and review the general
troubleshooting information (see page 11-3).

• This DTC is indicated when a ECM/PCM update is not

completed.

• Do not turn the ignition switch to LOCK (0) or ACC (I)

while updating the ECM/PCM. If you do, the ECM/
PCM can be damaged.

1. Do the ECM/PCM update procedure (see page

11-227).

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

Replace the original ECM/PCM (see page

11-228).

The update is complete. If any other

Temporary DTCs or DTCs are indicated, go to the
indicated DTC’s troubleshooting.

NOTE:

• Before you troubleshoot, record all freeze data and

any on-board snapshot, and review the general
troubleshooting information (see page 11-3).

• Information marked with an asterisk ( ) applies to

the ’06-08 models.

• Information marked with a double asterisk (

)

applies to the ’09 model.

1. Turn the ignition switch to ON (II).

2. Clear the DTC with the HDS.

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

Go to step 4.

Intermittent failure, the system is OK at this

time.

4. Update the ECM/PCM if it does not have the latest

software (see page 11-227), or substitute a known-
good ECM/PCM (see page 11-7).

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

If the ECM/PCM was updated, substitute a

known-good ECM/PCM (see page 11-7), then
recheck. If the ECM/PCM was substituted, go to
step 1.

If the ECM/PCM was updated, troubleshooting

is complete. If the ECM/PCM was substituted,
replace the original ECM/PCM (see page 11-228). If
any other Temporary DTCs or DTCs are indicated,
go to the indicated DTC’s troubleshooting.
