NOTE: Before you troubleshoot, record all freeze data
and any on-board snapshot with the HDS, and review
General Troubleshooting Information (see page 14-3).
1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Turn the ignition switch to LOCK (0), then turn it to ON (II) again.
4. Check for Temporary DTCs or DTCs in the PGM-FI SYSTEM with the HDS.
Go to the indicated DTC’s troubleshooting in
the PGM-FI system.
 P0107 (see page 11-80)
 P0108 (see page 11-82) Go to step 5.
5. Check for Temporary DTCs or DTCs in the A/T SYSTEM with the HDS.
Go to step 6.
Intermittent failure, the system is OK at this
time. If any other Temporary DTCs or DTCs were
indicated, go to the indicated DTC’s
troubleshooting.
6. Update the PCM if it does not have the latest software (see page 11-227), or substitute a known-
good PCM (see page 11-7).
7. Start the engine, and wait for at least 2 minutes. 8. Check for Temporary DTCs or DTCs in the A/T
SYSTEM with the HDS.
Check for poor connections or loose
terminals at the PCM. If the PCM was updated,
substitute a known-good PCM (see page 11-7), then
go to step 7. If the PCM was substituted, go to step
1.
Go to step 9.
9. Monitor the OBD STATUS for P0107 or P0108 in the DTCs MENU with the HDS.
If the PCM was updated, troubleshooting is
complete. If the PCM was substituted, replace the
original PCM (see page 11-228). If any other
Temporary DTCs or DTCs were indicated in step 8,
go to the indicated DTC’s troubleshooting.
If the HDS indicates FAILED, check for poor
connections or loose terminals at the PCM. If the
PCM was updated, substitute a known-good PCM
(see page 11-7), then go to step 7. If the PCM was
substituted, go to step 1. If the HDS indicates NOT
COMPLETED, go to step 7.
