DTC Troubleshooting (cont’d)
22. Reconnect all connectors.
23. 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).
24. Do the VTC TEST in the INSPECTION MENU with the HDS.
25. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals at the VTC oil control solenoid valve and
the ECM/PCM. If the ECM/PCM was updated,
substitute a known-good ECM/PCM (see page 11-7),
then go to step 24. If the ECM/PCM was substituted,
go to step 1.
Go to step 26.
26. Monitor the OBD STATUS for DTC P0010 in the DTCs MENU with the HDS.
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 were indicated in step 25, go to the indicated
DTC’s troubleshooting.
If the screen indicates FAILED, check for poor
connections or loose terminals at the VTC oil
control solenoid valve and the ECM/PCM. If the
ECM/PCM was updated, substitute a known-good
ECM/PCM (see page 11-7), then go to step 24. If the
ECM/PCM was substituted, go to step 1. If the
screen indicates NOT COMPLETED, go to step 24. NOTE: Before you troubleshoot, record all freeze data
and any on-board snapshot, and review the general
troubleshooting information (see page 11-3).
1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Start the engine.
4. Watch the low oil pressure indicator with the engine running.
Check the engine oil level. If the oil level is
OK, check the oil pressure (see page 8-10), then go
to step 15.
Go to step 5.
5. Do the VTC TEST in the INSPECTION MENU with the HDS.
Go to step 6.
Go to step 9.
6. Test-drive at a steady speed between 40 120 km/h (25 75 mph) for 10 minutes.
7. Check the VTC STATUS in the DATA LIST with the HDS.
Go to step 8.
Go to step 6 and recheck.VTC System Malfunction
