Go to step 22.
Repair open in the wire between the ECM/
PCM (C22) and the rocker arm oil pressure switch,
then go to step 16.
15. Turn the ignition switch to LOCK (0).
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. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals at the rocker arm oil pressure switch, the
rocker arm oil control solenoid, and the ECM/PCM,
then go to step 1.
Go to step 21.
21. Monitor the OBD STATUS for DTC P2647 in the DTCs MENU with the HDS.
Troubleshooting is complete. If any other
Temporary DTCs or DTCs were indicated in step 20,
go to the indicated DTC’s troubleshooting.
If the screen indicates FAILED, check for poor
connections or loose terminals at the rocker arm oil
pressure switch, the rocker arm oil control solenoid,
and the ECM/PCM, then go to step 1. If the screen
indicates NOT COMPLETED, keep idling until a
result comes on.
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. Start the engine, and let it idle.
