Honda Element. Manual — part 807

22. Monitor the OBD STATUS for DTC P2648 in the DTCs MENU with the HDS.

Does the screen indicate PASSED?

YES -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 were indicated in step 21, go to the indicated DTCs troubleshooting.

NO -If the screen indicates FAILED, check for poor connections or loose terminals at the rocker arm oil
control solenoid and the ECM/PCM. If the ECM/PCM was updated, substitute a known-good ECM/PCM
(see SUBSTITUTING THE ECM/PCM ), then go to step 20. If the ECM/PCM was substituted, go to
step 1. If the screen indicates NOT COMPLETED, go to step 20.

DTC P2649: ROCKER ARM OIL CONTROL SOLENOID CIRCUIT HIGH VOLTAGE

1. Turn the ignition switch ON (II).

2. Clear the DTC with the HDS.

3. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator

fan comes on, then let it idle.

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

Is DTC P2649 indicated?

YES -Go to step 5.

NO -Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at
the rocker arm oil control solenoid and the ECM/PCM.

5. Turn the ignition switch OFF.

6. Disconnect the rocker arm oil control solenoid 2P connector.

7. At the solenoid side, measure resistance between rocker arm oil control solenoid 2P connector terminals

No. 1 and No. 2.

NOTE:

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

Is there 14-30 ohms, at room temperature?

YES -Go to step 8.

NO -Go to step 13.

8. Check for continuity between rocker arm oil control solenoid 2P connector terminal No. 1 and body

ground.

Is there continuity?

YES -Go to step 9.

NO -Repair open in the wire between the rocker arm oil control solenoid and G101, then go to step 14.

9. Jump the SCS line with the HDS.

10. Disconnect ECM/PCM connector B (24P).

11. Connect rocker arm oil control solenoid 2P connector terminal No. 2 to body ground with a jumper wire.

Is there continuity?

YES -Go to step 20.

NO -Repair open in the wire between the ECM/PCM (B6) and the rocker arm oil control solenoid, then
go to step 14.

13. Replace the rocker arm oil control valve (see ROCKER ARM OIL CONTROL VALVE

REMOVAL/INSTALLATION ).

14. Reconnect all connectors.

15. Turn the ignition switch ON (II).

16. Reset the ECM/PCM with the HDS.

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

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

Is DTC P2649 indicated?

YES -Check for poor connections or loose terminals at the rocker arm oil control solenoid and the
ECM/PCM, then go to step 1.

NO -Go to step 19.

19. Monitor the OBD STATUS for DTC P2649 in the DTCs MENU with the HDS.

Does the screen indicate PASSED?

YES -Troubleshooting is complete. If any other Temporary DTCs or DTCs were indicated in step 18, go
to the indicated DTCs troubleshooting.

NO -Check for poor connections or loose terminals at 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.

20. Reconnect all connectors.

21. 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 ).

22. Start the engine, and let it idle.

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

Is DTC P2649 indicated?

YES -Check for poor connections or loose terminals at the rocker arm oil control solenoid and the
ECM/PCM. If the ECM/PCM was updated, substitute a known-good ECM/PCM (see SUBSTITUTING
THE ECM/PCM ), then go to step 22. If the ECM/PCM was substituted, go to step 1.

NO -Go to step 24.

24. Monitor the OBD STATUS for DTC P2649 in the DTCs MENU with the HDS.

Does the screen indicate PASSED?

YES -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 were indicated in step 23, go to the indicated DTCs troubleshooting.

NO -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. If the ECM/PCM was updated,
substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ), then go to step 22. If
the ECM/PCM was substituted, go to step 1. If the screen indicates NOT COMPLETED, keep idling until
a result comes on.
