DTC Troubleshooting (cont’d)
25. Monitor the OBD STATUS for DTC P2647 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 11-205). If any other
Temporary DTCs or DTCs were indicated in step 24,
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 (VTEC oil pressure switch) and the
PCM. If the PCM was updated, substitute a known-
good PCM (see page 11-8), then recheck. If the PCM
was substituted, go to step 1. If the screen indicates
NOT COMPLETED, keep idling until a result comes
on.
Does the scr een indicate PASSED?
