How to Reset the MCM

How to Reset the MCM
You can reset the Motor Control Module (MCM) using either of these two methods:
^ Use the Honda PGM tester to clear the MCM's memory. See the Honda PGM Tester user's manuals for specific instructions.





^ Turn the ignition switch OFF, and remove the No. 18 BACK UP (7.5A) fuse (A) from the under-dash fuse/ relay box (B) for 10 seconds.

NOTE:
^ If the MCM has been reset, the IMA battery level indicator (BAT) will not indicate the state of charge when the engine is started. Refer to the "How to End a Troubleshooting Session" to set the correct state of charge.
^ Removing the No. 18 fuse may also reset the ECM. Do the ECM idle learn procedure after reset the ECM.
^ Removing the No. 18 fuse may also reset the TCM. Do the start clutch calibration procedure after reset the TCM.
