How to Reset the MCM

How to Reset the MCM
You can reset the Motor Control Module (MCM) using either this method or How to End a Troubleshooting Session.

* 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 (7.5 A) 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.
