MCM Reset

How to Reset the MCM





You can reset the motor control module (MCM) using either of these two methods:
^ Use the HDS to clear the MCM memory. See the HDS user's manual 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 following "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.
^ CVT: Removing the No. 18 fuse may also reset the TCM. Do the start clutch calibration procedure after resetting the TCM.

How to End a Troubleshooting Session
1. Reset the MCM.
2. Turn the ignition switch OFF.
3. Remove the No. 15 EPS (40 A) fuse from the under-hood fuse/relay box.
4. Start the engine, and hold it between 3,500 rpm and 4,000 rpm without load (in Park or neutral) until the BAT displays at least three segments.
5. Reinstall the No. 15 EPS (40 A) fuse.
