How to Substitute the MCM

How to Substitute the MCM
1. Remove the MCM.
2. Install a known-good MCM.
3. Do the MOTOR ROTOR POSITION CALIBRATION.

NOTE: If the IMA battery level gauge (BAT) displays no segments, 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.
