Unplug the Main MIMA ribbon connector from the MIMA board. Insert the test connector. Start the car idle in neutral, e-brake on.
DVM negative lead on pin 19(MAP GND)

If all test correctly, you can bundle up the ECM harness, and replace the ECM in the car.
Re connect the MIMA controller. The car should start normally, but we may have triggered another code with the disconnected wires, If so follow the reset procedure.
Take the car for a ride. Try pressing the mode 2 button when the car is moving less than 15 MPH. the mode light should flash in, then go right back off. Increase speed to over 25MPH. Tapping the mode 2 (PIMA) switch should light the second mode led, and allow the PIMA to work with the default settings. You should see assist come on when you step down on the gas, and charging when you let up. Jog the settings to your liking. See more on operating MIMA .
