Something I learned from rereading the service manual is the procedure to get into the engineering test mode of the IPC. This mode doesn't offer too much, but you can test the analog speedometer, check for burnt out lights on the instrument panel, and even see real time speed. To enter the mode, with the car off, hold in the left OK button on the steering wheel. Start the car and hold the button in until you see a yellow ET on the top left of the left screen. After this, okay the "Read to Drive" screen and you can scroll up and down to see the various tests. Not too useful, but interesting none the less. To exit the mode, hold in the OK button again or restart the car. Enjoy!
