The "computer" in your car doesn't have a screen, keyboard or disk drives. But it does have a lot of connections.
Your car's on-board computer doesn't look anything like the kind that's used on a desktop. The "computer" is a small box called an ECU (Electronic Control Unit), often mounted under the seats or in the kick panel. The ECU controls all the essentials of engine operation: spark timing, fuel delivery, emissions, and in some cases even the air conditioning or the automatic transmission. Keeping all these systems in tip-top shape is no simple job; it requires complex test equipment and advanced diagnostic skills.
