ECU and CPU, Where are they located on a 1991 FC3C?
I feel like a dummy asking this question. I need to check them because the engine light is on and the add radiator fluid light is on. The radiator fluid is full and its telling me to add more. The engine light is on but there seems to be nothing wrong. Can someone please help me

ECU: under the carpet on the passenger side. CPU: left of the clutch pedal on the driver side. But finding these probably won't help you with your problems. Pull trouble codes: http://www.johnr.com/cpucodes.html to see what the check engine light is coming on for, then check the coolant level sensor wiring. The sensor is on top of the radiator and just works by grounding when the coolant level is high enough. Air bubbles in the system can also cause the buzzer to go off.
