Control Unit (Cu)
The CU monitors and controls all DME system functions. The CU consists of input/output devices, Central Processing Unit (CPU), power supply and memories. The CU is located under the driver's seat.
NOTE:
For ease of understanding, components are grouped into 2 categories. The first category, INPUT DEVICES, is components which control or produce voltage signals that are monitored by the ECU. The second category, OUTPUT SIGNALS, are components that are controlled by the ECU (this is usually accomplished by the ECU grounding individual circuits).
