| Circuit | Description |
|---|---|
| 5 V Reference | Regulated voltage supplied by the control module. |
| Serial Data | Digitally encoded information for communication between devices. |
| Low Reference | Grounded through the control module. |
| Component | Description |
|---|---|
| Q97M Engine Coolant Flow Control Valve - Main | The component is actuated by a bidirectional DC motor.Q97M is part of the component: Q97 Engine Coolant Flow Control Valve |
| K20 Engine Control Module | The control module controls a series of actuators to ensure optimal engine performance. The control module does this by reading values from a variety of sensors, interprets the data and adjusts the engine actuators accordingly. |
To achieve the normal operating temperature faster, an actuator valve can block the coolant flow through the engine block.
