Circuit/System Description
WARNING: This page is about a different car, the 2022 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.
For an overview of the component/system, refer to: Exhaust Tail Pipe Flow Control System Description and Operation
| Circuit | Description |
|---|---|
| Ignition | Supplied from a fuse. |
| Signal | The control module input circuit has a high impedance and can float high or low when the circuit is open. The sensor produces a PWM signal. |
| Control | The output circuit is switched to ground to activate the component. The output is PWM controlled. |
| Ground | Chassis Ground |
| Component | Description |
|---|---|
| M106 Exhaust Control Valve Actuator | The exhaust flow control valve is actuated by a DC motor. The control valve is spring loaded to the open position. The motor overcomes the spring pressure to close the control valve. An increase in current flow through the motor increases the closing of the control valve. |
| K111 Fuel Pump Power Control Module | The control module contains a microprocessor used to process input data to control outputs. The control module communicates with the engine control module via serial data. |
