Circuit/System Description
| Circuit | Description |
|---|---|
| Control - Terminal 11 | The output circuit is switched to 12 V to enable the component(s). |
| Control - Terminal 12 | The output circuit is switched to ground to activate the component. |
| Component | Description |
|---|---|
| K71 Transmission Control Module | The control module contains a microprocessor used to process input data to control outputs.The control module receives information from a variety of sensors, switches and serial data information from other control modules. This information is used to control a combination of solenoid valves to obtain the correct line pressure, gear ratio and torque converter clutch operation. |
| M123 Transmission Park Valve Lock Solenoid Actuator | A linear solenoid actuator is an electro-mechanical device that converts electrical power into a mechanical pushing or pulling force or motion. |
When the component is commanded on, the park servo valve is held in the out of park position, preventing the transmission from going into park.
