Circuit/System Description
WARNING: This page is about a different variant/trim than selected.
For an overview of the component/system, refer to Electronic Component Description
| Circuit | Description |
|---|---|
| 5 V Reference | Regulated voltage supplied by the control module. |
| Signal 1-Terminal 4 @ B15 Transmission Internal Mode Switch | The control module input circuit has an internal resistance connected to 5 V. |
| Signal 2-Terminal 2 @ B15 Transmission Internal Mode Switch | The control module input circuit has an internal resistance connected to 5 V. |
| Low Reference | Grounded through the control module. |
| Component | Description |
|---|---|
| B15 Transmission Range Sensor | The hall-effect sensor has 2 separate PWM signal circuits. The transmission gear selected determines the duty cycle of the PWM signal. |
| K20 Engine Control Module | The control module contains a microprocessor used to process input data to control outputs. 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. |
| 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. |
The control module K71 uses the information from the sensor signal 1 to determine what transmission gear range the vehicle operator selected.
The control module K20 uses the information from the sensor signal 2 to determine if the transmission is in neutral or park to enable the starter.
