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
Control - Terminal 11 The output circuit is switched to 12 V to enable the component(s).
Control - Terminal 24, 25 The output circuit is switched to ground to activate the component.
The output is PWM controlled.
Component Description
K71 Transmission Control Module The control module contains a microprocessor used to process input data to control outputs.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.
Q77 Transmission Control Solenoid Valve A linear solenoid actuator is an electro-mechanical device that converts electrical power into a mechanical pushing or pulling force or motion.
  • The solenoid actuator varies the force depending on the current applied to the solenoid coil.
  • The solenoid actuator applies minimum force with minimum current applied to the solenoid coil.
  • The solenoid actuator applies maximum force with maximum current applied to the solenoid coil.
