Power Transmission Switch

POWER TRANSMISSION SWITCH







The power transmission switch (circuit) consists of two switches in series. The circuit includes a clutch switch and a gear selector switch on the transmission. The functions of the power transmission switch are as follows:
- Cutout for cruise control operation.
- Enable condition for idle control.

The switches provide a high signal for the MS S52 when the clutch is disengaged and the transmission is in gear.

If either the clutch is engaged or the transmission is in neutral, the cruise control will be disengaged. In addition, this circuit arms the MS S52 to apply torque reduction during hard acceleration and gear changes. This feature is basically accomplished by reducing the throttle openings if the PWG request signal is not reduced during gear changes.
