8. Inspection of Park/Neutral Position Switch Circuit, A/T

DESCRIPTION OF OPERATION

When the gear selector lever is placed in the "N" position during vehicle speed control, a cancel signal is input to the control unit which internally interrupts the power supply to the vacuum pump assembly drive circuit for cancellation of vehicle speed.
