11. Inspection of Circuit Associated W/ Overdrive Cancel A/T
No.11 Inspection of Circuit Associated w/ Overdrive Cancel A/T
DESCRIPTION OF OPERATION
On a vehicle with cruise control, the OD switch ON signal is input through the cruise control unit to the ELC-A/T control unit.
When the vehicle speed control is in the overdrive mode, if the actual vehicle speed falls more than about 7 km/h (4 mph) below the set vehicle speed or the RESUME switch is turned ON, the cruise control unit forces transistor Tr1 into the OFF state. This cancels the overdrive mode because no OD switch ON signal is input to the ELC-4A/T control unit.
