ASCD INDICATORPFP:24814
Component DescriptionABS007XO
ASCD indicator lamp illuminates to indicate ASCD operation status. Lamp has two indicators, CRUISE and
SET, and is integrated in combination meter.
CRUISE lamp illuminates when MAIN switch on ASCD steering switch is turned ON to indicated that ASCD
system is ready for operation.
SET lamp illuminates when following conditions are met.
CRUISE lamp is illuminated.
SET/COAST switch on ASCD steering switch is turned ON while vehicle speed is within the range of
ASCD setting.
SET lamp remains lit during ASCD control.
Refer to EC-727, "
AUTOMATIC SPEED CONTROL DEVICE (ASCD)" for the ASCD function.
CONSULT-II Reference Value in Data Monitor ModeABS007XP
Specification data are reference value.
MONITOR ITEM CONDITION SPECIFICATION
CRUISE LAMP
Ignition switch: ON MAIN switch: Pressed at the 1st time
→
at the 2nd time ON
→ OFF
SET LAMP
MAIN switch: ON
When vehicle speed is between
40 km/h (25 MPH) and 144 km/h
(89 MPH) ASCD is operating ON
