range.
(AT vehicle only) (No terminal is provided in the MT vehicle.)
@
GY Clutch switch MT vehicle:
This terminal is usually grounded, and is disconnected from ground when the clutch
pedal is depressed.
AT vehicle:
It is always grounded.
@
Br Main switch
If the main switch is turned on with the ignition-starter switch on, the battery volt-
age is transmitted. The voltage is cut off when it is turned off.
® YR
Speed sensor
When the speedometer cable rotates with the ignition-starter switch on, on-off
signals at more then 5V and OV are repeatedly transmitted.
® B
Ground
This is always grounded. (grounding wire of the control unit)
(j)
G Vacuum valve The signal for operating the vacuum valve is input.
®
YB
Resume switch
If the resume switch is turned with the ignition-starter switch on, the battery volt-
age is transmitted. The voltage is cut off if it is returned.
® BR
Brake switch With the ignition-starter switch on, the battery voltage
is
transmitted. When the
brake pedal is depressed, the voltage becomes OV.
® Y Ignition coil It transmits ignition pulse signals while the engine is running.
@
WB Valve (common) While the cruise control is operating, the battery voltage is transmitted from the
control unit to each valve.
@
YW
Check This is the check terminal used for quality inspection in the production line.
[The cruise control can be temporarily canceled by entering a pulse signal cor-
J
responding to the engine speed of 5,500 rpm or more.
@
LW Vent valve The signal for operating the vent valve is transmitted.

W
Set switch If the set button is pressed with the ignition-starter switch on, the battery voltage is
transmitted. The voltage becomes OV if it is returned.
@
L Coasting switch
If the coasting switch is turned with the ignition-starter switch on, the battery volt-
age is transmitted. The voltage is cut off if the switch is returned.
@
GB
Stop switch When the brake pedal is depressed, the battery voltage is transmitted. The voltage is
cut off when it is released.
NOTE:
a. Of the above terminals, the signal from
(j),
@ ,and
@
are not transmitted unless the cruise control unit is actually operat-
ed with the unit connected to the electric wire.
b. Check each of the terminals according to the troubleshooting chart
