CRUISE CONTROL – CRUISE CONTROL SYSTEMCC–5
CC
SYSTEM DESCRIPTION
1. CRUISE CONTROL SYSTEM
This system is controlled by the ECM, and is activated by
the throttle position sensor and motor. The ECM controls
the following functions: ON-OFF, SET / COAST,
RESUME / ACCEL, CANCEL, vehicle speed operation,
motor output control, and overdrive control.
• The ECM compares the driving vehicle speed from
the combination meter with the stored vehicle speed
set through the cruise control switch. The ECM
controls the throttle valve motor of the throttle body to
open the valve when the driving speed is less than the
stored speed.
• The ECM receives signals such as ON-OFF, SET /
COAST, RESUME / ACCEL, and CANCEL from the
cruise control switch.
• The ECM illuminates the combination meter CRUISE
main indicator light when it receives the cruise control
switch ON signal.
• The ECM cancels the cruise control system when the
brake pedal is depressed and the ECM receives the
stop light switch signal.
• The ECM cancels the cruise control system when the
shift lever is moved from D or 3 to a position other
than D or 3, and the ECM receives the PNP switch
signal.
2. LIMIT CONTROL
(a) Low speed limit
The lowest possible limit of the speed setting range
is set at approximately 40 km/h (25 mph). The
cruise control system cannot be set when the
driving vehicle speed is below the low speed limit.
Cruise control operation will be automatically
canceled when the vehicle speed decreases below
the low speed limit 40 km/h (25 mph) while the
cruise control is in operation.
(b) High speed limit
The highest possible limit of the speed setting range
is set at approximately 200 km/h (125 mph). The
cruise control system cannot be set when the
driving vehicle speed is over the high speed limit.
Also, +/RES cannot be used to increase speed
beyond the high speed limit.

INSPECTION
1. INSPECT MULTIPLE DISC CLUTCH HUB
(a) Using a caliper gauge, measure the inside diameter
of the forward clutch hub bushing.
Standard inside diameter:
23.03 to 23.05 mm (0.9067 to 0.9075 in.)
Maximum inside diameter:
23.09 mm (0.9091 in.)
NOTICE:
Check the contact surface of the bushing in the
direct clutch shaft. If any scratch or
discoloration is found, replace the direct clutch
sub-assembly with a new one.
If the inside diameter is greater than the maximum,
replace the forward clutch hub with a new one.
2. INSPECT NO. 2 UNDERDRIVE CLUTCH DISC
(a) Check if the sliding surfaces of the disc, plate and
flange are worn or burnt.
If necessary, replace them.
NOTICE:
• If the lining of the disc comes off or is
discolored, or if a part of the groove is worn,
replace all the discs.
• Before installing new discs, immerse them in
ATF for at least 15 minutes.
3. INSPECT OVERDRIVE DIRECT CLUTCH DRUM SUB-
ASSEMBLY
