3) If meter indicates 12 volts or 0 on specific wire that line
is broken. Normal indication is about 6 volts.
4) For finding out broken position in the line, move positive
lead of voltmeter along the line until abrupt variation in the
meter indication is encountered.
REPAIR
1) Clean broken wire and its surrounding area.
2) Cut off slit on (used) thin film by 0.5 mm (0.020 in)
width and 10 mm (0.39 in) length.

Cruise Control
The cruise control automatically controls car speed and allows
the car to run at a constant speed without depressing the
accelerator pedal. In operation, when the driver sets a desired
speed with the cruise control switch, the built-in micro-
computer compares the speed set in the memory with the
actual running speed detected by feedback signals from the
speedometer. This feedback system operates the throttle to
correct the speed difference, thereby keeping the car at a con·
stant speed.
The major components are as follows:
• Main switch ..... built in LH control wing
• Cruise switch
mounted on steering wheel
• Control unit .... inside the instrument panel, above
glove box (One end is inserted into
panel, and the other end is secured
with screws.)
• Vacuum pump and
Valve ASSY ..... mounted on RH strut in engine room
• Actuator . . . . . . . mounted on front bulkhead bracket in
engine room
• Clutch switch .... mounted on pedal bracket
• Stop
