HINT:
When 2 or more codes are indicated, the lowest numbered code will be displayed first.
If the inspection ”Proceed to next circuit inspection shown on matrix chart” is given in the flow chart
for each circuit, proceed to the circuit with the next highest number in the table to continue check.
If the trouble still reappears even though there are no abnormalities in any of the other circuits, then
check or replace the cruise control ECU as the last step.
(*) When the vehicle speed decrease on uphill roads, the speed can be set again and driving continued. (This
is not a malfunction.)

INSPECTION PROCEDURE
1 Check actuator motor.
PREPARATION:
(a) Remove cruise control actuator.
(b) Disconnect actuator connector.
CHECK:
(a) Connect positive + lead to terminal 5 and negative − lead
to terminal 4 of actuator connector (Magnetic clutch ON).
NOTICE:
Do not connect the high tension cables to the wrong bat-
tery terminal.
You will damage the cruise control actuator.
(b) When battery positive voltage is applied to each terminal
of actuator connector, check that the control plate moves
smoothly without hesitating.
Moving directionTerminal No. to connect
Acceleration sidePositive + − 6Negative − − 7
Deceleration sidePositive + − 7Negative − − 6
(c) With the motor rotating as in 2., check that the motor is
stopped by limit switches when the control plate moves to
fully opened or fully closed position.
NG Replace actuator assembly.
OK
2 Check harness and connector between cruise control ECU and actuator motor
(See page IN−30).
NG Repair or replace harness or connector.
OK
Proceed to next circuit inspection shown on matrix chart (See page DI−336).
However, when DTC 11, 14 is displayed, check and replace cruise control ECU.

METER, ANALOG
Current flow activates a magnetic
coil which causes a needle to
move, thereby providing a relative
display against a background
calibration. LED (LIGHT EMITTING DIODE)
Upon current flow, these diodes
emit light without producing the
heat of a comparable light. IGNITION COIL
Convert low-voltage DC current
into high-voltage ingition current
for firing the spark plugs. 1. SINGLE
FILAMENT
GROUND
The point at which wiring attaches
to the Body, thereby providing a
return path for an electrical circuit;
without a ground, current cannot
flow.
Current flow causes a headlight
filament to heat up and emit light.
A headlight may have either a
single (1) filament or a double (2)
filament. BATTERY
Stores chemical energy and
converts it into electrical energy.
Provides DC current for the auto's
various electrical circuits.
CAPACITOR (Condenser)
A small holding unit for temporary
storage of electrical voltage.
CIRCUIT BREAKER
Basically a reusable fuse, a circuit
breaker will heat and open if too
much current flows through it. Some
units automatically reset when cool,
others must be manually reset.
DIODE
A semiconductor which allows
current flow in only one direction.
DIODE, ZENER
A diode which allows current flow
in one direction but blocks reverse
flow only up to a specific voltage.
Above that potential, it passes the
excess voltage. This acts as a
simple voltage regulator.
PHOTODIODE
The photodiode is a semiconductor
which controls the current flow
according to the amount of light.
FUSE
A thin metal strip which burns
through when too much current
flows through it, thereby stopping
current flow and protecting a
circuit from damage.
FUSIBLE LINK
A heavy-gauge wire placed in
high amperage circuits which
burns through on overloads,
thereby protecting the circuit.
The numbers indicate the cross-
section surface area of the wires.HORN
An electric device which sounds a
loud audible signal.
LIGHT
Current flow through a filament
causes the filament to heat up
and emit light.
METER, DIGITAL
Current flow activates one or
many LED's, LCD's, or fluorescent
displays, which provide a relative
or digital display.
MOTOR
A power unit which converts
electrical energy into mechanical
energy, especially rotary motion. CIGARETTE LIGHTER
An electric resistance heating
element.
DISTRIBUTOR, IIA
Channels high-voltage current
from the ignition coil to the
individual spark plugs.2. DOUBLE
