FILAMENT
inspection
1. Turn the rear window defroster switch ON.
2. Connect the (+) terminal of the voltmeter to the center of
each filament and the (-) terminal to the body. The stan-
dard voltage at the center of each filament is approximate-
ly 6V. If the meter indication is high, there is a short circuit
between the center and the grounded side of the filament.
If the indication is low or zero, the malfunction is between
the center and positive side.
Repairing
7. Use paint thinner or ethyl alcohol to clean the damaged part
of the filament.
2. Attach tape to both sides of the damaged part of the filament.
3. Using a small brush or marking pen, coat the damaged part
with silver paint (part no. 2835 77 600) or equivalent.
4. Let the paint set for 24 hours at 25OC (77OF) to let it dry
completely. (If a blow dryer is used to heat it to 150°C
(302OF), it can be dried in about 30 minutes.)
Note
l Do not use the rear window defroster until the paint
is dry.
l Do not use gasoline or sDmiiar solvents to clean the
damaged part.

CRUISE CONTROL SYSTEM I
TROUBLESHOOTING GUIDE
General Note
Troubleshooting and inspection of the cruise control is done in two steps. First is the quick, self-diagnostic
inspection using the built-in self-diagnostic function, cruise control switch, and test light. The other is a detailed
inspection of parts using a voltmeter and an ohmmeter.

Step 1: Self-diagnostic Inspection
(Self-diagnosis of malfunction)
Check for condition code(s) memorized in the cruise control
unit by using the cruise control switch and test light.
(Refer to page T-81 .)
If no condition code exists, go to Step 2.
If a condition code(s) is indicated, go to Step 3.
Step 2: Self-diagnostic Inspection
(Quick inspection of cruise control system)
Verify operation codes by using the cruise control switch and
test light. (Refer to page T-82.)
If the operation code is correctly indicated, the part under in-
spection is OK.
If an operation code is not indicated, go to Step 3.
Step 3: Inspection of Circuit and Parts
Check the cruise control wiring and parts with a voltmeter and
an ohmmeter. (Refer to page T-86.)
Adjustment
Checking free play of actuator inner cable
Remove the clip and adjust the nut so that the actuator con-
trol cable play is as follows when the cable is pressed lightly.
Free play of actuator inner cable:
l--5mm (0.039-0.197 in)

CRUISE CONTROL SYSTEM
SELF-DIAGNOSTIC INSPECTION
Self-diagnostic Function
The Self-diagnostic function intergrated within the cruise control unit diagnoses the condition of the cruise
control system.
Condition/operation codes are indicated by flashing of the test light connected to the control unit. (Refer to
condition code numbers on page T-80.) This operation continues until canceled.
23UOTX.052
Principle of Code Cycle
Condition and operation codes are determined by flashing of the test light connected to the control unit as
shown below.
03UOTX.140
1. Code cycle break
The time between condition/operation code cycles is 4.0 seconds (the time the lamp is off).
