REPAIR
1. INSPECT WINDOW GLASS (ANTENNA WIRE)
NOTICE:
When cleaning the glass, wipe it in the direction of the wire
with a soft and dry cloth. Take care not to damage the wire.
Do not use detergents or glass cleaners with abrasive in-
gredients. When measuring voltage, wind a piece of tin foil
around the tip of the tester probe and press the foil against
the wire with your finger, as shown in the illustration.
(a) Check the continuity, at the center of each antenna wire,
as shown in the illustration.
2. REPAIR WINDOW GLASS (ANTENNA WIRE)
(a) Clean the broken wire tips with a grease, wax and silicone
remover.
(b) Place the masking tape along both sides of the wire to be
repaired.
(c) Thoroughly mix the repair agent (Dupont paste No.4817).
(d) Using a fine tip brush, apply a small amount of the mixture
to the wire.
(e) After a few minutes, remove the masking tape.
(f) Do not repair the defogger wire for at least 24 hours after-

ON±VEHICLE INSPECTION
1. INSPECT BRAKE BOOSTER
(a) Airtightness check.
(1) Start the engine and stop it after 1 or 2 minutes. De-
press the brake pedal several times slowly.
HINT:
If the pedal can be depressed to the f;oor the first time, but on
the 2nd or 3rd time cannot be depreesed as far, the booster is
airtight.
(2) Depress the brake pedal while the engine is run-
ning, and stop the engine with the pedal depressed.
HINT:
If there is no change in the pedal reserve distance after holding
the pedal for 30 seconds, the booster is airtight.
(b) Operating check.
(1) Depress the brake pedal several times with the igni-
tion switch off and check that there is no change in
the pedal reserve distance.
(2) Depress the brake pedal and start the engine.
HINT:
If the pedal goes down slightly, operation is normal.
2. INSPECT VACUUM CHECK VALVE
(a) Inspect vacuum check valve.
(1) Slide the clip and disconnect the vacuum hose.
(2) Remove the vacuum check valve.
(3) Check that there is ventilation from the booster to
the engine, and no ventilation from the engine to the
booster.
(4) If any fault is found, replace the vacuum check
valve.
