5. IF NECESSARY, REPAIR DEFOGGER WIRE
(a) Clean the broken wire tips with grease, wax and silicone
remover.
(b) Place the masking tape along both sides of the wire for
repair.
(c) Thoroughly mix the repair agent (Dupont paste No.
4817).
(d) Using a fine tip brush, apply a small amount of the agent
to the wire.
(e) After a few minutes, remove the masking tape.
(f) Do not repair the defogger wire for at least 24 hours.
6. w/ Mirror heater:
INSPECT MIRROR HEATER OPERATION
(a) Connect the positive (+) lead from the battery to terminal
5 and the negative (-) lead to terminal 12.
(b) Check that the mirror becomes warm.
HINT:
It will take a short time for the mirror to become warm.

3. INSPECT ENGINE ROOM R/B RELAY CIRCUIT (See
Pase BE-15)
HINT:
The mirror heater relay is built in engine room junction block.
Also the relay is constructed with a relay block that is in the junc-
tion block as a unit. To disconnect the wire harness connecting
with relay block is impossible. If the relay has a malfunction, re-
place it with junction block assembly wire harness together.
4. INSPECT DEFOGGER WIRE
NOTICE:
When cleaning the glass, use a soft, dry cloth, and wipe the
glass in the direction of the wire. Take care not to damage
the wires.
Do not use detergents or glass cleaners with abrasive in-
gredients.
When measuring voltage, wrap a piece of tin foil around the
tip of the negative probe and press the foil against the wire
with your finger, as shown.
(a) Turn the ignition switch ON.
(b) Turn the defogger switch ON.
(c) Inspect the voltage at the center of each heat wire, as
shown.
VoltageCriteria
Approx. 5VOkay (No break in wire)
Approx. 10V or 0VBroken wire
HINT:
If there is approximately 10 V, the wire is broken between the
center of the wire and the positive (+) end. If there is no voltage,
the wire is broken between the center of the wire and ground.
(d) Place the voltmeter positive (+) lead against the defogger
wire on the battery side.
(e) Place the voltmeter negative (-) lead with the foil strip
against the wire on the ground side.
(f) Slide the positive (+) lead from battery to ground side.
(g) The point where the voltmeter deflects from several V to
zero V is the place where the defogger wire is broken.
HINT:
If the heat wire is not broken, the voltmeter indicates 0 V at the
positive (+) end of the heat wire but voltage gradually increases
to about 12 V as the meter probe moves to the other end.

If a code can not be registered, observe the following condi-
tions.
HINT:
If the battery of original transmitter is consumed.
Press the switch of the transmitter repeatedly in registra-
tion mode, as some transmitters stop transmitting for 1 to
2 seconds.
This system is not applicable to the garage door opener
which had been made before 1982.
2. CODE DELETION
(a) Press the switches at both ends of garage door opener
simultaneously for 20 seconds.
HINT:
When transferring to deletion mode, LED (red) blinks in 6 Hz
cycle.
(b) When releasing the switch within 10 seconds after trans-
ferring to deletion mode, all the registered codes will be
erased.
HINT:
Press the switch until blinking in 6 Hz cycle stops, so that the
default code for check is set.
