cloth dampened alcohol.
2.
Apply a small amount of conductive silver composition to tip of
drawing pen.
Shake silver composition container before use.
3.
Place ruler on glass along broken line. Deposit conductive silver
composition on break with drawing pen. Slightly overlap existing
heat wire on both sides [preferably 5 mm (0.20 in)] of the break.
4.
After repair has been completed, check repaired wire for conti-
nuity.This check should be conducted 10 minutes after silver
composition is deposited.
Do not touch repaired area while test is being conducted.
5.
Apply a constant stream of hot air directly to the repaired area
for approximately 20 minutes with a heat gun. A minimum dis-
tance of 3 cm (1.2 in) should be kept between repaired area and
hot air outlet.
If a heat gun is not available, let the repaired area dry for 24

System Description
AIS001H5
●
When switching the door mirror remote control switch position (LH/RH), the system moves driver or pas-
senger door mirror face downward, in relation to the A/T selector lever being shifted to Reverse Position.
●
The mirror position with the reverse gear engaged can be adjusted and the adjusted mirror position can
be stored in memory (2 positions).
●
With reverse gear-linked operation signal, the driver side door mirror control unit (LCU 03) and passenger
side door mirror control unit (LCU 04) installed on the door panel drives and controls the motors (UP/
DOWN, LH/RH).
●
Using the self-diagnostic function and CONSULT-II, system diagnosis can be performed.
