WAVEFORM CHECK USING AN OSCILLOSCOPEM1161001200124
MEASUREMENT METHODConnect the oscilloscope special patterns pick-up to
the alternator "B" terminal.
STANDARD WAVEFORM
Observation Conditions
NOTE:
The voltage waveform of the alternator "B" terminal
can undulate as shown in the illustration. This
waveform is produced when the regulator operates
according to fluctuations in the alternator load (current), and is normal for the alternator. In addition,
when the voltage waveform reaches an excessively
high value (approximately 2 V or higher at idle), it
often indicates an open circuit due to a brown fuse
between alternator "B" terminal and battery, but not a
defective alternator.

DOOR WINDOW GLASS ADJUSTMENTM1423001000327
Check that the door glass moves while contacting
the door glass channel when it is raised and lowered
fully. If not, adjust the door window according to the
following procedures.
1. Remove the door trim assembly (Refer to GROUP
52A, Door trim P.52A-15).
2. Remove the waterproof film (Refer to P.42-39).
3. Loosen the door glass mounting screw via the
adjusting hole with the door window glass fully
closed, then lower the window glass a little.
4. Fully close the door window glass again and
tighten the door glass mounting screw firmly via
the adjusting hole.
GLASS SLIDING MECHANISM CHECK
AND ADJUSTMENT
M1429000900091
If the window glass automatically starts moving
downwards at the wrong time while it is being raised,
carry out the following adjustment or replacement
procedures.
1. Remove the door trim assembly (Refer to GROUP
52A, Door trim P.52A-15).
2. Remove the waterproof film (Refer to P.42-39).
3. Remove the window regulator assembly from the
door window glass, and then raise and lower the
door window glass by hand to check the operation
force.
NOTE: Insert a cushion or similar object to
prevent damage to the glass if it should happen to
fall down.4. If the door window glass does not move up and
down smoothly, check or repair the following
points.
•Check the installation condition of the
runchannel.
•Repair any twisting in the door sash.
•Check the installation condition of the lower sash
or the centre sash.
NOTE: The lower sash cannot normally be
adjusted, but it may be possible to adjust the sash
span slightly within the range allowed by
manufacturing tolerances by pushing the lower
sash outwards while re-installing it.
5. If repair or adjustment is not possible, replace the
door assembly.
POWER WINDOW OPERATING CURRENT
CHECK
M1429001100184
1. Remove the power window fuse and connect an
ammeter as shown in the illustration.
2. When the power window switch is pressed to the
“UP” position, a large amount of current flows at
the time the window starts to close and when it is
fully closed, so measure the operation current in
the interval between these two points.
Standard value (A): 5 ± 1A (Power supply
voltage 14.5 ± 0.5V, 25°C)

Dimmer interior lamp control function
The room lamp off is delayed by ETACS-ECU. The
lamps off delay time vary according to the conditions.
The control details are as follows. The lamp delay off
Yes/NO and delay time can be set with the settings
(adjustment function). for adjustment methods and
adjustment details (post-adjustment operations).
•ADJUSTMENT PROCEDURE
•Not using SWS monitor: GROUP 54B,
P.54B-423.
•The room lamp lights up if the ignition switch is at
the "LOCK" (OFF) position and either of the
doors are opened (either of the door switches:
ON). At this time, if all doors are closed (all door
switches: OFF) then the lamp will gradually dim
down to lamps off in about 15 seconds.
NOTE: When the lamps are dimmed and the ignition
switch is turned ON or if the door is locked, then
the dimming operations stop and the lamps are
turned OFF.
•When the ignition switch is at the ON position and
one of the doors are opened (one of the door
switches: ON) then the room lamp will light up. At
this time, if all doors are closed (all door switches:
OFF) then the lamps will dim out.
•When the ignition key is pulled out the room lamp
lights up and then will dim out in 15 seconds. The
lamp will dim out if the ignition key is inserted
again and the door is locked while the timer is
activated.
The room lamp is controlled by the Smart Wiring
System (SWS). For troubleshooting, refer to
respective Groups below.•Not using SWS monitor: GROUP 54B, SWS
Troubleshooting P.54B-38.
•Using SWS monitor: GROUP 54C, SWS
Troubleshooting P.54C-22.
Interior lamp automatic shutdown
function
The interior lamp automatic shutdown function, dims
out the room lamp and other interior lamps by
activating the keep relay built-in the ETACS-ECU
when the ignition switch is OFF and the
multi-purpose fuse loaded signals built-in the
ETACS-ECU is ON and 30 minutes passes. The
lamps lights back up if the ignition switch is turned to
the ON position or either of the doors is opened
(either of the door switches: ON). The function
Yes/No feature can be changed with the settings
(adjustment function). for adjustment methods and
adjustment details (post-adjustment operations).
•ADJUSTMENT PROCEDURE
•Not using SWS monitor: GROUP 54B,
P.54B-423.
The head lamp are controlled by the Smart Wiring
System (SWS). For troubleshooting, refer to
respective Groups below.
•Not using SWS monitor: GROUP 54B, SWS
