IGNITION SYSTEM
GENERAL INFORMATIONM1163000100294
This system is equipped with two ignition coils (A and
B) with built-in power transistors for the No. 1 and
No. 4 cylinders and the No. 2 and No. 3 cylinders
respectively.
Interruption of the primary current flowing in the
primary side of ignition coil A generates a high
voltage in the secondary side of ignition coil A. The
high voltage thus generated is applied to the spark
plugs of No. 1 and No. 4 cylinders to generate
sparks. At the time that the sparks are generated at
both spark plugs, if one cylinder is at the
compression stroke, the other cylinder is at the
exhaust stroke, so that ignition of the compressed
air/fuel mixture occurs only for the cylinder which is
at the compression stroke.
In the same way, when the primary current flowing in
ignition coil B is interrupted, the high voltage thus
generated is applied to the spark plugs of No. 2 and
No. 3 cylinders.The engine-ECU or engine-A/T-ECU
turns the two power transistors inside the ignition
coils alternately on and off. This causes the primary
currents in the ignition coils to be alternately
interrupted and allowed to flow to fire the cylinders in
the order 1-3-4-2.
The engine-ECU or engine-A/T-ECU
determines which ignition coil should be controlled
by means of the signals from the camshaft position
sensor which is incorporated in the camshaft and
from the crank angle sensor which is incorporated in
the crankshaft. It also detects the crankshaft position
in order to provide ignition at the most appropriate
timing in response to the engine operation
conditions. It also detects the crankshaft position in
order to provide ignition at the most appropriate
timing in response to the engine operation
conditions.
When the engine is cold or operated at high
altitudes, the ignition timing is slightly advanced to
provide optimum performance.
When the automatic transmission shifts gears, the
ignition timing is also retarded in order to reduce
output torque, thereby alleviating shifting shocks.

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)

CAUTION
The anti-trap function does not work until the
power window switch completes learning the
fully closed position (It is because the anti-trap
function is reset).
3. Operate the power window switch and fully close
the door window glass. The power window
activates for 0.7 seconds and stops automatically
when the power window switch is pressed once.
Repeat this operation until the door window glass
fully closes and release the switch once. Then,
hold the power window switch to the fully closed
side again for one second so that the power
window switch completes learning the fully closed
position.
NOTE: If the power window switch is operated to
open the door window glass while the switch is
learning, learning will be cancelled. If this
happens, return to step 2.
How to make the power window switch
learn the fully closed position when the
power window switch is replaced with a
new one
CAUTION
The anti-trap function does not work until the
power window switch completes learning the
fully closed position (It is because the anti-trap
function is reset).
Operate the power window main switch to fully close
the door window glass by one-shot up action so that
the power window switch will complete learning
(Initialisation is not needed).
NOTE: When the power window sub switch of each
seat is replaced, operate the power window main
switch to fully close the applicable power window by
one-shot up action (It is because the power window
sub switch does not have one-shot up/down
function).

HOW TO REGISTER SECRET CODEM1428001000292
Each individual secret code is registered inside the
transmitter, and so it is necessary to resister these
codes with the EEPROM inside the receiver in the
following cases.
•When the transmitter or ETACS-ECU is replaced
•If more transmitters are to be used
•If it appears that a problem is occurring because
of faulty registration of a code.
A maximum of four different codes can be stored in
the EEPROM memory (four different transmitters can
be used). When the code for the first transmitter is
registered, the previously registered codes for all
transmitters are cleared. Therefore, if you are using
four transmitters or are adding more transmitters, the
codes for all transmitters must be registered at the
same time.
