ENGINE ELECTRICAL -Ignition System16-26
IGNITION SYSTEM
GENERAL INFORMATION
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 turns the two power transistors
inside the ignition coils alternately on and off. Thiscauses 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 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.

If the vehicle has been run, leave it for 90 min. or more
in an ordinary temperature (10_C–30_C) to allow the
accumulator internal pressure to drop.
NOTE
If the ambient temperature is 10_C or less, allow more
time to leave the vehicle to stand idle.

the ignition switch, perform MUT-IIactuator test (Item
No.03), forcibly drive the hydraulic unit and remove the
pressure in the accumulator.
Caution
Turn the ignition switch to the “LOCK”(OFF) position
before connecting or disconnecting the MUT-II.
NOTE
(1) In the actuator test (Item No. 03: Oil Level Check
Mode), the directional valve of the hydraulic unit is
moved to the left and right for 20 times, and then
the differential is cleared automatically. Drive can also
be cleared forcibly using the Clear key of the MUT-II.
(2) If the function has been stopped by fail-safe, the
hydraulic unit cannot be cleared forcibly.

STEERING -General Information37A-2
GENERAL INFORMATION
The system has been equipped with the MOMO
leather 3-spoke-type steering wheel with built-in
SRS airbag.
The steering column is equipped with tilt steering
mechanism.
The power steering is an integral rack and piniontype that combines the steering gear and linkage
into one light-weight and compact assembly.
The steering system uses a vane oil pump with
a fluid flow control system, so that steering effort
varies with engine speed.

POWER STEERING FLUID LEVEL CHECK
1. Park the vehicle on a flat, level surface, start the engine,
and then turn the steering wheel several times to raise
the temperature of the fluid to approximately 50 - 60_C.
2. With the engine running, turn the wheel all the way to
the left and right several times.
3. Check the fluid in the oil reservoir for foaming or milkiness.
Check the difference of the fluid level when the engine
is stopped, and while it is running. If the change of the
fluid level is 5 mm or more, air bleeding should be done.
POWER STEERING FLUID REPLACEMENT
1. Raise the front wheels on a jack, and then support them
with rigid racks.
2. Disconnect the return hose connection.
3. Connect a vinyl hose to the return hose, and drain the
oil into a container.
4. Disconnect the ignition coil connectors. (Refer to
GROUP16 - Ignition System.)
5. While operating the starting motor intermittently, turn the
steering wheel all the way to the left and right several
times to drain all of the fluid.
6. Connect the return hoses securely, and then secure it
with the clip.
7. Fill the oil reservoir with specified fluid up to the lower
position of the filter, and then bleed air.
Specified fluid:
Automatic transmission fluid DEXRONII
Caution
Do not use ATF-SPIIM and ATF-SPIII.
POWER STEERING SYSTEM BLEEDING
1. Jack up the vehicle and support the front wheels with
rigid racks.
2. Disconnect the ignition coil connectors. (Refer to
GROUP16 - Ignition System.)
3. Cranking the engine with the starter several times
intermittently (during 15 to 20 seconds), turn the steering
wheel left and right fully five or six times.
Caution
(1) During the bleeding, refill the fluid so that the
level never falls below the lower position of the
filter.
(2) Be sure to bleed air only while cranking. If the
bleeding is done with the engine running, the air
will be broken up and absorbed into the fluid.
4. Connect the ignition coil connectors and idle the engine.
5. Turn the steering wheel left and right fully until no bubbles
comes out in the oil reservoir.
6. See that the fluid is not milky and that the fluid level
is up to the specified position on the level gauge.
7. See that the fluid level changes little when the steering
wheel is turned left and right.
8. Check difference in fluid levels between the engine
stopped and running.
Fluid level change: Within 5 mm
