STEERING -On-vehicle Service37A-9
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

DIAGNOSIS CODE INSPECTION PROCEDURES
Code No. 11 ETACS-ECU-related failureProbable cause
The ETACS-ECU monitors its own communication data, outputting this diagnosis
code when data error occurs 15 consecutive times (for 0.6 seconds). The
diagnosis code output stops when the ETACS-ECU confirms that its data was
transmitted normally 15 consecutive times (for 0.6 seconds).DETACS-ECU fault
Replace ETACS-ECU.
Code No. 12 Column switch-related fault or fault in
connecting to ETACS-ECUProbable cause
This diagnosis code is output when a column switch outputs a signal (at least
three times a second) that is not in accordance with the transmission request
signal from ETACS-ECU. The diagnosis code output stops when the column
switch continuously outputs for one second a signal that accords with the
transmission request signal from ETACS-ECU.DColumn switch fault
