5A-68 AUTOMATIC TRANSMISSION
Description / Cause
The signal from the mode switch is unreliable.
This fault is caused by too many changes in the mode input signal
over a period of time. Typical causes would be an intermittent connec
tion in the switch or wiring or an intermittent short to ground in the
wiring.
The data link between the TCU and the engine management module
is found to be unreliable because the checksum, or the data received,
did not match the correct checksum.
This could be caused by an open circuit, short circuit to ground or a
loose connection in the link wire itself.
Each solenoid in turn is switched off if it was energised, or switched on
if it was not energised by a very small 100 ms pulse. This pulse is too
short for the solenoid to react so transmission operation is not af
fected.
The solenoid feedback voltage is measured before the 100 ms pulse
and again during the pulse. If the difference is outside the acceptable
limits the relevant fault messages are set.
Typical causes would be an open circuit in the wiring to or within the
solenoid, or a short circuit to ground in the wiring to, from or within the
solenoid in question.
If several of these fault codes are presents check the wiring or
connectors that are common to the selected solenoids, especially the
earth connections.
The state of the solenoid feedback voltage is outside acceptable
limits but the faulty solenoid could not be isolated.
The current to solenoid 5 was outside acceptable limits.
This fault results from a mismatch between the current set point for
solenoid 5 and the current measured by the feedback within the TCU.
Typical causes would be an open circuit or short circuit to ground in
the wiring to, from or within the solenoid. It is also possible that there
has been a fault in the solenoid output circuit. If this is the case
however, the fault should be continually present.
The closed throttle position has not been learnt. This fault
may be caused by the transmission not having reached normal
operating temperature or the engine idle speed being incorrect.
The TCU will learn the closed throttle position automatically
when the transmission is brought to normal operating
temperature and the engine is allowed to idle in Drive with the
‘base idle’ correctly set and the air conditioner (if fitted)
switched off. Condition

Oil Level Check
lClean the oil level plug and surrounding area.
lRemove the oil level plug and check whether oil is drip
out or not.
lTighten the oil level plug.
Oil Change
lClean the oil level plug and surrounding area
lPlace a suitable container under the transfer case.
lRemove the oil and tighten the drain plug.
lFill the oil through the oil level plug until oil begins to
drip out.
lTighten the oil level plug.
Cautions for oil level check and plugs tightening
lDo not use an impact wrench to remove or tighten the

pressure gauge between the oil pump and pressure hose
2. Bleed the system . Start the engine and turn the steering
wheel form lock several times until oil temperature is up to
50°C
3. Run the engine at 1,000 rpm.

Bleeding of Power Steering System
1. Disconnect the fuel line. Using a starter motor, crank the
engine and turn the steering wheel from lock to lock 5 or 6
times.
Notice
Do bleeding with engine cranking. If bleed with idling, there
can be a air contact with oil.
2. Connect the fuel feed line and start the engine at idle speed.
3. Turn the steering wheel from lock to lock until there is no
more air in oil reservoir.
4. Connect the oil level is within specification.
