TROUBLESHOOTING <CVT KEY INTERLOCK AND SHIFT LOCK MECHANISMS>

CVT

23A-131

Inspection Procedure 6: The ignition key cannot be turned to the LOCK (OFF) position when the
selector lever is at the P position.

COMMENTS ON TROUBLE SYMPTOM

The cause is probably a malfunction of the selector
lever assembly, key interlock cable or engine starting
switch assembly.

PROBABLE CAUSES

• Malfunction of selector lever assembly

• Malfunction of key interlock cable

• Malfunction of engine starting switch assembly

DIAGNOSIS PROCEDURE

Check by referring to the possible causes.

Inspection Procedure 7: The ignition key can be turned to the LOCK (OFF) position when the selector
lever is at a position other than the P position.

COMMENTS ON TROUBLE SYMPTOM

The cause is probably a malfunction of the key inter-
lock cable or engine starting switch assembly.

PROBABLE CAUSES

• Malfunction of key interlock cable

• Malfunction of engine starting switch assembly

DIAGNOSIS PROCEDURE

Check by referring to the possible causes.

TRANSMISSION FLUID (CVT FLUID)
CHECK

M1231200900054

CAUTION

When replacing the transmission with a new one,
overhauling the existing transmission, or driving
in a harsh condition, the CVT fluid cooler line
should always be flushed out and CVT fluid
should be replaced with a new one.
1. Drive the vehicle until the CVT fluid temperature

reaches the normal temperature (70

− 80°C)

NOTE: Measure CVT fluid temperature using
M.U.T.-III.

gauge

Check the oil level referring to the characteristics
chart shown at left if it takes some time to reach
the normal operation temperature of CVT fluid (70

2. Park the vehicle on a level surface.
3. Move the selector lever to all positions to fully

charge the torque converter and the fluid lines
with CVT fluid, and then move the selector lever
to the N position.

4. After wiping away any dirt from around the oil

level gauge, pull out the oil level gauge and check
the level of CVT fluid.

NOTE: If the CVT fluid has a burnt smell, or if it
has become very contaminated or dirty, it means
that the CVT fluid has become contaminated by
minute particles form bushings (metal) or worn
parts. In such a case, the transmission needs to
be overhauled and the CVT fluid cooler line needs
to be flushed out.

AC005861

5. Check that the CVT fluid level is between the HOT

marks on the oil level gauge. If the CVT fluid level
is too low, add more CVT fluid until the level
reaches between the HOT marks.

CVT fluid: DIA QUEEN ATF SP III

NOTE: If the CVT fluid level is too low, the oil
pump draws air into the system along with the
CVT fluid, and air bubbles will thus from in the
fluid circuit. This will cause a drop in fluid pressure
and cause the shift points to change and the
clutches and brakes to slip. If the CVT fluid level is
too high, the gear will churn the CVT fluid and
cause bubbles to develop, which can then cause
the same problems as when the CVT fluid is too
low. In either case, the air bubbles can cause
overheating and oxidation of the CVT fluid, and
also prevent the valves, clutches and brakes from
operating normally. In addition, if bubbles develop
in the CVT fluid, the CVT fluid can overflow from
the transmission vent holes and be mistaken for
leaks.

6. Securely re-insert the oil level gauge.

TRANSMISSION FLUID (CVT FLUID)
REPLACEMENT

M1231201000117

CAUTION

Before replacing the transmission with a new
one, overhauling the existing transmission, or
connecting the cooler pipe to the transmission,
the CVT fluid cooler line should always be
flushed out.
In you have an CVT fluid changer, use the CVT fluid
changer to flush the CVT fluid. If you do not have an
CVT fluid changer, follow the procedure given below.

AC402911AD

1. Disconnect the hose shown in the figure through

which the CVT fluid flows from the ATF warmer
(ATF cooler) to the transmission.

CAUTION

The engine should be stopped within one minute
of it being started. If the CVT fluid has all been
discharged before this, stop the engine at that
point.
2. Start the engine and discharge the CVT fluid.

Driving conditions: N range, idling

Discharge amount: Approx. 3.5 L

AC208248

3. Remove the drain plug at the bottom of the

transmission case to drain out the remaining CVT
fluid.

Discharge amount: Approx. 2.0 L

4. Install the drain plug with a gasket in between,

and tighten it to the specified torque.

Tightening torque: 32

± 2 N⋅m

CAUTION

Stop pouring in the CVT fluid once 5.5 L has been
poured in.
5. Pour in new CVT fluid through the oil filler tube.

Amount to add: Approx. 5.5 L

6. Repeat the operation in step 2.
7. Pour in new CVT fluid through the oil filler tube.

Amount to add: Approx. 3.5 L

NOTE: Carry out steps 2 and 7 so that at least 8.0
L has been discharged from the cooler hose. After
this, discharge a small quantity of CVT fluid and
check for contamination. If the CVT fluid is con-
taminated, repeat steps 6 and 7.

AC402911AD

8. Connect the hose which was disconnected in step

1, and then securely re-insert the oil level gauge.

9. Start the engine, and let it run at idle for 1

− 2

minutes.

10.Move the selector lever to all positions once, and

then return it to the N position.

AC005861

11.Check that the CVT fluid level on the oil level

gauge is at the COLD mark. if it is not up to this
mark, add more CVT fluid.

12.Drive the vehicle until the CVT Fluid temperature

reaches the normal temperature (70

− 80°C), and

then re check the CVT fluid level.
NOTE: The COLD mark is for reference only; the
HOT marks should be used as the standard for
judgment.
NOTE: CVT fluid temperature using M.U.T.-III.

13.When CVT fluid is under the specified level, top

up CVT fluid. When CVT fluid is over the specified
level, drain the excessive CVT fluid from the drain
plug to adjust CVT fluid level to the specified level.

14.Securely insert the oil level gauge into the oil filler

tube.

the CVT fluid cooler line must always be flushed
out.
