2. Loosen the control cable to the manual control lever

coupling nut to free the cable and lever.

3. Set the manual control lever to the neutral position.

4. Loosen the transmission range switch body mounting bolts

and turn the transmission range switch body so the hole in
the end of the manual control lever and the hole (section A

−

A in the figure on the left) in the flange of the transmission
range switch body flange are aligned.
NOTE: The transmission range switch body can be aligned
by inserting a 5-mm diameter steel bar into the end hole of
the manual control lever and the flange hole of the transmis-
sion range switch body.

5. Tighten the transmission range switch body mounting bolts

to the specified torque. Be careful at this time that the switch
body does not move.

Tightening torque: 11

± 1 N⋅m (96 ± 8 in-lb)

6. Gently push the transaxle control cable in the direction of the

arrow, until the cable is taut. Tighten the adjusting nut.

Tightening torque: 12

± 2 N⋅m (102 ± 22 in-lb)

7. Check that the selector lever is in the "N" position.
8. Check that each position of the manual control lever

matches each position of the selector lever using scan tool
MB991958.

TRANSMISSION FLUID TEMPERATURE SENSOR
CHECK

M1231021800036

1. Remove the transmission fluid temperature sensor.
2. Measure the resistance between terminals 1 and 2 of the

transmission fluid temperature sensor connector.

Standard value:

3. If the transmission fluid temperature sensor resistance is

outside the specified range and the "N" range indicator light
is flashing, replace the transmission fluid temperature
sensor.
NOTE: The "N" range indicator light on the combination
meter flashes when the temperature reaches approximately
125

°

C (257

°

F) or greater, and then stops flashing when the

temperature drops below approximately 115

°

C (238

A/T CONTROL RELAY CHECK

M1231009300118

1. Remove the A/T control relay.
2. Use jumper wires to connect the A/T control relay terminal 2

to the positive battery terminal and terminal 3 to the negative
battery terminal.

3. Check the continuity between terminal 1 and terminal 4 of

the A/T control relay when the jumper wires are connected
to and disconnected from the battery.

4. If there is any problem with the A/T control relay, replace it.

SOLENOID VALVE CHECK

M1231009400234

1. Use scan tool MB991958 (MUT-III sub assembly) to

measure the transmission fluid temperature. The desired
transmission fluid temperature setting for performing the
solenoid valve check is 20

°C (68°F).

2. Remove the A/T control solenoid valve assembly connector.
3. Measure the resistance between the solenoid valve

terminals.

4. The measured resistance of the solenoid valve when the

transmission fluid temperature is 20

°C (68°F) should match

the specified resistance on the chart below.

Specified resistance:

5. If the solenoid valve resistance is within the specified range,

check the power supply and the ground circuits.

6. If the solenoid valve resistance is not within the specified

range, drain the transmission fluid and remove the valve
body cover.

7. Disconnect the connector of any solenoid valves that are not

within the specified range.

8. Measure the resistance between terminals 1 and 2 of any

solenoid valve that was not within the specified range.

Specified resistance: 2.7

− 3.4 Ω [at 20°C (68°F)]

9. If the resistance is not within the specified range, replace the

solenoid valve.

10.If the resistance is within the specified range, check the

wiring harness between the affected A/T control solenoid
valve assembly and the solenoid valve. If a problem is not
found in the above steps, check the solenoid valve O-rings
and replace them if necessary.

SELECTOR LEVER OPERATION CHECK

M1231001300396

1. Apply the parking brake, and check that the selector lever

moves smoothly and accurately to each position.

2. Check that the engine starts when the selector lever is in the

"N" or "P" position, and that it does not start when the
selector lever is in any other position.

3. Start the engine, release the parking brake, and check that

the vehicle moves forward when the selector lever is moved
from the "N" position to the "D," "3," "2" or "L" position or 1st
or 2nd gear in sport mode, and that the vehicle reverses
when the selector lever is moved to the "R" position.

4. Stop the engine.
5. Turn the ignition switch to the "ON" position, and check that

the backup lamp illuminates when the selector lever is
shifted from the "P" to the "R" position.
NOTE: The A/T mis-operation prevention mechanism pre-
vents movement of the selector lever from the "P" position if
the ignition switch is in a position other than "LOCK" (OFF)
and the brake pedal is not depressed.
