SHIFT LOCK MECHANISM CHECK

M1232001000343

1. Perform the following inspections.

2. When any of the above shift lock inspection procedures fail,

adjust the shift lock cable as follows:

(1) Remove the floor console. (Refer to GROUP 52A

− Floor

Console

P.52A-40

.)

(2) Shift the selector lever to the "P" position.
(3) Loosen the lock nut on the shift lock cable.
(4) Adjust the cable so that the end of the shift lock cable is

above the red line on the lock cam and tighten the
locknut.

Tightening torque: 12 N

⋅m (106 in-lb)

(5) After adjusting, retest the shift lock cable operation.

Replace the shift lock cable if it does not operate
properly. (Refer to

P.23A-451

.)

(6) Install the floor console.

TRANSMISSION FLUID TEMPERATURE SENSOR
CHECK

M1231104200027

1. Remove the transmission fluid temperature sensor.
2. Measure the resistance between terminals No.1 and No.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 "A/T TEMP" indicator
light is illuminating, replace the transmission fluid
temperature sensor.
NOTE: The "A/T TEMP" indicator light on the combination
meter illuminating when the temperature reaches approxi-
mately 125

A/T CONTROL RELAY CHECK

M1231110300131

1. Remove the A/T control relay.

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

to the negative battery terminal and terminal 4 to the positive
battery terminal.

3. Check for continuity between A/T control relay terminals 1

and terminal 3 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

M1231110400138

1. Use scan tool MB991502 to measure the transmission fluid

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

°C (68°F).

2. Remove the solenoid valve harness and transmission fluid

temperature sensor 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.

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.
