Subaru Outback: Road Test

A: INSPECTION

1. GENERAL PRECAUTION

Road tests should be conducted to properly diagnose the condition of CVT.

CAUTION: Always observe the local traffic laws when performing the test.

2. D RANGE SHIFT FUNCTION

Make sure the engine speed is 1,100 - 1,300 rpm while driving on the level road at 50 km/h (31 MPH) after accelerating from halting to 1/4 of accelerator opening angle. Then stop the vehicle. Check normal gear change has occurred while the vehicle speed changes from a constant speed to zero.

3. KICK-DOWN FUNCTION

Check if engine speed will rise by operating the accelerator opening angle to the full from a constant speed of 50 km/h (31 MPH) or more.

4. ENGINE BRAKE OPERATION

5. LOCK-UP FUNCTION

When the accelerator is lightly depressed while driving on a flat road in "D" range, check that rpm does not change abruptly.

6. P RANGE OPERATION

Stop the vehicle on an uphill grade of 5% or more and shift to the "P" range and apply the parking brake.

Check that the vehicle does not move when the parking brake is released.

7. NOISE AND VIBRATION

Check for noise and vibration during a constant driving, accelerating, decelerating and manual shift operation.

8. OIL LEAKAGE

After the driving test, inspect for leakage of CVTF and differential gear oil from the transmission body.

Stall Test

A: INSPECTION

CAUTION: Make sure no other person is around the vehicle during stall test measurement.

NOTE: Stall test is extremely important in diagnosing the condition of CVT and engine. The test is necessary to measure the engine stall speeds in "R" and "D" range.

Purposes of the stall test:

1) Place wheel chocks at the front and rear of all wheels and engage the electronic parking brake.

2) Turn the A/C OFF.

3) Using the Subaru Select Monitor, check if the throttle valve operates when you depress the accelerator pedal. <Ref. to EN(H4SO)(diag)-33, READ CURRENT DATA FOR ENGINE (NORMAL MODE), OPERATION, Subaru Select Monitor.>

4) Check the engine oil level.

5) Check the coolant level.

6) Adjust the CVTF level. <Ref. to CVT-37, ADJUSTMENT, CVTF.>

7) Increase the CVT temperature to 60 to 80ºC (140 to 176ºF) by idling the engine (with select lever set to "N" or "P" range).

8) Shift the select lever to "D" range.

9) Depress the accelerator pedal to the full while fully depressing the foot brake pedal with your left foot.

10) When the engine speed stabilizes, quickly record the engine speed and release accelerator pedal. Shift the select lever to "N" range. Let the engine idle for one minute or more to cool it down.

11) Shift to "R" range and perform the same stall test.

NOTE:

Stall speed standard: 2,400 - 3,100 rpm

Time Lag Test

A: INSPECTION

NOTE: When the select lever is shifted while the engine is idling, there will be a certain time elapse or lag before shock is felt. This symptom helps to check the condition of forward clutch and reverse brake.

1) Apply the electronic parking brake.

2) Start the engine. Check the idle speed. (A/C OFF) 3) Shift the select lever from "N" to "D" range. Using a stop watch, measure the time elapsed from shifting the lever until the shock is felt.

Time lag standard: 1.2 seconds or less

If "N" → "D" time lag is longer than specified:

4) In the same manner, measure the time lag when shifting from "N" range to "R" range.

Time lag standard: 1.5 seconds or less

If "N" → "R" time lag is longer than specified:

Secondary Pressure (Line Pressure) Test

A: INSPECTION

CAUTION: Make sure no other person is around the vehicle during secondary pressure (line pressure) test measurement.

NOTE:

1) Remove the front wheel RH. <Ref. to WT-4, REMOVAL, Tire and Wheel.>

2) Lift up the vehicle.

3) Remove the test plug for secondary pressure (line pressure).

4) Attach ST1, ST2 and ST3 to transmission.

5) Set the gauge so that it can be seen from the driver's seat.

6) Install the front wheel RH. <Ref. to WT-4, INSTALLATION, Tire and Wheel.>

7) Using the Subaru Select Monitor, check if the throttle valve operates when you depress the accelerator pedal. <Ref. to EN(H4SO)(diag)-33, READ CURRENT DATA FOR ENGINE (NORMAL MODE), OPERATION, Subaru Select Monitor.>

8) Check the engine oil level. <Ref. to LU(H4SO)-13, Engine Oil.>

9) Check the coolant level. <Ref. to CO(H4SO)-14, Engine Coolant.>

10) Adjust the CVTF level. <Ref. to CVT-37, ADJUSTMENT, CVTF.>

11) Increase the CVTF temperature to 60 - 80ºC (140 - 176ºF) by idling the engine with the select lever shifted to "N" or "P" range.

12) Shift the select lever to "D" range.

13) Depress the accelerator pedal to the full while fully depressing the foot brake pedal with your left foot.

14) Immediately after the engine speed becomes steady, record the reading of the secondary pressure (line pressure), engine speed and actual secondary pressure on Subaru Select Monitor. And then release the accelerator pedal. Shift the select lever to "N" range. Let the engine idle for one minute or more to cool it down.

NOTE:

15) Remove the ST and install the plug after measurement.

NOTE: Use new O-rings.
