Stall Test: Inspection

Purposes of the stall test:

• Operational check of forward clutch and reverse brake
• Operational check of the torque converter assembly
• Engine performance check

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. Refer to SUBARU SELECT MONITOR EN(H4SO) (diag)-34, 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. Refer to , ADJUSTMENT , CVTF.
7. Increase the CVT temperature to 60 to 80°C (140 to 176°F) 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:

    • Do not perform a stall test for over 5 seconds at a time. (from closed throttle, fully open throttle to stall speed reading.) Failure to follow this instruction will cause the engine oil and CVTF to deteriorate and the clutch and brake to be adversely affected.
    • Be sure to cool down the engine for at least one minute after each stall test with the select lever set in the "P" or "N" range and with the idle speed of 1, 200 RPM or less.
    • If the stall speed is higher than the specified range, attempt to finish the stall test in as short a time as possible, in order to prevent the CVT from sustaining damage.

    Stall speed standard: 

    2, 400 - 3, 100 RPM
