Subaru Crosstrek Service Manual: Road test Inspection
CONTINUOUSLY VARIABLE TRANSMISSION(TR580) > Road Test
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 that the engine speed is 1,100 — 1,400 r/min while driving on the level road at 50 km/h (31 MPH) after accelerating from halting up 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
• Model with manual mode
• Drive in “6th speed of manual mode” [70 — 80 km/h (43 — 50 MPH)], and shift down from 6th to 5th. Check if the indicator of combination meter switches “6” > “5”. At the same time, check the engine brake in 5th gear.
• Drive in “5th speed of manual mode” [60 — 70 km/h (37 — 43 MPH)], and shift down from 5th to 4th. Check if the indicator of combination meter switches “5” > “4”. At the same time, check the engine brake in 4th gear.
• Drive in “4th speed of manual mode” [50 — 60 km/h (31 — 37 MPH)], and shift down from 4th to 3rd. Check if the indicator of combination meter switches “4” > “3”. At the same time, check the engine brake in 3rd gear.
• Drive in “3rd speed of manual mode” [40 — 50 km/h (25 — 31 MPH)], and shift down from 3rd to 2nd. Check if the indicator of combination meter switches “3” > “2”. At the same time, check the engine brake in 2nd gear.
• Drive in “2nd speed of manual mode” [20 — 30 km/h (12 — 19 MPH)], and shift down from 2nd to 1st. Check if the indicator of combination meter switches “2” > “1”. At the same time, check the engine brake in 1st gear.
• Model without manual mode
Drive in D range at [50 — 60 km/h (31 — 37 MPH)], and shift to “L” range. Check if the indicator of combination meter switches “D” > “L”. At the same time, check the engine brake in L range.
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.
