Subaru Crosstrek Service Manual: Time lag test Inspection
CONTINUOUSLY VARIABLE TRANSMISSION(TR580) > Time Lag Test
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.
• Perform the test at normal operation CVTF temperature of 60 — 80°C (140 — 176°F).
• Be sure to allow one minute or more interval between tests.
• Make three measurements and take the average value.
1. Apply the 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:
1.5 seconds or less
If “N” > “D” time lag is longer than specified:
• Secondary pressure (line pressure) is too low.
• Forward clutch worn
• Forward clutch piston malfunction
• Control valve body malfunction
• Learning incomplete
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) is too low.
• Reverse brake worn
• Reverse brake piston malfunction
• Control valve body malfunction
• Learning incomplete
