Subaru Legacy BN/BS (2015-2019) Service Manual: 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 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: • Secondary pressure (line pressure) is too low. • Forward clutch worn • 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 • Piston malfunction • Control valve body malfunction • Learning incomplete |
