Time Lag Test: Notes
This test is to check conditions of clutch, brake and fluid pressure. "Time lag" means time elapsed since select lever is shifted with engine idling till shock is felt.
- Check CVT fluid level.
- With chocks placed before and behind front and rear wheels respectively, depress brake pedal.
- Start engine.
- With stop watch ready, shift select lever from "N" to "D" range and measure time from that moment till shock is felt.
- Similarly measure time lag by shifting select lever from "N" to "R" range.
Gear shifting time lag
"N" → "D": Less than 2.0 sec .
"N" → "R": Less than 3.0 sec .
NOTE:- When repeating this test, be sure to wait at least one minute after select lever is shifted back to "N" range.
- Engine should be warmed up fully for this test.
- Repeat test 3 times and take average of those data for final time lag data.
