Time Lag Test
S7RS0B5104015
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.
1) With chocks placed before and behind front and rear wheels respectively, depress brake pedal.
2) Start engine.
3) With stop watch ready, shift select lever from “N” to “D” range and measure time from that moment till shock is felt.
4) Similarly measure time lag by shifting select lever from “N” to “R” range.
Gear shifting time lag
“N” → “D”: Less than 0.7 sec.
“N” → “R”: Less than 1.2 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.
