Time Lag Test - Suzuki Liana RH413 Service Manual

5A-34 Automatic Transmission/Transaxle:

Time Lag Test

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.
Troubleshooting

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.
