Stall Test - Suzuki Liana RH413 Service Manual

Stall Test

This test is to check overall performance of automatic
transaxle and engine by measuring stall speed at "D"
and "R" ranges. Be sure to perform this test only when
transaxle fluid is at normal operating temperature and its
level is between FULL and LOW marks.
CAUTION
!
• Do not run engine at stall more than 5
seconds continuously, or fluid temperature
may rise excessively high.
• After performing stall test, be sure to leave
engine running at idle for longer than 1
minute before another stall test.

Automatic Transmission/Transaxle:
1) Apply parking brake and block wheels.
2) Install tachometer.
3) Start engine with select lever shifted to "P" range.
4) Depress brake pedal fully.
5) Shift select lever to "D" range and depress
accelerator pedal fully while watching tachometer.
Read engine rpm quickly when it has become
constant stall speed is checked.
6) Release accelerator pedal immediately after stall
speed is checked.
7) In the same way, check stall speed in "R" range.
8) Stall speed should be within the following
specification.
Engine stall speed
Standard: 2,200 – 2,600 rpm
