4. AWD FUNCTION
If ªtight-corner brakingº occurs when the steering
wheel is fully turned at low speed:
1) Determine the applicable trouble code and
check the corresponding duty solenoid C (transfer)
for improper operation.
2) If the solenoid is operating properly, check
transfer clutch pressure.
3) If oil pressure is normal but ªtight-corner brak-
ingº occurs:
Check the transfer control valve for sticking, and
the transfer clutch facing for wear. [W20B0].> and
7. Stall Test
A: MEASUREMENT
1. GENERAL INFORMATION
The stall test is of extreme importance in diagnos-
ing the condition of the automatic transmission and
the engine. It should be conducted to measure the
engine stall speeds in R and 2 ranges.
Purposes of the stall test:
1) To check the operation of the automatic trans-
mission clutch.
2) To check the operation of the torque converter
clutch.
3) To check engine performance.
2. TEST METHODS
1) Preparations before test:
(1) Check that throttle valve opens fully.
(2) Check that engine oil level is correct.
(3) Check that coolant level is correct.
(4) Check that ATF level is correct.
(5) Check that differential gear oil level is cor-
rect.
(6) Increase ATF temperature to 50 to 80ÉC
(122 to 176ÉF) by idling the engine for approxi-
mately 30 minutes (with select lever set to ªNº
or ªPº).
2) Install an engine tachometer at a location vis-
ible from the driver's compartment and mark the
