SYMPTOM TROUBLESHOOTING [AW6A-EL, AW6AX-EL]
STEP
• Is stall speed normal?
5
(See 05-17-3 MECHANICAL SYSTEM
TEST[AW6A-EL, AW6AX-EL].)
• Stop the engine.
6
• Inspect following solenoids.
(See 05-17-20 SOLENOID VALVE
INSPECTION[AW6A-EL, AW6AX-EL].)
— Line pressure control solenoid
— Shift solenoid C
— Shift solenoid E
• Are they normal?
• Verify test results.
7
— If normal, return to the diagnostic index to service any additional symptoms.
— If malfunction remains, inspect the related Service Bulletins and/or On-line Repair Information and perform
repair or diagnosis.
• If the vehicle is repaired, troubleshooting completed.
• If the vehicle is not repaired or additional diagnostic information is not available, replace the TCM.
Initial Learning
Warning
• When performing initial learning, be aware of other vehicles, people, and other impediments in
order to avoid an accident.
Note
• While self-learning control gradually reduces shock during normal driving, initial learning is performed to
initially learn a certain amount of driving conditions.
1. Warm-up
• Increase the ATF temperature by leaving the vehicle idling or performing city driving. Verify that the ATF
temperature is between 66— 110 °C {151— 230 °F}. If the ATF temperature is outside this range, work to
bring it inside the range.
Caution
• Do not raise the ATF temperature by stalling the engine.
Note
• If the ATF temperature is not between 66— 110 °C {151— 230 °F}, initial learning cannot be performed.
Before learning, inspect for variable shift shock.
2. Garage shift learning
• With the vehicle standing still, depress the brake pedal and keep the selector lever in N position for 3 s.
Then, shift the selector lever from the N position into D range, and maintain in this condition for 3 s. Repeat
this procedure 5 times. Then repeat it 5 times in the same way for R position.
3. Gear shift control learning
• In D range, with the accelerator opening between 25— 30%, drive until you reach 6th gear and a vehicle
speed of 80 km/h {50 mph} or higher. Then, release the accelerator pedal and coast, and bring the vehicle
to a stop in at least 60 s. Repeat this procedure 10 times.
4. Inspect learning results
• Verify that variable speed shock and shift shock have decreased compared to the conditions before
learning.

INSPECTION
Yes Go to the next step.
No Repair or replace any malfunctioning parts according to the
inspection results.
Yes Inspect the ATF condition.
• If a large amount of metal specks are found, replace the
transaxle.
(See 05-17-29 AUTOMATIC TRANSAXLE REMOVAL/
INSTALLATION[AW6A-EL, AW6AX-EL].)
• If a large amount of metal specks are not found, replace
the control valve body.
(See 05-17-38 CONTROL VALVE BODY REMOVAL/
INSTALLATION[AW6A-EL, AW6AX-EL].)
• Replace the control valve body.
No
