Hyundai Palisade: Automatic Transaxle Control System / Repair procedures
TCM Learning
1. |
Overview and purpose of learning
1) |
The purpose is to ensure the initial operation safety by correcting
the oil pressure differences between transmissions.
|
2) |
For relearning of TCM, process relearning by deleting existing
contents using diagnostic tool when there is shift shock at
gears 1-2-3-4-5-6-7-8.

2. |
In the following case, TCM learning is required.
1) |
Automatic transaxle assembly replacement

3. |
TCM learning procedure
1) |
Condition : ATF temperature 35 - 95°C (95 - 203°F)
|
2) |
Stop learning
- Repeat the shift pattern shown below five times or more with
the brake stepped on.

3) |
Driving relearn
- Maintain the throttle open to a constant level with the gear
in D position and increment from 1st to 5th gear within 1500
~ 2500 RPM of engine and decelerate slowly.
With (ON, throttle opening: 0%), decrement from 8th to 1st gear.
- Upshift throttle opening : 15 - 35% (a proper value for making
upshift within 1500 - 2500RPM of engine)
