TCM Learning
- Overview and purpose of learning
- The purpose is to ensure the initial operation safety by correcting the oil pressure differences between transmissions.
- 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.
- In the following case, TCM learning is required.
- Automatic transaxle assembly replacement
- TCM replacement
- TCM upgrade
- TCM learning procedure
- Condition: ATF temperature 35 - 95°C (95 - 203°F)
- Stop learning
- Repeat the shift pattern shown below five times or more with the brake stepped on.
- 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 - 2500 RPM of engine)
- 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.
