TCM Learning

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.

In the following case, TCM learning is required.

1)	Automatic transaxle assembly replacement

2)	TCM replacement

3)	TCM upgrade

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.

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)
