Learning Overview and Purpose
- It aims to correct the deviation between transaxle products to reduce learning time and secure initial driving safety.
- When gear shift shock has occurred at the 1-2-3-4-5-6 positions, delete the previous learning values using diagnostic tool device and perform TCM learning again.
Conditions that Require Learning
- After replacing automatic transaxle
- After replacing TCM
- After performing TCM reprogramming

TCM Learning Method

Learning with the vehicle stopped

While pressing and holding the brake (vehicle is stationery), set the throttle opening to 0% and repeat the following procedure four times.

Learning with the vehicle running
- Maintain a consistent throttle opening at the D position and gradually shift from 1st gear position to 6th gear position one by one. Then, gradually shift from 6th gear position to 1st gear position one by one (brake: on, throttle opening: 0%).
- Throttle opening (for shifting to upper gear): 10 - 50% (less than 5% of throttle opening (APS) change)
- Repeat the above procedure four times.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.

• Brakes feel soft, pull hard to one side, or make grinding noises.

• The engine overheats, stalls repeatedly, or misfires under load.

• You are missing required tools, torque specs, or safe lifting equipment.

• You are not confident in the next step or safety outcome.
