1. Select "All Tests and Calibrations".

4. Then, select the “Transmission Learning”.
5. Perform the N range learning according to the 

directions on the screen.

shift the selector lever to the P position and 
turn the ignition switch to the LOCK position, 
then to the ON position after 5 s.

• If “Reinstall TCM properly and then try again” is displayed, perform the following inspection:

— Verify that the transaxle manual shaft is in the N position.

• If the manual shaft is in a position other than N, shaft it to the N position.

— Verify that the selector cable is adjusted properly.

• If the selector cable is not adjusted properly, adjust it. (See 05-18-7 SELECTOR CABLE 

ADJUSTMENT.)

— Inspect the manual shaft lever for deformation.

• If there is any malfunction, replace the manual shaft lever.

6. Shift the selector lever from P position to D range, then verify that the positions of the selector lever and the 

indicator are aligned.

• If there is any malfunction, inspect the DTC. (See 05-02-5 DTC TABLE[AW6A-EL, AW6AX-EL].)
