TCM Learning

When shift shock is occurred or parts related with the transaxle are replaced, TCM learning should be performed.

In the following case, TCM learning is required.

Transaxle assembly replacement
TCM replacement
TCM upgrading

Scheme 133

TCM learning condition ATF temperature: 40 ~ 100°C (104 ~ 212°F)
TCM learning procedure Stop learning Repeat the below shift pattern four times or more with stepping on the brake. Driving learning Drive the vehicle through all gears at D range. Drive from stop to 1st to 2nd to 3rd to 4th to 5th to 6th with keeping fixed throttle open. Down shift from 6th to 5th, 5th to 4th, 4th to 3rd, 3rd to 2nd, 2nd to 1st. Repeat the above driving pattern four times or more. Up-shift throttle open: 15 ~ 25%

Make sure vehicle does not roll before setting room side shift lever and T/M side manual control lever to "N" position.
Remove the battery and the battery tray. (Refer to " «CHARGING SYSTEM»(ref-536081) " in EE group.)
Remove the air cleaner assembly. (Refer to " «INTAKE MANIFOLD»(ref-536078-S21176328432013031400000) " in EM group.)
Remove the shift cable mounting nut (B). Tightening torque: 7.8 ~ 11.8 N.m (0.8 ~ 1.2 Kgf.m, 5.7 ~ 8.6 lb-ft)
Disconnect the inhibitor switch connector (A).
Remove the manual control lever (B) and the washer after removing a nut (A). CAUTION: When installing, affix the manual control lever and the inhibitor switch with ø5mm (0.1969in.). Then tighten the inhibitor assembly mounting bolts.
Remove the inhibitor assembly (A) after removing the bolts (2ea). Tightening torque: 9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft) CAUTION: When installing, tighten the inhibitor assembly mounting bolt lightly, so that necessary adjustments can be made. Tighten to specifications.

Checking List Of Shift Lock

Brake pedal being not depressed. AT lever (shift lever) must not be shifted from "P" position to "R" position.
Brake pedal being not depressed. AT lever (shift lever) must not be shifted from "N" position to "R" posion.
Brake pedal being depressed by stroke 15-26mm in "P" position. Push button can be operated and AT lever (shift lever) can be shifted smoothly from each position to other positions.
Brake pedal must be operated smoothly without interruption at all positions.
