TCM TERMINAL INPUT/OUTPUT SIGNAL REFERENCE CHART

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.

  1. Transaxle assembly replacement
  2. TCM replacement
  3. TCM upgrading

Scheme 746

Scheme 746
Scheme 746
  1. TCM learning condition ATF temperature: 60~115°C (140~239°F)
  2. 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. NOTE: Up-shift throttle open : 15~30%
