Manual Verna 5

The document outlines the adaptive learning process for the transaxle control module (TCM) in automatic transaxles, which compensates for mechanical tolerance changes due to wear. It specifies that if battery power is disconnected or a new transaxle is installed, adaptive learning must be restored to maintain shift quality. The procedure involves using a diagnostic tool, ensuring the transmission fluid temperature is above 50°C, and performing specific driving maneuvers to complete the learning process.

AUTOMATIC TRANSAXLE control module ADAPTIVE LEARNING


DESCRIPTION:

The transaxle control module (TCM) has internal logic that allows the TCM to compensate for mechanical tolerance
changeswhich may occur during the life of the transaxle due to normal wear.If battery power is disconnected from
the TCM, the adaptive learningis cancelled.

Whenever battery power is disconnected from the TCM or a new transaxle is installed, follow the procedure below
to restoreadaptive learning:
NOTE
If adaptive learning is not performed, the transaxle shift quality may be affected.

ADAPTIVE LEARNING PROCEDURE:

1. Attach a Hi-Scan Pro and select "Automatic Transaxle" menu, "Current Data" menuand "Trans Temp. Sensor".
2.
Drive the vehicle until the ATF temperature is above50°C or 122°F (adaptive learning does not occur below
this temperature).
3.
Accelerate the vehicle through several 1-2-3-4 upshifts and 4-3-2-1 downshifts at light and medium throttle
openings untilshift flare and shift shock no longer occur.
NOTE
Because of the internal transaxle design, adaptive learning for the 2-3 shift takes longer than the 1-2, or 3-4
shifts.
