ADAPTATION
In order to compensate for the manufacturing tolerance, an initial adaptation for the clutch is required after:
a reflash of TCU software
replacement of TCU, or
a replacement of the transmission.
The CVT check light flashes once every 2 seconds if the initial adaptation is not performed*.
This can be realized by performing multiple shifts between the tramsmission positions during ilding.
Adaptation can be performed without additional equipments.
CONDITIONS
Throughout the procedure
Vehicle being stationary
Accelerator pedal is not applied
Stable engine indling speed
Stable and warmed-up CVT fluid temperature
Foot brake is applied
PROCEDURE
warm up the engine and transmission
shift to Neutral (N) position for ≥ 5 seconds
shift to Drive (D) position for ≥ 5 seconds
shift to Neutral (N) position for ≥ 5 seconds
shift to Reverse ® position for ≥ 5 seconds
repeat 2 to 5 for 20 times* (apply foot brake thoughout this stage)
shift to Drive position
gradually accelerate to >50km/h
gradually stop the vehicle
complete
*if only the transmission is replaced, the CVT check light wouldn't flash, hence the need to repeat the shifting 20 times to make sure that the adaptation is completed. If the CVT check light is flashing, the procedure can be stopped once the CVT check light has stopped flashing and turned off.
UPDATE #1: it has also been reported that a long period power disruption to the system may cause the TCU to loose the adaptation data, hence the need to readapt it before the vehicle is driven. This is to prevent unnecesary wear in the transmission and certain drivability issue due to poor clutch engagement especially for vehicle with high mileage
Oh mai...Adaptation need to do by ourselves In order to compensate for the manufacturing tolerance, an initial adaptation for the clutch is required after:
