According to the display on the GTS, select "Step 4 Learning" and then "Next" to perform external backup boost converter (eco run vehicle converter assembly) existence learning.

HINT:: ·

If the external backup boost converter (eco run vehicle converter assembly) existence value of the old engine stop and start ECU differs from the current learned value or if data could not be downloaded from the old engine stop and start ECU, the learning result will be displayed.

·

If the external backup boost converter (eco run vehicle converter assembly) existence value of the old engine stop and start ECU was "available" but the value after replacement is "not available", the external backup boost converter (eco run vehicle converter assembly) may not be connected securely. Check the connector connection condition and perform learning again.
