SERVICE ACTION: BATTERY MANAGEMENT SYSTEM
(BMS) LOGIC IMPROVEMENT (SA302)

 NOTICE
Inform the customer that the BMS update will reset the adaptive learning values to
default conditions. As a result, the displayed range/DTE (Distance to Empty) and
charge times may be temporarily increased. It does not affect the actual range or
battery charging time. These displayed values will gradually be relearned to reflect
the actual battery condition with multiple drive and charge cycles performed above
50°F (10°C) from less than 20% SOC to more than 90% SOC.
Important: If the customer has any range concerns, please see PS548 and capture all
BMS data BEFORE applying the update.

ECU Upgrade Procedure:
To correct this condition, the ECU should be reprogrammed using the KDS
download, as described in this bulletin.
