LI-ION BATTERY JUNCTION BOX DATA CLEAR

Description

Perform Li-ion Battery Junction Box Data Clear when the Li-ion Battery Junction Box is replaced with a new one. VCM counts the times system main relay is turned off due to a large current and use this information to manage the system main relay deterioration status. As the system main relay deterioration status progresses, a DTC "P31DE" is detected and notification that the Li-ion battery junction box needs to be replaced is given.
When the Li-ion Battery Junction Box is replaced with a new one, there is a difference between the System
Main Relay cutoff count stored in VCM and the actual System Main Relay cutoff count. In this case, VCM will detect the DTC with incorrect timing. So perform Li-ion Battery Junction Box Data Clear to clear the System
Main Relay cutoff count stored in VCM.
