Functional Assessment
Information
The functional assessment using VAS 6910 - Module balancer must only be performed if there are critical faults for the classifying module stored in the fault memory of the high-voltage battery control unit. If it was not possible to assess the fault memory of the high-voltage battery control unit beforehand, the functional test on the module must be performed using VAS 6910 - Module balancer.
The functional assessment is performed using > 9900 - PIWIS Tester 3 , > VAS 6558A - High-voltage testing module and > VAS 6910 - Module balancer .

If you answered "Yes" to one of the points 12 to 14:
Module status: "Danger"
Alert the fire brigade and take steps to deal with the danger from fire/gas leaks.
If you answered "Yes" to one of the points 15 to 17:
Module status: "Warning"
Store the lithium-ion module in the quarantine location and attach warning signs in accordance with requirements (see "Handling lithium-ion batteries"). Contact Technical Support.
Check the module at regular intervals at least once a day.
