CELL VOLTAGE HARNESS CHECK

CELL VOLTAGE WIRING HARNESS CHECK

Required Special Tools:

MB991223: Wiring harness set
MB992006: Extra fine probe

1. Check the continuity between the following terminals of the cell voltage wiring harness connecting the cells of the battery modules and BMU. If the check result deviates from the standard value, replace the cell voltage wiring harness.
