GM-50332-335 allows the GM-50332 Battery Depowering Service Tool to be electrically connected to the Bolt EV battery pack high-voltage circuit at the RESS battery pack BDU connector to allow depowering of the pack through that connector if vehicle circumstances do not allow access to the other high-voltage connectors for depowering. The cable is also used to check for voltage with a DVOM at the RESS BDU connector to ensure the pack is fully depowered before the technician begins any disassembly and service procedures.
