July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

12-Volt Power Down

NOTE:

Because the high-voltage battery is used to charge the 12-volt battery via the power inverter module (PIM), disconnecting the 12-volt battery negative cable alone will not power down the 12-volt system. The following procedure must be carried out before any repairs, disassembly, or testing requiring 12-volt power down are carried out.

NOTE:

Even though the high-voltage battery manual service disconnect is removed during the 12-volt Power Down procedure, the 12-volt Power Down procedure will NOT safely and reliably power down the high-voltage system. If any high-voltage components are to be accessed, disconnected or tested, the High-Voltage Power Down procedure must first be carried out. Refer to ELECTRIC VEHICLE CONTROL SYSTEM, STANDARD PROCEDURE .

  1. Turn the ignition to the OFF position, and wait five minutes to allow the high-voltage system to shut down without setting a fault code.
