Priority Group B

• IHKA fan (except during defrosting)
• Rear IHKA fan (only for E66)

Priority A systems are dependent on battery SoC (State of Charge) and generator output during the operation of the consumer.

Priority B systems are only dependent on the battery SoC.

The Power Module also sends out a telegram indicating the status of the Load-circuit peak reduction function. The priority level of the message is classified by a number 0 through 6.

• 0 = Normal operation without peak reduction (KL 15 "ON")
• 1 = Terminal R "ON" without peak reduction OR  generator defect or under-voltage acknowledged.
• 4 = Corresponds to maximum peak reduction.
• 5 = Corresponds to medium peak reduction.
• 6 = Corresponds to minimum peak reduction.

The computation by the Power Module to determine which priority level is necessary is based on the battery SoC. Example: the threshold for priority level 6 is a 65% SoC.

Current vehicle priority levels can be displayed in the Diagnosis Program.
