Power Lumbar With Cushion and Backrest Massage

Each front seat functions independently of each other. The lumbar control module is located in the seat backrest. The system will function only with the engine running. The lumbar control module does not report DTCs and does not communicate on the CAN. The button pushed on the seat control switch will determine what function the module will carry out. When an individual circuit is switched to voltage, the lumbar control module will carry out a function.

The pump supplies air pressure through a hose to the lumbar control module. The module then directs the air through multiple hoses to the appropriate cushion or backrest pillow.

Refer to SEATING  in this service information for switch and system operation.
