Lumbar Supports
The lumbar support system is a strap system that tightens and loosens to give support to the driver's or passenger's back. Battery positive voltage (B+) is applied at all times through the RH rear junction block PWR STS circuit breaker via CKT 1340 ORN) to the lumbar switch. When the lumbar switch is operated, battery positive voltage (B+) is applied to the lumbar motor to move the lumbar strap into or away from the driver's or passenger's back by loosening and tightening the strap.
