B1315 Code - Backlighting Non Reflective Controls Illumination Output Circuit Short
Quick Answer
When the parking lamps are on, the Body Control Module (BCM) provides voltage to the hardwired dimmable illumination sources based on the Steering Column Control Module (SCCM) illumination messages sent to the BCM over the network. Common causes include Faulty Body Control Module (BCM), Body Control Module (BCM) harness is open or shorted, Body Control Module (BCM) circuit poor electrical connection. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.
