Code B2610 2015 GMC Sierra Description

The instrument panel dimmer switch is used to increase and decrease the brightness of the interior backlighting components. The dimmer switch provides a voltage signal to the Body Control Module (BCM) that will increase as the brightness of the lights is increased and decrease as the brightness of the lights is decreased. The BCM provides a low reference, signal, and B+ voltage reference circuits to the dimmer switch. When the dimmer switch is placed in the desired position, the dimmed voltage setting is applied from the dimmer switch through the dimmer switch signal circuit to the BCM. The BCM interprets the signal and applies a Pulse Width Modulated (PWM) voltage through the Light Emitting Diode (LED) dimming control circuits illuminating the interior backlighting to the requested level of brightness. The Diagnostic Trouble Code (DTC) sets when the BCM detects a problem in the LED backlight dimming control 1 circuit.
