Code B3596 2014 Chevrolet Silverado Description

The hazard flashers may be activated in any power mode. The hazard warning switch signal circuit is momentarily grounded when the hazard warning switch is pressed. The Body Control Module (BCM) responds to the hazard warning switch signal input by supplying battery voltage to all four turn signal lamps in an ON and OFF duty cycle. When the hazard warning switch is activated, the BCM sends a serial data message to the instrument cluster requesting both turn signal indicators to be cycled ON and OFF. The Diagnostic Trouble Code (DTC) sets when the BCM detects a short to ground in the hazard warning switch signal circuit.
