Code P0615 2016 Chevrolet Silverado Description

When the ignition switch is placed in the START position, a discrete signal is supplied to the Body Control Module (BCM) notifying it that the ignition is in the START position. The BCM then sends a message to the Engine Control Module (ECM) that a crank has been requested. The ECM then verifies that the clutch pedal is depressed, or the transmission is in Park/Neutral. If it is, the ECM then supplies 12 V to the control circuit of the starter relay. When this occurs, battery voltage is supplied through the switch of the starter relay to the starter solenoid. The Diagnostic Trouble Code (DTC) will be set when the ECM detects improper voltage on the control circuit of the starter relay.
