When the key is inserted into the driver door key cylinder and turned to the Unlock position, a switch within the driver door latch closes causing the voltage to drop within the key switch unlock signal circuit. The Body Control Module will detect the drop in voltage and will command the doors to unlock. The Diagnostic Trouble Code (DTC) will be set when the Body Control Module detects a short to ground on the driver door key switch signal circuit.
