Both statements are correct. Digital temperature gauges often use bar-type displays where the number of bars increases or decreases based on the temperature reading from the sending unit. Additionally, some warning lights in vehicles are indeed triggered by the Powertrain Control Module (PCM) or the Body Control Module (BCM), as these modules monitor various vehicle systems and can activate warning lights when issues are detected.
