Understanding OBD2 and PCM
Before diving into free scanner programs, let’s clarify the basics of OBD2 and PCM. OBD2, or On-Board Diagnostics II, is a standardized system that allows external devices to access a vehicle’s diagnostic data. The PCM, or Powertrain Control Module, is the brain of your car’s engine management system. It constantly monitors various sensors and actuators to ensure optimal engine performance and emissions control. When a problem arises, the PCM stores a DTC, which can be retrieved using an OBD2 scanner.
