power train control module (PCM) with on-board diagnostics (OBD II)
- PCM with OBD II was developed to accommodate the goals of achieving mandated emissions control and improving vehicle performance
- The latest PCM incorporates more functions, more memory and more new integrated circuits than the former control system, helping it be more precise than its predecessors PCM features and benefits:
- Potential improvements in:– Performance– Drive ability– Fuel economy– Emissions control
- Through state-of-the-art technologies, Ford Service Technicians are able to fully reprogram the PCM memory by electronically “talking” to a single connector on the vehicle, allowing the module to receive upgrades rather than requiring replacement
- PCM system enables Ford vehicles to comply with the latest California Air Resources Board (CARB) OBD II requirements designed to help maintain vehicle emissions control. As more stringent emissions regulations are adopted in the future, the PCM will be able to adapt to these as well PCM enables Ford to meet OBD II requirements by monitoring:
- Catalyst efficiency
- Fuel system
- Evaporative emissions
- Exhaust gas recirculation
- Other emissions-related control systems as well as various sensors and actuators The PCM also helps improve accuracy during repair procedures. The PCM’s enhanced capability expands the ability of Ford Service Technicians to trace problems, even intermittent problems, quickly and easily.
- Through the use of diagnostic scan tools, Technicians also are able to retrieve recorded vehicle performance history from PCM, leading to quicker and more accurate diagnoses.
