Let’s face it, we’ve all been there. You’re looking at a used car, and you’re wondering if the odometer reading is accurate. Maybe you’ve even heard stories about people rolling back their odometers to inflate the value of their car. But can you really trust the odometer reading you get from an OBD device?
Understanding the Importance of the Question
This question is crucial for several reasons:
- Automotive Repair Professionals: Understanding the limitations of OBD devices is vital for accurate diagnostics and repairs. A mechanic needs to know whether they can trust the odometer reading or if they need to seek additional information.
- Vehicle Owners: Knowing how to verify odometer readings is crucial for making informed decisions about buying, selling, or maintaining a car.
- Legal and Regulatory Compliance: In many countries, manipulating odometer readings is illegal. Understanding how odometer readings are stored and accessed helps ensure compliance with regulations.
The Short Answer: It’s Complicated
The answer to the question “Can PCM odometer reading be found with an OBD device?” is not always straightforward. While some OBD devices can access the odometer reading stored in the Powertrain Control Module (PCM), this is not universally true.
Here’s why:
- OBD Protocol Variations: Different car manufacturers use different variations of the OBD protocol. Some manufacturers restrict access to certain data points, including the odometer reading.
- Car Model and Year: Older car models may not have the same level of connectivity or data availability as newer models.
- OBD Device Capabilities: Not all OBD devices are created equal. Some devices are more advanced and can access more data points than others.
So How Can You Verify Odometer Readings?
Here are some alternative methods to verify odometer readings:
- Car Service History: Check the car’s service history for evidence of regular maintenance, which can give you an idea of the car’s actual mileage.
- Vehicle Inspection: A professional vehicle inspection can provide a more comprehensive assessment of the car’s condition, including the odometer reading.
- VIN Check: You can use a VIN check service to get a detailed history report of the car, including its odometer readings from various sources.
