What Does CAN Mean in OBD2?

CAN stands for Controller Area Network. It’s a communication protocol used by the vehicle’s various electronic control units (ECUs) to communicate with each other and with the OBD2 scanner. This allows for faster and more efficient data transfer compared to older OBD systems. Knowing this helps you understand why the “CAN” designation is important in a modern OBD2 scanner.

Common Uses of a Cen Tech CAN OBD2 Scanner

Troubleshooting with a Cen Tech CAN OBD2 Scanner

Sometimes, a DTC might seem misleading. For example, a code indicating a faulty oxygen sensor might actually be caused by a vacuum leak. This is where a little automotive knowledge comes in handy. Cross-referencing DTCs with online resources or repair manuals can help you pinpoint the root cause of the problem.

How to Read Cen Tech OBD2 Codes?

Once you’ve connected the scanner and retrieved the codes, you’ll need to interpret them. Each code consists of a letter and four numbers. The letter indicates the system affected (e.g., P for powertrain, B for body, C for chassis, U for network). The numbers provide more specific information about the fault.
