6. How We Test Best OBD2 Tools
How do we test the best OBD2 scanners?
To test OBD2 scanners, we connect each scanner to a vehicle’s OBD-II port and verify that it can report the car’s vehicle identification number (VIN). We then monitor the engine and other vital systems, disconnect the engine’s oil temperature sensor, and check the details provided by the scanner.
6.1 Wireless Scanners
How do we test wireless OBD2 scanners?
For wireless scanners, we connect to an Apple iPad Pro, Microsoft Surface, or Samsung Galaxy S9+ phone via Bluetooth or Wi-Fi. We measure the wireless range and monitor the engine and other vital systems.
6.2 Handheld Scanners
How do we test handheld OBD2 scanners?
Handheld scanners are plugged directly into the OBD-II port, which provides power. We measure the cord’s length and monitor the engine and other vital systems.
6.3 Performance Data
What performance data do we monitor during testing?
We monitor engine speed, timing, coolant temperature, and other key parameters to evaluate the scanner’s ability to display operating data accurately.
6.4 Fault Codes
How do we verify the accuracy of fault codes?
We disconnect the engine’s oil temperature sensor, check the details provided by the scanner, fix the problem, turn off the check engine light, and erase the error code.
7. Deciphering Fault Codes
What are the components of a fault code?
All fault codes have four numbers and a letter prefix: Powertrain (P), Body (B), Chassis (C), Undefined (U). The numeric section starts with a 0 for generic codes and a 1 for manufacturer-specific codes.
7.1 Generic vs. Manufacturer-Specific Codes
What is the difference between generic and manufacturer-specific codes?
Generic codes apply to all cars and are the same across different makes and models. Manufacturer-specific codes are unique to individual carmakers and represent either a special piece of hardware or a more in-depth analysis of the problem.
