Automotive technicians and mechanics often need to access specific information in order to make corrections to an engine or a vehicle’s computer.
Mode 9, one of the 10 modes of automotive scan tools, makes accessing the needed information quick and easy. While applying the information in a practical manner is another story, using Mode 9 to retrieve data is one of the essential tools for any shop.
Mode 9: Display Vehicle Information
Mode 9 is used to retrieve vehicle information, ranging from simple identification numbers to performance counters, vehicle software, and engine data.
The most common use for Mode 9 is simply retrieving the VIN (Vehicle Identification Number). This long set of characters helps identify individual cars and trucks, and while they are usually found somewhere on a vehicle (often on the dashboard where they can be seen through the windshield), having electronic access to the VIN is sometimes necessary.
Another use for Mode 9 is accessing the Calibration Identification (CALID), which is basically the ID for installed software. This information helps a technician know what type of software they are working with. The data is often used in conjunction with Calibration Verification Number (CVN), which is also found through Mode 9. The CVN is used to confirm the integrity and functionality of a vehicle’s software.
Mode 9 can be used to access performance-related information as well. The mode can give reports involving the catalyst, oxygen sensor, evaporative system, and more. It is also helpful in finding information from diesel engines, including NOx reduction, exhaust gas sensor, and pressure control.
Find the Vehicle Information You Need With Mode 9
If you are searching for vehicle information, Mode 9 is your best ally. Drivability issues are often related to a vehicle’s computer programming, and a qualified technician or weekend mechanic can use Mode 9 to access a wealth of data.
Putting the information to practical use may be challenging, but having quick access to VIN, CALID, and CVN data can prove incredibly useful, and it’s all made possible through Mode 9.
