Jcb Servicemaster
The diagnostic tool downloads data from the vehicle's onboard diagnostic port, providing information about vehicle problems. Make sure that the diagnostic tool properly fits, and start the engine to monitor the condition of your car or truck. If your vehicle stores the code in memory, there is no need to start the engine. Start the Diagnostic Tool. Some scanners will automatically begin reading the code, while in some, you'll need to give a scan to start the process. After scanning, it will display the trouble codes read. If not, note down the code. For effective fault diagnosis, refer to JCB Servicemaster diagnostic software.
