CAN BUS Diagnostics: We are seeing a rise in communication type problems and U codes. Diagnosing CAN Bus faults can be a challenge. The service manual techniques leave a lot to be desired and if the BUS is not communicating with your scan tool you can not rely on codes to help you out. This class looks at how to use the lab scope and proven techniques to trouble CAN Bus failures. We will look at the different types of Bus failures and how to approach diagnosing a Bus failure. We will use a series of case studies to highlight different techniques.
