GM Class 2 Network Diagnosis Tips

Automotive network communication diagnosis can be overwhelming for some technicians. With videos like this, we hope to help tie up some loose ends you may have to help increase your efficiency and accuracy as a diagnostic technician. In this video, Keith demonstrates how to properly identify which module has caused complete network failure on this 2003 Chevrolet Trailblazer. By utilizing a convenient splice comb built into the vehicle, and single channel U-scope purchased from Aeswave.com , Keith was able to quickly identify which direction to travel next by isolating the module causing the network to be compromised. We thank you for watching and hope you enjoy!
