212: Say That Louder For The Module In The Back
About this episode
A detailed diagnostic journey on a 2009 Chevy Suburban reveals the complexities of GM CAN bus communication issues. The host shares a challenging case involving a non-communicative fuel pump control module, highlighting the importance of thorough network scans, verifying power feeds, and understanding network topology. The culprit turned out to be a corroded fuse and an open network segment affecting communication, which was mitigated by adding a terminating resistor. This episode emphasizes learning from diagnostic struggles and the nuances of GM module programming and CAN bus troubleshooting.
Today on the show I share a case study on a 2009 Chevrolet Suburban that has no communication with the fuel pump control module. Simple right? Well it should be, but I spun my tires on this diag and wanted to share with everyone why, so you can avoid the same mistakes!
