Restore Your 4WD System with a Plug-and-Play Solution
Real-World Repair Story
I remember a customer with a 2011 Tahoe who was about to leave on a family camping trip. The day before, his ‘Service 4WD’ light came on, and the selector switch went dead. He was panicked, thinking his transfer case was shot, facing a multi-thousand-dollar repair. After a quick scan, I found a U0102 code—Lost Communication with TCCM. The module, located under the driver’s side dash, had failed internally. Instead of a complex repair, we installed one of these VIN-programmed modules. In under 30 minutes, the light was off, the 4WD system was shifting perfectly, and he was able to leave for his trip on time. It’s a perfect example of how the right part can turn a potential disaster into a minor hiccup.
