Need a Caterpillar Comm3 Adapter - Martin56 - 10-18-2024
I urgently need a replacement for my Cat Caterpillar ET Diagnostic Adapter III, which broke during diagnostics between my Cat ET and Perkins engine. Here are the issues I’m facing:
- Error Message with Cat ET: Error #142 (adapter not plugged in)
- Error Message with Perkins EST: Error #142, even after changing the cable
- Device Manager Issue: Unable to read the adapter
I am looking to buy a new or used Comm3 adapter. Does anyone have one for sale or know where I can purchase one? Any help would be greatly appreciated. New or used is fine—I need it urgently!
Thank you!
