Cat® SIS2GO

I have a 1985 Peterbilt 359 with a Cat 3406B and it has greatly helped me in repairing that engine. It has a bunch of useful information. Troubleshooting guides, torque specs, step by step repair instructions, parts lists and diagrams. Truly a great and convenient tool for people working on their own equipment.

It is great when it works last two days all I get is a black screen no information multi billion dollar company or to be able to fix the app

For some reason I can’t download truck engine service information. I used to be able to with previous versions but now I can’t. Download starts and immediately goes white screen and app crashes.
