    Cat 299d2 scr issue

    Got some new info. On my snapon pro-link ultra I can see some live data. The one I’m watching is labeled AFT 1 temperature sensor 2 and With key on engine off it will show a message of data valid but below normal operational range- most severe. With the machine running at idle the message...

    Back working on this machine. Still having the same issue. Throwing one single code and going into limp mode. Anybody have a diagram or picture of where the AFT 1 temperature sensor 2 is located on this machine?

    Cat 299d XHP

    I’m on step 3. I feel like I’m doing something wrong. When I go to test resistance from j2-34 to the other ones I’m not getting anything. On any of them. I’m suppose to be checking j2-34 to.. j1-13…j1-23…j2-33 right? If so I’m not getting anything on any of them. I did pull the jumper wire out...

    Cat 299 speed sensors

    I’m not fully understanding what it’s asking me to do on this one.. I get I need to measure the resistance. But what does it mean when it says measure it to all contacts of the harness…. Like one probe on j2-35 and the other probe I just starting touching all the other pins 1 by 1? D. At...

    Cat 299 speed sensors

    Yes they are active. I pulled the codes through the monitor In the cab. As far as what it’s doing, you can be driving along and out of nowhere it will pull left or right. It will kind of alternate sometimes it’ll jerk to the left, sometimes the right. Kinda just starting acting up out of...
