Scrolling through your vids and seeing the tablet. 95% sure your likely a lead Penske tech. Reasons from the tablet, and info on all major engines and apu stuff even. Am I wrong?
Is this the Detroit diagnostic link and can you adjust the cruise control coasting and engine brake engagement speeds? For example I bought a 2019 Freightliner dd15 without the radar on the bumper or windshield but it has a parameter set so when I set the cruise control at say 65 mph it will Coast it down to 60 mph and then engages and goes back up to 65 mph. And then the engine brake doesn't come on until 5 mph over the Cruise speed setting. Is there a way to adjust that?
Yes it is Detroit diagnostic link and yes you should be able to adjust those parameters. However if you engine computers are password protected you’ll need the passwords to change speed settings and a few others
As long as it is the same part number. Like if you were to have the same module from a different truck that is the same you could, but not if it is a different part number. As far as I know.
Do you mean what do you use to connect your computer with the detroit software on it to your truck? If that is what you’re asking, normally I would use the nexiq usb link. It is a little blue box that has one cord that connects to your computer and another cord that connects to your truck.
I keep having the same code pop on every 400 miles 3058 9 and sometimes 10 I done change every sensor that’s required to change for that code new delta pressure pipe sensor somebody please help
