On the last waveform photo you uploaded I'm wondering if the places where the signals go high & low momentarily are when data transmissions are occuring. Have you tried adjusting the horizontal axis knob to zero in on these? Also, I took a look at your scope manual and it talks about a...

Documentation on the devices communication format would be helpful. These things may not transmit anything until they recieve a command or request from another device.

Recessive state is when the bus is idle meaning no devices are transmitting messages. All devices on the CAN bus monitor the state of the bus and will only transmit if they detect a recessive state. This is to prevent data collisions from more than one device transmitting at the same time...

Congratulations on your newly acquired skill of using a scope. Yeah that waveform looks like it has some flat edges but not what data should look like. Have you tried probing the scopes test point to see if you get a nice square wave? Also, where did you connect the probe & ground to take...

Yeah, take a module home, power it up and work there. Progress will improve greatly I believe. Don't let the scope intimidate you with all of the switches & knobs, they're really quite simple to use. It's just a voltmeter that shows you what the voltage is over a period of time rather than a...

Perhaps putting 24V on a pulled module and bench testing it in the comfort of your home would be easier than on a 5-ton until you establish communications?

I would get a scope on the data lines to see if anything is happening electrically before investing further effort. If square waves are in fact there then you'll know there is data to be read. I'm not familar with whatever programming language the code you posted is written in, however I've...

DE = DRIVER ENABLE, pull high to enable data transmit RE = RECIEVE ENABLE, pull low to enable data recieve. These pins are commonly tied together so that a single signal control circuit can enable either mode by placing a high or low on the line. You could permanently wire DE to high and RE to...

Dry...lol...

UPDATE: Finally got the inside blasted and in primer. This exposed some holes, poor drywall mud like patchwork, and thinning that I couldn't tell was there under so many layers of paint. The good news is the ceiling is not as bad as I thought it was. Next step is to start patching the area's...

Are you sure all of the batteries were completely charged before operating the truck? Completely charged means more than a 12V reading with a meter. It means able to pass a load test. My guess is the generator issue was no coincidence. These generators are only rated for 60A which is...

Perhaps a "What broke on your 5-ton this week?" thread is in order?

Fuse panel is a good guess, however there isn't one lol. There are a few (5?) fuses hidden here and there but I'm confident that is not the problem. There is no fuse for seperate lighting functions. All of the exterior lights are powered from the same supply through the light switch. The...

According to the wiring diagram the trailer tail/marker lights are fed from the same pin and wiring as the tail/marker lights on the truck so I am dumbfounded as well. Perhaps there has been some re-wiring somewhere in the truck? Or trailer???. I suggest separating the trailer from the truck...

The goofy problems with these trucks never ceases to amaze me! According to the wiring diagram the tail/marker lights are fed from the light switch. Try disconnecting the light switch and jumping a wire from pin F(+24V) to pin H(tail/marker lights) on the harness connector. When the battery...

When the parking brake is released an electrical switch should apply GND to wire 584/PIN I on the failsafe module causing the flashing parking brake lamp and buzzer to stop. I'm guessing the switch is not connected or working correctly(open circuit).

When it is not building pressure, remove the large air line(output) at the compressor unloader valve. Is any air pressure being produced? If no then remove the small control air line at the compressor unloader valve. Is any air pressure being produced now? If not then the unloader valve is...

I heard Uranus smells like crap and is even worse during the hot summer months.

The truck is a big hit with the kids as expected.
