Iquad coolant Gauge 204 F to -40 F

[G_Fass]

Having an issue on my iQuad gauges, when the coolant temp hits 205F it jumps to -40F instead, gauge on the dash still works fine,   Is there a way to pull a CAN rip off the adrenaline to check the values when the coolant temp switches from 204F to 205F?

Limitation of the CANBus. Nothing can be done about it. Cluster runs on the CCD network.

Yup, it kinda sucks, but it just reminds me to look to the cluster when I see -40.

Yep,  send a big o'le thank you to dodge / cummins for deciding that anything over 204*f on the j1939 network is not important.    

 

 

spent more time than I care to admit trying to fix this, but the data is just not there.

Thanks Guys,

 

Good to know.   I wish there was a J1939 standard that they could have designed to.  If only SAE would have come out with a list of J1939 standards for all engine/automotive companies to follow

lol, there was a j1939 standard at that point,  even SAE standard.  They just didn't follow it back then.  OEM was just given a lot of room to do what they want

 

for example.

 

the coolant is read via the stardard, offset / size / pgn etc etc.   They just for whatever reason don't report anything over 204*f.  

 

 

same goes for ALOT of things on the bus.  IE: True engine load, there kinda there on 98-00, but not really...  but 01-02 engine load is reported correctly.  

 

 

Baro: always reports 14psi....... no matter what truck

I had just assumed G_Fass was being sarcastic in his post. Because, come on Dodge, its right there. Why limit it?
