2015 Coronado - No Speedo or cruise control

One would think that if the ECM is still seeing Road speed then the issue would be the body controller, because that drives the gauges, IIRC?

 

Not a cpc, but maybe a samchassis.

The OP stated this is a Coronado that is a glider. The Coronado is a 122 SD and does not have a SAMCHASSIS nor SAMCAB. It would have a PDM to support body controlled features with many "analog" type of switches and such.

I would need the last 6 of the VIN to verify what the intended powertrain was with this thing. Then I could look at the intended speedometer. OP says the lightbar was replaced, I then suspect this might have an ICU4M and then leads me to think the wiring of the satellite gauges.

 

Odometer inop? You really need it hooked to a laptop, and verify road speed, and check switch stats to see that the ECM is getting the signal from the cruise switch.

But, you mention no data through the 9 pin IIRC? That could be the root cause of all of it

Spitballin here, but check the 2 wire plug that comes off the vehicle harness and runs to a cab connector towards the starter. Just make sure ut's connected

 

So yes, this has the ICU4M. It has been known that the daisy-chain pins go bad on the jumper harness. The female pins lose their tension and can cause issues like these.

BTW, it looks like you have a DDEC III (maybe DDEC IV) intended engine in this glider.

Here is the P/N of the jumper harness from the lightbar to various sat gauges (maybe try getting a new one of these):



Inspect the back of your speedometer and also the jumper harness:






A for cruise control, you do have a clutch-switch as well as two buttons related to cruise request. I would check to make sure that the clutch switch is correctly toggling. This is really challenging because you have a glider.
