I’ve got a 2016 Kia Sportage 1.6T GDI and I’m facing an issue with all the dash lights coming on. I don’t have an OBD scanner and there’s no rear camera installed (though I’ve seen some mention this could cause it). I’ve disconnected the front ABS and tried a few other things, but it’s still happening. Anyone have an idea what could be wrong?
Check your battery and the gas cap. Many cars will act up if the battery is low. Also, if it’s been cold lately, the battery could be too cold to work properly. If the battery and gas cap seem fine, head over to an autoparts store, they usually offer free scans for your car.

The battery is charged and the alternator’s fine. The car won’t allow me to scan it since it says no modules found.

That’s odd. Next thing to try would be checking your fuses. If the OBD scanner can’t find any modules, something’s not connecting right.
@Meryann
The problem here is that the OBD reader is telling him there are no modules, so the reader is getting power. It’s not likely just a fuse issue—more likely the CAN bus or ECU has a problem.
It could be that the battery is low and there’s not enough power for the sensors. Another possibility is that something got unplugged. If you can, try doing an emergency brake check in a safe area to see if the ABS system is working. If it’s not, something may be unplugged. I had a similar issue with my Kia Cee’d ED after changing the clutch.
Looking at the RPM, it seems like the car is off and in accessory mode. Just to clarify, do the lights stay on when the car is running? Or is it only in accessory mode that they appear?

The car is working, but I don’t have a speedometer or RPM showing up on the dash.
The car works and drives fine, but the dash lights stay on like that all the time.

Have you had any crashes or bumped into anything recently?

No, nothing like that.
You might want to try resetting it at a Kia service center. They have the software to do that. If the problem doesn’t go away, it could be worse. Last year, I had a similar issue and they told me a pump was broken, which would’ve cost me €3000 to fix. But honestly, you just need to erase the errors and check the sensors around your brakes.
It could be a loose connection at the camera. Try unplugging it and then plugging it back in to see if the issue clears up.
Oops
When you turn the key and don’t start the car, all the lights will come on. Try starting the car and see which lights stay on.

The car is working though…

I figured it does. Just making sure!
This could be a CAN communication issue. Try removing the fuse for the backup camera. I’ve had issues before where the backup camera causes a CAN Bus failure, bringing down communication with other modules. If that doesn’t help, start pulling fuses in the interior fuse panel and see if a module is causing the problem. If your car has a turbo engine, check the vacuum pump—it’s another common part that can mess with the CAN bus.
@Gordon
I’ll check that. Thanks for the tip .
Having all the lights on like that usually points to a CAN fault, especially since the tachometer is showing zero. You also mentioned the OBD scanner can’t find any modules, which fits with that theory. Unfortunately, this might require a professional to diagnose.
