Dash warning lights

[majfrizz]

Have an 2018 Tiffin Bus with 450 cummins engine on Powerglide. Drove about an hour this morning and was getting ready to get on interstate. These two flashlights came on. I have reset the battery, turned engine on n off a few times, still there. Waiting for call back from tech support at Saferide roadside assistance. Cummins dealers closed around here today. Any thoughts

If those lights are on with the engine running shut it down or it will do it for you.
Typically Amber lights can go on and off as you drive but you can't drive on red.

Check your coolant level in the reservoir and not the radiator, they have a sensor in them that if the coolant levels get too low it will throw a stop engine light like you have there.

Low oil pressure will do the same so check for low oil levels.

Check for a broken or missing belt on the engine.

Thats the first things I would check before I called anybody.

Don't try to drive it with a stop engine light on.

Thanks for the response. All levels and belts look good. Have plenty DEF. Talked to road service and they said tow it to Cummins dealer.

Check for error codes. They will give an indication of what may be triggering the lights. Codes can be accessed by simultaneously pushing both buttons on speedometer then going down to status.

Thanks for letting me know how to get the codes. Powerglide is new to us, have always had a freightliner. Here is the code on the dash. The tech came out to the coach with his computer and it is showing a 1922 Cummins code. Basically, the high pressure is clogged and not regenerating. Now I have to wait for a bay to open.
