Remote start working intermittently

[Jreiter2]

I have a 2020 Ram 1500 eco diesel with about 18k miles. Recently when I try to remote start the truck the horn beeps twice and the lights flash but the truck doesn’t start. I tried this with my second Fob which I’ve never used and got the same results. All of the other functions on the remote work fine. Any thoughts to what the problem can be? Thanks.

So, not an FCA vehicle but our Honda Odyssey does similar stuff. If I unlock the van, then lock it back then try to remote start it typically acts proper after that. Maybe give it a whirl?

are you low on gas? are you sure the truck is locked?

if you are low on gas the truck will not remote start. typically you'll get a message on the dash when you get in though.

Edit: i see you have the diesel.... I meant low on fuel** lol

Haven’t tried to unlock then lock the truck. I’ll try that and see what happens. This is something that has changed in the last week or so. I have plenty of fuel. I’m scheduled for oil change at the dealership next Tuesday. I’ll ask them to look at it since I’m still under warranty. Thanks for the suggestions.

There's another thread on this forum somewhere talking about this and it seems to occur more frequently with the diesels (at least in that thread).

When you push the remote start button twice, the truck locks the doors, then it starts the truck.

My truck did what the OP's truck is doing, one time. I didn't have the driver's door closed all of the way, so it couldn't lock the doors. There are a number of things like doors and hood being closed, etc that your truck checks before it can perform a remote start. Maybe one of those items is interrupting the process.

Is there an error message in your instrument cluster after the failed remote start? Do you have an OBD II scanner that you can use to check faults?

Remote doesn't work? And it's winter? And cold? Huh. Never heard of this happening before..... Strange.

There's an update flash for the ecodiesels to fix it. Mine did the same thing. The problem is the voltage is sensed as being too low and it won't start. I had the update done last week and it's worked everytime since.

I know you're referring to this thread, but they might be different issues.

Anyway, check this thread...it might help.

Remote start not working when cold

Hey, As the title states, if I attempt to remote start when the truck is cold it will honk once and the do nothing. There are no error messages either... It has ample amount of fuel, engine light isn't on, and doors are closed. If I manually start the truck, let it run, shut it off, the...
