No start, 4 codes flashing, stuck in reverse

[4strokerforlife]

2015 Rtx Dx ...last three of the vin are 359...unloaded out of trailer month ago...turned key to start today...reverse alarm on...'R' in the gauge cluster...codes...P0031, P1685,P1689,P1692...pulled battery and put a fresh charge...pulled the reverse actuator and tried to normal the position...couldn't get any movement...any suggestions? Thanks

P0031 is heater controll circuit low
P1685 main relay open circuit
P1689 reverse relay circuit low
P1692 forward circuit low
I'd suspect possibly low or dead battery and or furosemide relays. Maybe someone that has experienced a simarlar problem will chime in, but try checking battery and relays meanwhile.

My early 2015 R-TX-DX came with a bad battery. Started fine in fall, but as it got colder would only turn over but would not start. Diagnostic charger indicated bad cell. Dealer tested found bad, warranty replacement so far no issues, but no snow either so only 277mi on the battery.

I suspected a battery issue first thing...brought battery in and put it on charge...12.6...stuck it back in...same issues...I do have a later production DX as well...vin 394 ...I will try the battery from that one...thanks for the input

Holy cow thats alot of codes! I wonder if the main harness at ECU is plugged in right? Figure it out?

Any updates on whatyou found?
Did you look close at the reverse actuator?
I broke 1 before, bottom of actuator blew out. All the parts were in the belly pan/ footwell. Wondering if yours did the same.

Swapped out the battery with my later production viper...still same issues...actuator looks as it should...checked connections throughout... Still under warranty...headed to the dealer...let ya know what we find out...thanks for the input

Check your fuses ISC blown will cause those codes to pop

 

[4strokerforlife]

Well...the ISC was the cause...after further investigation... The terminal wasnt installed correctly in the fuse block...allowing the terminal to not be clipped in the block...once turned 180° it locked in and the 15 amp ISC fuse was properly plugged in...how the sled went 700 miles with the fuse and terminal not having very good contact being loose is crazy

Thanks for update. Good thing to remember.

So this exact same thing happened to men today. Hit a road approach a little hot and after what in my mind was an extraordinary long time in the air, I landed flat.

Sled turned off and would not restart. Reverse alarm beeping, wouldn’t start, dead with all the codes and a few more flashing.

Eventually, growl, I checked the ICS FUSE. Yup. Changed and all good.

What does that fuse control and why would it have blown from a jump?

Thanks Grizztracks, thats what I thought it controlled but curious why it would blow from a landing. Any insights?

 

[grizztracks]

Not really sure. maybe a wire got pinched. If it keeps doing it you'll need to inspect the harness for damage to one of those circuits.
