Backed too far into boat launch

[Ramboh]

Went to a different ramp than usual and it was not steep enough to get the boat to float off the bunks so i had to back in pretty far and i believe something got wet that shouldnt of. Says traction control is off and ESC is off and i have no 4wd. What is in the rear that shouldn't of gotten wet? Wheel speed sensor?

I don't know about ESC, but I get that light occasionally when driving in the rain and through puddles. If you find out, please let me know. In my case, the next day when I start the ESC light is out.

did you try a battery disconnect reset?

I find a good brake check will get the boat off the bunks in shallow ramps.

i have not yet, i was going to see if a few days of drying out would correct it.

Very likely that one of your wheel speed sensors got some moisture in it. I would check them out and make sure the connections are good and dry.

Yep. Sounds like a wheel speed sensor signal missing. Could be caused by rust buildup on the face of the sensor.

battery reset did not fix it. Still says service ESC and service trailer brakes.

Can i verify the wheel speed sensors with Alpha OBD?

 

[PurpleRT]

If it was me….
Unplug them, spray with electronic cleaner, allow them some time to dry out, disconnect the battery while you wait. Reconnect plugs, reconnect battery then go for a short drive.

 

[Ramboh]

I only found a couple of faults while browsing through Alpha OBD.

 

[GMetal]

How far did you go in? Check connectors that could have been submerged. They should all be sealed but there's a chance for a improperly assembled connector that got wet. Also check the diff for water. There's a vent that could let in water if you went too deep.

 

[Ramboh]

i really didnt go that far just more than i usually do. it was just at the exhaust tips and about half the rear wheel. I really dont see much that would of been submerged besides the wheel speed sensors and the parking brake solenoids (Maybe).

 

[Limited Legend]

Sounds like it could be a failing wheel speed sensor perhaps.

The ZR13 code reader from Harbor Freight will scan wheel speed sensors. Not sure about alpha.

alfa OBD will give you live data with the ability to record the output of the sensors.

I assume you've already seen this thread as well...

2019 Ram 1500 (3 Errors - Service 4WD, Service ESC, Service Trailer Brakes)

Just had these three pop up while driving on the freeway. Truck has the Maximum Care Extended Warranty (Just hit 60k miles). Anyone every have all 3 of these pop up at once? Its going to the dealer once I call them on Monday. As luck has it, this happened after 5pm on a Saturday.

Yes i was able to verify all 4 wheel sensors on alpha lastnight. I did find a blown Fuse on the interior panel F01 30Amp for the Trailer receptacle. Replaced it and still Getting Service ESC, Service 4wd, service Trailer brake system.

This is from another old thread way back:

Ask your dealer to check the 4wd actuator plug/connection. It sits right below the oil filter and if the filter is tipped over when changing it out, oil can run into that harness and into the plug and cause electrical issues. Might just need to spray it out with brake cleaner and be on your way.

Have AlfaOBD look specifically at the ABS module, this is the guy that this likely tripping the warning lights.
