Electrical problem

[OEMPlus Raptor]

Check Engine Light (CEL). I went off-road and my horn button stopped working. Dealer found it was a loose connection. Something may have come loose on yours as well.

It sounds like there is an issue affecting the Medium Speed CAN (MS-CAN) bus; all of those systems communicate with each other on that network.

The first thing to check is the tail lamps; look for moisture/water that may have entered them due to damage or being submerged while off road. Water will short the connector pins and pull down network communication. If there are no water intrusion issues, inspect the harness under the rear of the truck. The MS-CAN wires run through that harness to the taillights. Look for trail damage, water intrusion, rodent damage, etc. As others mentioned, you can download ForScan for free and buy a compatible adapter so you can pull codes.

Thank you for your help that was the problem I had water in my tail light I pulled a sensor out dry out the whole tail light and reseal it.

There are a number of possible causes for a Drive Control Malfunction message; you would need to pull DTCs to see what’s going on.
