Recall Number: 26C10 TRAILER MODULE REPROGRAMMING

[dbbii]

I know this isn''t specifc to Mavericks, but my wife has a Lincoln MKX. It had a recall. Dealer sent out their mobile service. What was supposed to be a 30 minute job turned into an hour. Then, the next time we drove the vehicle we got all kinds of error messages. Called dealer back. Opps. Software update didn't work correctly. We will send a different tech out.

My trailer lights and brake signals quit a month ago. I received the over the air update last weekend and hooked up my trailer to test afterwards. Everything is now working correctly.

Hi. I had the recall fixed also, but my running lights do not work on both trailers. Any thoughts?

So, did you have the recall done “over the air” or when you went into the dealership?
Have to tested the trailers on another vehicle or with a 12 vdc jumper ?
If all that checks good, and only the marker lights do not work then possibly a trailer marker lamp fuse.

Recall was done at the dealer. Same issue on 2 trailers.

Dealer should have checked output of all circuits and trailer brakes, if you have the towing package. Do you have both the flat 4 circuit plug and the RV 7 surcuiyt round plug?
before I took it back to the dealer I would verify that the trailer plugs (both of them) if you have do not have running light output. When the modal cased the problem only the 7 circuit plug was without electricity, the 4 circuit plug worked normally.

Can you clarify this please? When I had the 23C04 recall done on my '23, neither plug had power to the trailer parking/running lights.

My recall was done over the air. The only plug that did not work was the 7 way round plug. All circuits were down or off. The 4 prong plug did not have brake and turn lights but the running lights did work. If I remember the recall stated it affected trailer brakes, turn signals and trailer brake lights only.

Thanks. The recall I had done back in 2023 was definitely a hardware problem, not solvable by a software update.
