I replaced the battery in my wife's 07 RDX last night.

Today she left for work and called me freaking out saying that the transmission light is on as well as an error code (P0847 I think).

Also, the radio wont work and says enter code.

I am sure this is a result of the system resetting, but how can I fix it?

Thanks

 

Why is she crazy?

If my SO touched my car and my transmission light / error code popped up I'd freak out too..

The radio code can be found in the users manual on a card or stickied on the side of your glovebox or battery tray. It should be a 5 digit code.

In regards to the transmission code..

Try unplugging the neg terminal and see if it comes back. The specific code is to the 3rd gear pressure switch. Make sure you didn't unseat the connection when you swapped the battery.. Worst case you spend $40 and replace the switch / sensor.

i don't know about the rdx, but the tl's radio code is stamped inside the glovebox. when you open the glovebox, its on the left hand side.

 

Part #12 is the 3rd gear pressure switch / sensor. It would be right below the battery tray. You might need to remove the plastic guard beneath the case to get to it.
