2006 Toyota Highlander - B1241 code?

I'm looking at purchasing a vehicle and took it to our mechanic for a lookover. He said that it pulled a code of B1241 Body #1 ECU Switch, but he didn't know / it didn't tell him what needed to be done to fix it. He said that we would need to take it to a Toyota place for them to tell us what it needs.
I was wondering if anyone here might be able to help.
Vehicle is a 2006 Toyota Highlander. It has a 3.3L V6 engine, with just under 90,000 miles. The check engine light is not on, but the mechanic said that it pulled that code.
Thanks for any help you guys can provide!!

That's a body code for the light switch. It could have been set simply by having the light switch on when checking the BCM for codes. I would have it cleared and see if it comes back or lights any lights. Make sure the light switches work properly.

As far as I know, the only light that we were told was out was a rear brake light. All the inside dome lights were working when we checked them.
So basically, if he had the car door open and the dome lights were on when pulling codes, it could have pulled that one? Or, more likely, it pulled it because a rear brake light is out?

No, I'm referring to the light switches, not the bulbs.

Okay, I think I've understand now. As long as all the light switches (in the steering column to turn on headlights, etc..., right??) work, then the code can just be cleared with nothing needing to be repaired / replaced.
Sorry, I am just wanting to make sure that if we buy the vehicle, we have as little surprises as possible. I don't want to spend a bunch on an SUV, and then have to shell out a ridiculous amount for repairs in addition to it!
Thank you for your help!!

I can't tell you "for sure" anything. I'm just making suggestion. If you want to be sure, have an auto electric shop check it out.
Here is what the manufacturer says about the code.
DTC B1241 Body ECU Switch Circuit Diagnosis
DESCRIPTION
The following explains when this DTC is output:
This DTC is not output when the switches are operated but fail to make contact. It is only output when the switches are stuck or held on. For example, this code is output when checking the DTC while the switches are on:
System is normal:
- DTC is output during DTC check with the switches on.
- DTC is not output during DTC check with the switches off.
Inspect the switches and replace if necessary. If there is no problem with the switches, inspect the wire harness.
