Good evening Acurazine. I recently came across a DTC while driving 2007 TL Type-S with some friends earlier today. I will make this post as detailed as possible to explain what is going on, because I can't seem to find any other thread regarding this DTC except for a few Honda Pilot posts.
I was driving back from eating with friends, and a car had turned into my lane while I was driving about 40mph, I had to abruptly brake. Then I accelerate back to normal. My VSA indicator comes on. So I stop by a gas station to fill up on gas and turn my car on and off. However upon starting the car, I cannot get the vehicle out of the "park" position. So I managed to set my e-brake, unlock the PRDNL using the the unlock next to the shifter, disengage the e-brake and allowed me to put it in drive and head home. My first guess would be the brake switch, as when I applied the brake, my brake lights nor my third brake light would not turn on at all. I did see that in the navi system diag., DTC 68 indicates brake pedal failure. I've attached a picture of the DTC itself. Since the brake pedal switch is the least intrusive to diagnosis, I removed it and tested continuity. It seemed just fine with continuity when pressed and depressed. So now I'm at a loss here. I also tested the battery with NO LOAD, and got 14.5 volts. I'm still somewhat confused to why this is happening. Some other users who came across this DTC had battery issues, but on Honda Pilots, which I believe is not the case with mine. I have a feeling that the braking from earlier tonight may have had something to do with it. What would be my next steps in figuring out what can fix this issue?

I'm also being told that resetting the VSA might fix this, as it is possible that the VSA module's computer might be confused? However I'm not sure on my vehicle's "resetting" procedure.
If your brake lights didn't light up you have power issues. No matter what, I would start with replacing the brake switch. The VSA module has no play in the illumination of the brake lights as far as I know.

I had to have it locally ordered for pickup next day at the dealership since they were not available. I'm usually okay with waiting a few days for parts for delivery, but seeing that this is also a safety issue when driving at night, I had to spend a little extra to have it by tomorrow morning. I will update once I get the switch and replaced.
I didn't have any codes being thrown on mine, but my wife had told me she could barely see my brake lights during the day. All of my brake lights "worked" but were extremely dim. My tail lights were just fine. A quick stop at the local Honda dealer to pick up a switch and about 10 minutes to swap it out, and back to wickedly bright brake lights.
Different issue than you, but my point being the switch can be "failing" while still technically testing ok.
sounds like a fuse may be busted causing some of your issues. Check the fuses and that should fix the locked shifter. Also check your brake fluid level! Lastly, check and see if you a/c is dripping water under the car when running and it's not backing up and draining out in the center console under the radio/behind the cubbies DIRECTLY ONTO THE PCM/ECM/ECU!!!!!!
UPDATE: I went ahead and changed the brake switch, which has not fixed the DTC unfortunately. The brake lights still do not illuminate nor do they appear "dim". I am now suspecting that this might be an issue with brake fluid level, or possibly a ground or power fault issue. I noticed that the troubleshooting pages were posted above. Thank you so much posting! I do not have my car at the moment, but I will start the troubleshooting process in the morning. Firstly I will check brake level fluid, and then continue the steps from there.
EDIT: I have already done the brake pedal switch and adjustment, but I have not been able to clear the code atm.

I did notice that at both times that I attempted to press and depress the switch, the rear brake lights do not illuminate at all, nor were they dim. What fuses should I be checking for those circuits? Both under the dashboard and under the driver-side cabin?
UPDATE: I borrowed a friend's service manual for looking up wiring diagrams for the STOP/brakelight and taillights system, and began to start with the power source of the brake light. I found out that the horn circuit was also tied in with the same power source for the brake lights.Using the diagram, I found that No.13 (20A) fuse in the under hood/relay box controls the stop and horn circuit. I checked for continuity between the fuse, and received an O.L. I remove the fuse and found that it was blown. I did recall that I had braked and used the horn at the same time, so using both at the same time for a few seconds could have overloaded the fuse, causing it to blow. My issue is now resolved!
One note that I may add with this: DTC 68 for the VSA seems that it can be one or two things, the fuse which controls the power to the brake lights, or the brake switch has legitimately gone bad. First replacing the switch did not resolve my problem until I had checked the power for the brake lights. So before replacing the switch, ensure power is being delivered to the brake lights, otherwise this specific DTC may throw you off thinking it is the actual brake switch.
