I have a 2003 Honda Accord EX V6. Recently, the Traction Control System (TCS) light on the dash has been coming on, but upon turning off and restarting the car, it disappears. This has been happening on and off.

I went to my Honda dealer's service department and they did a diagnostic test on the TCS and told me that the computer said I needed a brake light switch.

I thought a brake light switch was the switch that turns on the brake lights... what does that have to do with the TCS light on my dash?

Thanks.

I have no idea either... but I am having that same problem and I'm about to replace mine as well... at least it'll fix the problem... hopefully!
