What a great forum, after having faults appear on the dash I done some research replaced the brake switch and all seems well after 1 weeks driving......great !

Thats what we are all here for. Great news, welcome to the site.

Hello, I am having the same problem with my 2006 RRS. I was having problems with my battery a few months back so I got it replaced. About a month into my new battery the three warning lights in your title started popping up but would go away after turning the truck off then on. Two weeks ago the lights stay on constantly now. I too have spent hours researching a fix to this and have changed my tail bulbs to OEM since I had aftermarkets I installed months back, replaced the parking brake switch hard reset the car for remove codes and still nothing. I was wondering if the warning lights disappeared as soon as you changed the switch or any further action had to be taken? Looking forward to your reply!

Thanks in advance!

Check the upper tailgate switch. They can corrode and cause a big battery drain. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

Hi there, I actually changed out the brake pedal switch and not the parking brake switch. All the warning lights have never come on since and all has been well since,
Hope this helps
