My Dyna did this after towing a trailer with suspect brakelight wiring. Try checking the 7.5A fuse labelled ICU-IG & replace if nessesary (after assuring yourself the fuse labelled STOP is still intact). Mine blew both fuses twice before I sussed it so it's most likely that this is your issue also & is a simple fix. If it's not those 2 fuses & that's quite unlikely, you'll then probably need to replace the electrically controlled vacuum actuator on exhaust pipe. Good luck- Enjoy:)
switch at foot pedal perhaps?
every toyota does its usually found in the trunk or sometimes found in the tires connected to the main wiring harness next to the exhaust pipes
Bad bulbs can be the cause of your reverse lights not working on your 1999 Toyota Tacoma. A problem with the reverse switch or bad wires can also be the cause of your reverse lights not working.
Check the bulbs, the fuse and the brake light switch.
A malfunctioning brake light relay switch will cause your 1993 Toyota Corolla brake lights to stay on all the time. The brake light relay switch is located beneath the drivers side dashboard.
Possible bad switch on the brake pedal? When you push on the brake pedal, it activates a switch, that switch turns on your brake lights. If the bulbs and fuses are ok, check the switch with an ohmeter.
It is the brakes light switch
