Please, can anyone help? My 2008 Expy EL Limited is displaying, "Park Brake Engaged" in the display center. I have verified that the brake is not engaged. I replaced the Parking Brake Warning switch, and have checked the brake fluid level and verified that there are no leaks. I also checked the brake booster and could not detect any vacuum leaks. Has anyone else ever dealt with this or heard of it? Please help! The only other thing I can think of is the hydraulic pressure switch in the master cylinder.

 

Check the wiring for the switch for a short to ground.
Does the light go out if you disconnect the switch?

 

No the light stays on
So does the red brake light in the instrument cluster. I've had it checked and there were no trouble codes. The technician suggested doing a computer reset.

 

When checking for a short to ground, do I just unplug the switch and touch the end of the plug to a bolt?

 

I am having the same issue. Intermittent warning flashing on and off and sometimes staying on. Checked brake fluid level and replaced the switch. When I replaced the switch, tat seemed to help for awhile, but now it is bad again. Seems strange for an electrical problem to be "kinda" fixed. Any idea where to find a wiring diagram so I can figure out which wire is the ground?
