I was running a wire through the 2007 LX470 firewall today via the driver's side engine bay grommet, into the cab above the brake pedal.
After starting the truck I noticed the brake light on the dash is solid on. I suspect I nicked a wire somehow but I'm not sure how I can verify that's the case vs. an actual brake problem (and I know how suddenly brake failures can happen in these rigs)
Any ideas on how I can differentiate between something like a failed emergency brake switch, master cylinder problem, or nicked wire in the harness (or some other reason the light is on)?
One other very odd thing: Because the light was on I played a bit with the brake pedal. If I'm parked and pump it hard about 15 times in a row, the brake warning buzzer comes on with a bunch of lights: vsc, vgrs, abs, and maint reqd. Then after a few seconds it all quiets down and goes back to normal. Not sure if that's new because I hadn't ever done that before.
