Alarm + VSC TRAC, TRAC OFF, ABS, Emergency Brake Light On

10

Asked by Dec 18, 2017 at 01:11 PM about the 2004 Toyota 4Runner

Question type: Maintenance & Repair

The other day, about 10 seconds after starting my 2004 Toyota 4Runner SU
with a little over 181,000 miles on it, the VSC Track, Trac Off, ABS and
Emergency Brake light all came on, as well as a continuous alarm sound
(emitted primarily from the left-hand side of the steering wheel).

Turning the car off and back on did not help. Took it for a test drive to see how
it handled, and after about 15 minutes I noticed the brake pad locking up. I
had to press down hard on it for the car to slow down.

I turned the car off for about 2 minutes, started it again, and the alarm and all
those lights came back on, but after about 15 seconds it all stopped; the
alarm, the lights, and the brake was working just fine.

This has happened on two occasions, with about 5 days in between each
event.

My local mechanic says it might be the ABS or PCM system failing.

As a side note, my check tire pressure and "MAINT" light have been on for a
few weeks now as well, but we've had a cold weather spell and I haven't had a
chance to check the tires, and I just recently had an oil change and assume
they just failed to reset the "MAINT" gage. However, I wanted to mention this
in case it's related to the issue with the alarm, brakes and other lights coming
on...

Any thoughts and/or ideas on this is greatly appreciated!

Thanks!

check your brake fluid if low all those lights will come on, but not the tire monitor light.

Is this still happening?/. Just happened to my husband this AM. All the lights and the siren - went for a few minutes then it stopped and seems fine to him. Wondering if you had more repairs? Thanks!

are you entering the vehicle with remote or key?

cjsras: thank you for the tip about the fluid. I haven't checked it yet, but we haven't had this happened anymore... also, we have both the remote and key, and the two times it's happened it's been with both. Kens-toyota: it has been about 2 weeks since it has happened, so hopefully it were 2 isolated incidents. I was told by two private mechanic shops and a Toyota dealership that it could be isolated occurrences, or a sensor going bad, or the ABS or computer system needing repair. That latter would be the worst case scenario. I'll provide an update should this happen again. I appreciate the responses!
