Cruise control DOA

[fasterdammit]

My first thought is that, after 200k, the CC's Set/Resume contacts have simply had it, because there's nothing else that jumps out as wrong. But I just wanted to ask the question & see what y'all thought:

I have a (new-to-me) '00 SR5, just shy of 200k on the clock. I just had the shop go through the truck because I had both the ABS and Check Engine lights on (w/ different circumstances) - they're fixed, but still I have no Cruise. The Cruise light comes on when I hit the button, but it will never engage. The fuses are ok and there's no check engine light or any other telltale signs that something's amiss.

So I'm stumped, except to think that maybe the switch itself has had it. Can anybody point me in direction to check things out? Wiring harness, sensors, ECUs?

Thanks in advance!

Make sure the brake lights work.

Make sure the brake lights work.

While I haven't confirmed this myself, I have to assume they must since it just passed inspection (NYS) 3 weeks ago. And no one's rear-ended me in 500 miles ...

Local Toyota tech says cruise won't necessarily throw a code if it's not working, too. ugh ...

I used to live in ny, I wouldn't assume that.
I've seen them with all the brake lights burned out, and I've seen the stop light switch fail.
Either will cause the cruise to not work.
Besides that, there's the spiral cable, the switches, wiring, etc etc.

Turns out it was a busted wire, and apparently a common problem. Haven't seen the wire they were referring to, but it had to be cheaper than $1500 for a new brain.
