My son recently took the car off to college and he called to tell me
that when he applies the brake the dash lights come on. He also found
out that at night when turns on the park or headlights, his brake
lights including the factory installed spoiler light (eye level brake
light) is always illuminated. While bringing the car home at night,
he found that the cruise was not working. We tried the cruise during
the day without the lights on and the cruise worked fine. The four
way emergency flashers have no effect on the issue and work properly.
We have talked with several Toyota people and they have gone from the
Main Control Module to a switch in the sterring column. Is there
anyone out there familiar with this problem on this vehicle? Your
help will be greatly appreciated. :?:

I'm not sure what the Toyota people mean by "Main Control Module" as there
are not modules in the car referred to by that nomenclature. If they are
talking about the engine electronic control module, I doubt if that is the
problem because there is no connection with headlights.

The odd combination of problems points to either a bad ground, shorted wire,
or bad combination switch in the steering column.

If you are going tot look for a bad ground or shorted wire, start by looking
at any aftermarket accessories like keyless entry systems, remote starters,
fog lights, audio systems, and Ipod adapters because poor installation of
those accessories is a common cause of odd problems. Check to make sure the
ground wires for the rear lights are making good connection with body
ground. Any body repairs in the area may prevent a good ground.

Also check the wires to the center high mounted stop lamp (CHMSL) on the
spoiler and make sure they are not cut, chafed, or crimped, especially where
it follows the hinge and connects to the wiring harness.

You will need an electrical wiring diagram and a volt/ohm meter to properly
diagnose the combination (headlight, turn signal, and windshield wiper)
switch in the steering column.

Hmmm....I'd be looking at the brake light switch to begin with, and (Good
Luck!) a ground problem.

I think they may be referring to the 'relay integration module', what I
consider to be a horrible abomination, since it contains the buzzer, a
number of relays, the windshield wiper INT timer, etc. So, if one function
goes out, instead of replacing a $7 item, you get to shell out $135 for a
new module!

Not one of my favorite Toyota 'innovations'...

True...but when they do break, it's bad news.

Assuming this all happened at the same time, it smells suspiciously like
a grounding issue. Check the cable from the battery to ground and make
sure BOTH ends are well connected. Second, take another look at the
light switch. It might have failed.

I had a similar problem with my wife's 97, but only on one side.

Ended up being bad solder in the sockets. I took the easy way out and
replaced that cable assembly.

It may be the same idiot worked on both your cable assemblies...
