2003 prius, red ! warning light, no cruise control, reverse
2003 black toyota prius -- similar problem.
Today, at noon-ish, pulled into our bank (5 miles from house). Daughter got out of rear door, and I noticed that the warning light came on.
Stayed in car, wife and daughter went in, etc. -- car kept turned on.
Went home, called maplewood toyota. They said to turn it on & off 5 to six times to turn off the light. 4 times did it. Told to keep driving it.
Drove about 20 miles, went into a store -- 25 minutes -- then came out.
Warning light came on, no reverse. (in parking lot, needed to back out)
Would go forwards. Neutral, pushed it out. Drove home, noticed that there was no cruise control. At home, reverse had started working again.
Warning light will NOT go out this time. Going to take it in tomorrow, as the dealer closed at 5:30pm, and it was rush hour and 5pm ... and normally it takes 20 minutes to get there ... .
(This is our second prius. silver 2002 totaled in 6 car pileup last may.)
[so, what are the common components between the 2003 and 2004!??]
Update 4/26/2004. Took it in. They could only find that the brake fluid level was down a bit. They claim that when any sensor goes off, all kinds of things go flaky.
How do we connect to the computer? Serial cable? USB? I have a serial break-out box someplace ... pointers?
Update 7/18/2004 -- Any fluid level going low does this triangle warning light business. Last time we took it in to be serviced (15k) the owners book seems to have disappeared -- or we misplaced it. Anyway, put fluid in windshield washer, brakes, tranny, radiator, etc, etc. Then do the on and off three or four times to see if it goes off. If not, try looking for something else that would be obvious. Nothing like a car that knows what is wrong, has a huge screen where it could draw pictures and point at the thing that is complaining ... yet just puts out a non-descript red !. Just as good as those old computer compilers that found an error and printed out ? and nothing else.
