Rostra cruise control issue - Toyota Yaris Forums

Shroomster · 05-22-2010, 01:16 PM

I need help with where to begin. The dealer installed rostra cruise kit shuts off intermittently and sometimes but not always, on bumps in the road. Dealer could'nt reproduce concern, obviously. Anyone, maybe CTScott lol, have any ideas on where to start? Im gonna look first at the. Connector ends to ensure they're tight. after that dunno what to check. Thanks in advance!!

90% odds that its a loose connector somewhere.

If the dealer installed it, they should fix it.

If dealers actually cared about warranty work then it wouldn't be a problem....I'm trying to get the wife to let me take it in and get someone to drive it with me on the interstate, but she is closed-minded about giving up her car for more than a few hours let alone a day or so....

at any rate I actually was hoping someone might have the diagram handy of the wiring diagram for it.....if not I will check the company site for a possiblity....

I have a problem with the brake pedal stop light switch being too sensitive/ill adjusted, so when going over bumps, the brake lights turn on intermittently. That also turns off the cc when hitting bumps. You can drive at night and put a piece of paper in the rear window to make it easier to tell if your brake lights are on when they shouldn't be.

I fixed it by jammig a double sided piece of scotch tape on the tip of the stop light switch.

Along the same idea, if yours is manual, check the tightness of the clutch switch. Since it is happening on bumps, it may be due to those pedals moving aRound sensitive switches.
