Interior right turn signal lights up when braking or accel

jlwhite · 06-13-2005, 09:32 PM

Just wondering if anyone else has seen this in their Prii?

When braking or accelerating hard the interior right turn signal on dash gets brighter. The car has always done this since I've owned it and I haven't got it checked out yet by Toyota. Anyone else?

Thanks,

Get it checked. This is odd.

Why not? your over half way thru your warranty and it's done this since new. I'd have been back on day two and probably yelling at someone.

Good point. I just thought it might be a quirk with a new model year vehicle etc and I'd get the run-around by Toyota service. If nobody else has seen this then I'm taking it in ASAP. Thanks!

I assume you mean braking before engaging in a turn? Otherwise, why would the turn signal be on at all?

Nope. Braking or accelerating at any time (without turning) lights up the right interior turn signal on dash only (slightly) (I don't think it affects the actual exterior turn signal and its fairly dim, i.e. during the day its hard to see but at night you can see it rather clearly - its a little distracting actually).

I'm going into the dealership at noon to get the ball rolling on this one.

Thanks and I'll let you know what comes of it. Cheers!

OK, took a look at the wiring diagram. The turn signal monitor on the combination meter gets its power from the same source the outside lamps get them: from the flasher relay.
Sounds like you have a bad ground or possibly a burned bulb. That would explain braking, but not so much for acceleration.

Turn on your hazards and check that all bulbs light. Check that all other lamps in the combination lamp assembly in the rear work.

Thanks DanMan2, I'll check it out!

DanMan32...Just a follow up....I checked all lights as you said and everything checks out fine. I've scheduled an appointment for next week at my dealership so I'll update from there. Should be a real treat :x Thanks for the help!

hey i had a car that did that. the right turn signal came on anytime i hit the brakes. it didnt blink or anything. which is kinda funny since one of the brake lights didnt come on when this happened (only happened about 80% of the time)

is it a problem? was for me. the reason it was happening was because of inherited rear end damage that caused intermittent ground problems, which in turn, caused a whole host of electrical peculiarities.

my advise... well you really dont need any.
