GGRG 0 Posted March 10 Share Posted March 10 Hi. Apologies if the answer is somewhere on the site already but I am failing to find it. Does anyone know if the wiring on a 2010 Yaris is CANBUS or not? I want to wire a piezo beeper into each rear light so that I can hear if the indicator has not auto cancelled and I have failed to notice the light flashing, which is not in line of site. Also anecdotally someone mentioned to me that Toyota produced a bleeper that is more audible and can be retrofitted. Does anyone know of this? Quote Link to post Share on other sites

flash22 751 Posted March 10 Share Posted March 10 Why the rear lights ? an easier point would be the hazard switch, be aware that the stalk is a negative switch I'm not sure if anyone makes a flasher relay with sounder for the Mk2 Yaris Quote Link to post Share on other sites
GGRG 0 Posted March 10 Author Share Posted March 10 Thanks. I'll put this idea to my electrician friend. I did try to get the covers off behind the wheel. Gave up. Very hard to get them back too. No CANBUS? Quote Link to post Share on other sites
flash22 751 Posted March 11 Share Posted March 11 It looks like its BCM controlled, all you need is 1 sounder, 2 diodes and a bit of wire if the indicators flash fast/slow it may need resistor(s) as a ballast p90 hazard.pdf 1 Quote Link to post Share on other sites
