HellRaiser1st 1 Report post Posted February 3, 2018 Hi, I own a gt86 for a year and a half now and i had no problems with it until 2 moths ago. I went to the dealer to get some new tires as they had an offer 3 tires + 1 free i parked the car went inside, ordered the tires the mechanic came to move the car and the car would not start. everything was working battery power to fuel pump dash, headlight... just the starter would not kick in. they had it in the shop for 2 months now and cant figure it out apparently my ecu and remote entry ecu fuse keeps blowing, resulting in frying my original ones. They replaced mine under warranty but it keeps happening again when they tested it. Toyota Mechanics believe its a short circuit on one of the wires on the main harness but i doubt it. the only electrical modification related that i done to the car are the fog-light bulbs, i replaced them with LED bulbs same size same dimensions same shape as OEM but LED. Has anyone on this forum ever had or heard of any similar problems on the 86? if so can you give me some pointers as im a bit annoyed now for 2 months they couldn't find it and they are puzzled as to what is causing this issue Share this post Link to post Share on other sites
Lauren 2259 Report post Posted February 3, 2018 It's no help, but I've honestly never heard of this problem with these cars. Share this post Link to post Share on other sites
HellRaiser1st 1 Report post Posted February 3, 2018 i know, toyota is puzzled as well. I heard of some frs cars in the US having problems similar after installing led fog lights but toyota keeps saying its on a different circuit the ecu and foglights... so i don't know what to make of it, warranty will cover it but i miss my car 2 months now have past Share this post Link to post Share on other sites
Lauren 2259 Report post Posted February 3, 2018 I cannot see how changing the fog light bulbs for LED's could have any effect whatsoever. Maybe put them back to stock? You never use foglights anyway IME. Reckon I've used them about three or four times in five years. Share this post Link to post Share on other sites
HellRaiser1st 1 Report post Posted February 3, 2018 i used them a lot as i mostly drive at night and i never use the high beam as my eyes adjust easier to oncoming traffic lights if i stay on low beam and foglights instead of high beam. also the oem ones were quite yellow the led ones are as white as the headlights so it looks better as well. i've seen some people having problems with the clutch sensor, but that still does not explain the ecu fuse blowing every time. 1 Test Drives Unlimited reacted to this Share this post Link to post Share on other sites
Lauren 2259 Report post Posted February 3, 2018 The problem is, having front foglights on just blinds oncoming traffic and does nothing to help you see really. I would say you make the problem worse for oncoming traffic if you have fitted even brighter foglights. Share this post Link to post Share on other sites
surrey86 352 Report post Posted February 3, 2018 Sounds like a case of foglight karma. Seriously, sounds like you need them to get a decent automotive electrician to look at it. Share this post Link to post Share on other sites
Kodename47 446 Report post Posted February 4, 2018 Why not take the bulbs off and see what happens? Getting the bubs in/out is a 10 min job, then if the fuses stop blowing you know it's the fogs. If it's the only thing that's been changes then it's the 1st place I'd be looking to prove. 3 Lauren, Church and GT86-Ian reacted to this Share this post Link to post Share on other sites
