light failure sensing + pictogram question Posted by vtsnaab [Email] (#26) [Profile/Gallery] (more from vtsnaab) on Sat, 28 May 2011 05:22:24 Members do not see ads below this line. - Help Keep This Site Online - Signup |
My '94 Aero has always given me fits with the high-mount brake light; a single bulb looses contact and the pictogram comes on to tell me about it.
I mess with it - it comes back on - the display goes off.
(Repeat weekly...woof.)
I've also added some very nice LED substitute bulbs (which do a very good job BTW) and the light failure sensing is having a fit.
Yes - I know it is possible to add loading resistors - thereby wasting power and 'fooling' the silly sensor - and I *don't* want that for my car, thanks.
(The high-mount is NOT LEDs and it needs no resistors either !)
My question:
Short of pulling the dash-top and instruments and rooting out the pictogram's bulbs for lamp failure - is there a quicker/easier way to lobotomize this unappreciated dysfunction ?
(I should have yanked those when I killed the stoooopid 'shift up' one and so on...but I forgot to.)
The schematic seems to show that it is a function of the main lighting relay (at least for the front), and obviously I cannot pull that !
Thanks.
