has any one experinced this .........

its like a safetly alert noise when ur over 100km/h coming from behind the dash ......but i have no way of turning it off or on etc .........

is there any way of turning it off? or cuting it out etc?

Ok dude. Where you left knee is. Its up there somewhere. On my 88 model it was a black box, say about 4-5cms x 5-7cms. Just unplug it, ding ding ding is gone. There is another one that is attached to the door, and the head light beeep, so if that stops happening, then its the other one.

To get rid of it from this point, do 110kmh on the highway, AND THROW THE BASTARD OUT THE WINDOW!!!

thank god mine doesnt do that... wonder if it gets louder when u go over 180?? lol not that i have on the streets...

Everything else gets louder too tho, like exaust, diff, wind noise, rattles...

haha yeah my ceffy makes some scarey noises at around 140kmh... its those bloody wind/rain visors and the front bar flappin around haha

I had this old diesel mazda 626 or 323 (not sure) come into work yesterday, the lady had no oil in the car and it was playing musical tunes when the key was put onto accessories. Weird!!!

hahaha wtf?

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked... HTH
    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
