Digital Odometer reset itself.... !

[98GT-Biarch]

This happened to me about a week ago, about the same time I bumped my turbo timer ON/OFF button which killed all electrics while driving. My ODO went to ZERO. How crazy is that??? It was at about 108000 and now is at 210.

Most probably I will have to remove the EEPROM and reprogram it.. fun stuff.

Anyone heard of this happening before? My wagon is a 98 GTB BH5. I had installed a budget car alarm and turbo timer just previously, so this is surely what caused this.

Are you sure that the trip meter is'nt showing ??

Had a couple of customers go balistic thinking that there was a problem, when it was just a matter of pushing the trip/odo button

Yeah I checked that, its definitely the ODO, the trip meter started resetting first which is annoying because I used it to gauge fuel consumption. The actual odometer reset to zero just once, it has not done it again since and is clocking up normally, and the trip meter seems to work normally again. Also the clock always changes to a random time each time I start the car.

I got talked into installing this alarm by my mate who said it would be a breeze, he's 'done heaps of them' but I was not keen due to the complexity of the system on modern cars, I knew it would have troubles due to all the timing circuits that the legacy has i.e automatic relocking if doors not opened within 30 seconds of unlocking.

So now we've confirmed it really is the Odo, have you actually seen this before? I thought it would not be possible but it seems it is.

No, never seen Odo reset itself

Unsure of what you could have done or has happened to reset the Eprom

Sounds more like a "spike" cause could be anything from earthing fault to power surge or backfeed

[98GT-Biarch]

Yeah, probably a signal from the cheap ass alarm feeding back onto something it shouldnt be, it must be through the ignition or the door sensor... I still need to investigate. Thanks for your input mate, hopefully I'll get it sussed tomorrow. Cheers.

Power surges + flash are never a good recipe for data retention. I don't like your chances of restoring it though, subaru would be unwise to leave the odo open to reflashing, at least not without some fairly tight security. On the bright side though, what's the resale value these days on a 98 GTB with very low k's?

get out a dremel and etch the current(lost) kms next to the ODO that way you will never forget

wil only take a www.Carjam.co.nz check to find -Decrease 108000 since last check

Itll be a feedback issue with that turbo timer mate. Prolly hooked into your ignition wiring and i would prob say makingthings go funny.

I had a speaker wire that cut the casing on the sill panel and exposed itself to the chassis and made the turbo timer not work and it idled real high all the time like it was on auto choke. Only reason i knew was the headunit bought up failure and a very slight buzz in speakers. Tracked it back to that one wire and shrink wrapped it, then all the probs disappeared instantly.
