Toyota Vios Digital Odometer Repair/Tweaking

Last month I've posted something about my damaged Toyota Vios 1.5G instrument panel containing my speedometer, tachometer (for RPM), fuel gauge and automatic transmission shift indicator (P/R/N/D/2/L) but now look at the picture.

How i did it? I bought an el cheapo digital multimeter at CDR King for P120.00 and used my dormant electronic repair skills that i've not used for many years. I'm na Electronics Engineer and been repairing stuff since grade 5 (when kids my age are just playing). It's a good thing there's also Google to show me IC parts functions and datasheets that enabled to to trace the problem with the voltage regulator. I used an old AC adapter to test/power up the unit prior to installation in my car. There's also the main CPU ship storing the odometer reading but no online information available. If i can get my hands on one I may be able to do Odometer rollback/tweaking but something i won't offer to anyone as that's cheating.

Note that this digital salvaging of a flooded/water damaged digital instrument panel saved me P30k for a new one from Toyota casa (price already with 20% discount). I almost ordered also a JDM (japan domestic market) replacement part from a friend's surplus shop (Jay and Jer) from a Toyota Funcargo, Yaris, Altis or Echo. (note the Toyota Innova also has a digital odometer but the gauges are "old school" analog types). I've seen digital ones also for Honda Civic but more elaborate.

  2. micoy, that's the problem with second hand cars these days, you're never sure unless you know how to check. where are you located? i'm in QC/makati. if you can remove the instrument cluster, i can probably take a look :P

  4. anonymous, check the fuses, baka open lang or an electrician. in my case, i got the gauge from the dashboard, that's why i was able to check and repair

  5. Hello paetechie, I'm having the same problem with my altis optitron meters.

    What's different with mine is that when I unplug the instrument cluster and plug again or unplug/plug the negative ground to the battery, the instrument panel lights up. But only until I switch off the engine. When I start up the car again, the panel is again dead except for the indicator lights.

    At least I can give a possible problem/solution - (voltage regulator) the next time I have the panel checked. The regulator is an IC?

  6. joseph, hmmm, i don't think it's the voltage regulator, probably just a car electrical wiring problem. if the voltage regulator is dead, the instrument panel is expected to be completely blacked out i.e. dead. trace the wiring connections up to the power terminals of the instrument gaude cluster.

  10. anonymous, sorry for the late reply. your problem may be electrical in nature, an open circuit. it's best to monitor the wires with the instrument cluster in full view.

    anonymous, digital instrument cluster of toyota innova? the speedometer and rpm tachometer are analog? you may need an electronics technician to troubleshoot it. remove the instrument cluster module from your innova and bring it to an electronics repair shop. if your technician is worth his salt, he should be able to find the power supply leads just by tracing the circuit without the actual schematic diagram
