    Pag turn on the ignition, walang nailaw sa dash board. As in kahit anung indicator lights wala.
    Tapos kahit busina at ilaw wala.
    Last March lang pinalitan ang battery at sabi ni utol ok pa naman batterya nung ni-recharge nila.

    Since busy ako, si ermats nagpa tingin sa electrical (mejo kilala ito sa lugar namin)
    Ang sabi sa kanya ecu daw at starter.
    4.5K ang total damage. Repair lang ng ecu gagawin dahil mahal daw ang surplus.

    Wala kasi ako time masyado para i-oversee yung repair. gusto ko lang malaman kung most likely ba ecu nga problem sa ganung symptoms.
    Or kung fuse lang problema, anung fuse kaya dapat tingnan?
    Tingingnan ko na kasi yung sa driver's kick panel side, parang wala naman fuse for ecu dun.
    San ba location ng ECU fuse?

    Ano ba ang ibig sabihin ng ECU repair? Kasi ang ECU ay computer ng sasakyan, so ano ba gagawin ng mekaniko kapag nirepair nya? Ang alam ko sa ECU is reprogramming pero you need some advance tools para magawa mo yan.

    ok check ko main relay at ignition switch.

    actually, hindi ko din alam kung paano irere-pair yung ecu. assume ko na capacitors and the like yung titingnan at hindi yung program.

    find a better mechanic

    the horn is wired to function independent of the ignition key ... it operates via a relay ... if it does not work, check connections to the battery, horn fuse, or relay

    if in addition to the horn, your ignition also does not work ... the culprit is most likely connections to the battery or the battery itself

    the ECU and the starter are not suspects with the symptoms described

    assuming that the battery is good , it could be your main fuse busted , ground or loose batt wire going to the fuse box

    nasa engine bay located ang fuse box for the ecu, left side if you are facing your car, sa loob ng fuse box look for the 15 amp fuse sa may lower left side. I doubt if ecu ang faulty, pag ecu kasi dapat steady ang check engine light, focus ka sa electrical side, start with the battery connections and ignition switch.

    Separate circuit ng ECU sa Starter circuit. Kaya hwag ka maniwala sa mechanic na iyan. Basta ang mechanic ay hindi alam ang sira ng kotse ay ECU ang itinuturo. Standard iyan.

    Be sure na ok ang Battery. Dapat sumindi ang gauge kapag naka switch sa ACC or Ran ang Ignition Switch. Check mo rin Dome light kung sumisindi. Kung walang sindi ay may open na fuse. Pero kung sumindi ang ang Dome light ay check na yun Ignition Switch. Di kasi dumaan ang Dome light sa Ignition Switch.

    Ok thanks for the advice. Now I just need the time to personally check the fuse and wiring. The service manual is just to voluminous but I'll try my best.
