check mo kung may obd2 port ang sasakyan mo. You can test kung nababasa pa ang mga data sa computer box.
Check mo rin bago nagloko ang sasakyan mo kung nag ilaw ang "check engine".
kung may mahiram ka na computer box swap mo muna and try it.

Hi,

The answer is... mahirap malaman yan. Pero, kung ako sa iyo, wag ka ng umasa na ayos yan. Ang ECU, pag nagkaproblema... siguradong problema yan.

Sensitibo masyado ang electronics. Lalo nat nabaha ito.

Kung ayos naman lahat ng electrical system mo at ayaw pa rin... replacement ang katapat niyan.

Kung meron kang SCAN Gauge tool... (mahal ito) - at di niya kayang basahin ang signal from the OBD port mo... hindi ito sign na sira ang ECU...

Hopefully - makuha sa repair yan... pasyal sa Speedlab sa Quezon Ave.,

Pag di pa rin, evaluate mo - magkano magagastos sa bagong ECU... or mag Mega Squirt VEMS-1 (ECU replacement) ka na lang, mas titino pa takbo niyan.

ito yun site ng mega squirt na local. http://pinoymegasquirt.blogspot.com

Mods - please merge this to other related threads... there will be more queries about this issue in the coming days.

I assume that when you say " ayaw magstart" there is crancking but won't start. If not check your battery and starter. A broken computer box (ECU/PCM/ECM) definitely will not give you a starting engine only if there is no signal voltage to the ignition, distributor, camshaft, and fuel injector. This are all related so make sure you check all this possibilities before concluding a ECU problem.

A MIL (Malfunction Indicator Light) lighted in the instument panel all the time is also one of the possibility. But this is hard to tell because this may send erratic data on your OBD scanner. A stand alone scanner will not show any data but only a letter and a series of numbers this are OBD codes unless you are using a pc base Obd scanner which I am using this will show a detailed OBD codes at no start and data when the engine is running. FYI car models made 1994 below are OBD1 compliance and 1995 up are OBD2 (On Board Diagnostics) compliance. The ECU/ECM/PCM control different sensors for your car to have a better mileage, fuel efficient, power, and very low carbon emmission.

Hi,

I know you want to hear some pag asa with your concern... But I am not the one who will give you false hopes. MAs gugustuhin ko pang magalit ka na lang sa akin kesa paasahin lang kita na may pag asa pa computer box mo.

Ilang tanong lang... natanggal mo ba ang battery connection mo bago ito nalubog sa baha?

Hanggan saan ba inabot ng baha ang oto mo?

Malalaman mo ang sagot ko - pag nasagot mo ang dalawang tanong na ito... and rest assure - di kita bibigyan ng false hopes.

Just to give you an idea... ang electricals madali lang ayusin... ang electronics - may Hardware aspect at may Software aspect. Kung buo man yung hardware mo... malamang - may tama na ang Software nito. Software - ito yung programa sa loob ng IC ng ECU.

Parang Sugal lang naman ang gagawin mong ito.

I will just share to you a wisdom I learned in FOREX Trading some years ago.

If there is an adverse condition or situation... you need to cut-loose.

Ang cut lose situation means... Mas maige nang matalo or magpatalo ka kung ang trend ng economy ay pababa.

Maihahalintulad mo rin ang situation ng Ondoy sa isang economic downtrend. And pinaka matinong gagawin mo lang ay mag cut-lose. The more you hold on to keep your car in original condition... the more you are putting at stake.

Matapos mo gastusan lahat ang pagpapagawa mo... then and only then to realize that you will be spending more pa pala kasi, kelangan mo rin palang palitan ng bago yung ECU... mahina P100,000.00 - mas mura pa bumili ka na lang ng second hand na matinong kotse na hindi nabaha.

Just be practical.

Wag naman sana... na pinag pa praktisan lang pala oto mo, nag a ala chamba lang pala mekaniko mo... at pinagagastusan ka lang pala... naku- wag naman sana. Kasi baka matiyempuhan mo yung mga switik... na pag nakaamoy ng dugo - lalo kang kakatasan.

Kung ako sa yo... bigyan mo ultimatum yan.

NO CURE... NO PAY. PERIOD!

Bigyan mo ng isang araw.

Pag di pa rin mapaandar - PM mo ako.

sir ehnriko salamat sa reply mo....natanggal ko yung battery nya bago bumaha sadly lubog totally sya...willing nman akong magpalit ng computer box kung kailangan tlga, hnd ko na rin expected na babalik car ko sa original state nya...ang nakakayamot lng eh yung ibang kababayan natin alam na nga na nasalanta ka na meron png paraan para lokohin ka...kaya nga humihingi ako sa inyo ng konting advice kc tlgang ala p kong alam tungkol sa mga oto...gusto ko lng nman sana straight forward yung mga gumagawa kung sira eh d sira, kung kailangang palitan eh d palitan...hnd ko kc masabi kung niloloko nga ako ng nakuha kong mekaniko kaya im trying to research some facts...dami ko na dn napagtanungan...the problem is up til now hirap p dn kumuha ng mekaniko at electrical d2 sa lugar namin kaya khit na meron akong plano na ilipat na sa iba hnd ko magawa...puno p dn lahat ng shop...nga pala sir, salamat uli sa reply mo...much appriciated

Ok...

IMHO - next time na may kakausapin kang mekaniko.... NEVER - tell them na Wala ka talagang Alam sa oto. Just tell them, wala ka lang panahon ayusin oto mo kaya mo dinala sa kanya. Hindi naman sila maaawa sa yo, ang nasa isip nila... Customer ka... ang tumutunog lang ang Bells ng Caha de yaman nila.

First of all... ask them what their analysis on the problem of the car.

Second.... ask them why they come up with that analysis or diagnosis.

If they can make a credible explanation... and you understood it... that makes them worthy to be listened to.

Kelangan - maramdaman mo, na alam nila sinasabi nila.

Since natanggal mo yung battery mo... that makes you ECU 50% succeptible to damage... Since lumubog totally ang kotse mo... that only made it 90% succeptible to damage.

The survival rate of drowned ECU is 10%... or maybe less.

Now - let's do a betting game.

Are you willing to bet on a horse with only 10% winning chance?

Or are you willing to bet on another with 90% winning chance?

Repairing your ECU is like betting on a weak horse.

Replacing it with a new ECU is like betting on a strong horse with 90% assurance... but you can only win about 80% of what you put. Kung sa sabong - Llamado ang taya mo sa Lo-diyes! Sampu taya mo, walo panalo mo... pero malaki chanca mong manalo.

Replacing it with an alternative ECU like the Mega Squirt VEMS-1 is like betting on a stronger horse but only betting low... kung sa Sabong sa Dehado ka tumaya ng Pu-Anim!... yung Anim na tinaya mo... Sampu ang panalo. Since it costs lower but it guarantees Better than new solutions. Why? simply because it is fully programmable - meaning - hindi ka na at the mercy ng Car Maker or ng Car Dealer Casa. You can adjust your fuel mapping and engine performance to run leaner or richer at certain rpms... to suit your unique driving style. Ito lang yung idea na pwede kong ishare sa iyo.

With regards to getting a good mekaniko... oh well... mahirap talaga ito. Kahit ako, yung mga tinetrain ko, nasanay sa lumang bulok na practice.... I have to get rid of their old bad habits in terms of their work attitude. I need to constantly remind them of how the customer feels... To be always clean as they work... and to decide fast and quick when they see a red flag.

They dont have to try to experiment.... thats my job... all they need to do is follow the routine or the protocol... provided that the protocols of the shop is designed to work for the best interest of the client. To get the car fixed fast. The best interest of the client is actually more beneficial for the shop - but few shop owners really know this.

Anyway... I hope you can find a good mechanic soon. If you are in Marikina... I know of two shops... but I can't vouch for the other one yet... kilala ko lang yung tatay - kaso patay na yun... yung anak, medyo questionable pa para sa akin so I can't recommend him.

same model tayo. yan din ang naging problem ko noong una. nag crank lang.di ko minadali pag gawa. lininis ko muna yung car ko then binaklas ko yung ECU then lininis ko ng tubig lang. then pinatuyo ko ng 1 week. wala akong maheraman ng ECU so i decided to bring it to scan/ diagnose. ayos daw ang box ko. kung wala ka maheraman, bring it at your own risk na ipa test muna. sa JSPECS sa banawe , look for marlon. gumagawa yan ng box.
noong una di ako maniwala na ayos ang box ko kasi sira pa car ko, pero may electricals is working. i check mo muna linisin mo yung box mo, wag mo lang sprayan ng kung ano ano, i check mo lang ang capacitors kung may kalawang o basag sa chip nya.
then after a series of theorizing and consulting, naayos din nag change oil and fluid replacement, change sparks, High Tension Wires, clean servo/ idle/ throttle body/ clean alternator/ rewiring change of bearing/ check starter, eventually umandar na siya. sinabay ko na din sa interior cleaning muna, saka na detailing pag napatakbo mo na kasi mahal pa talaga. ngayon, alalay muna ako kasi yung transmission ko milky fluid pa kulay ng ATF. so kailangan ko pang ipa transtech kasi hindi makukuha sa isang drain ang pag- alis ng ATf. tumatakbo naman kaso ramdam mo na nabawasan ang performance. maayos din yan, ipa check mo lang and DO a research. wag kang papaloko. maraming paraan para maayos yan. 2 mazda same model ang naayos sa amin, una box, un pala mechanical. check mo lang ng maayos. one at a time.
