Corolla '97 ecu problem. HELP!

[matsuda0870]

[SIZE="3"]Hi sana po matulungan niyo ko dito sa problem ko.. recently lang dahil sa ondoy di ko alam na nabasa ung ECU ko. di ko kase alam na nasa floor pala halos siya nakalagay. pagbukas ko ng ECU may isang part na SUNOG... tapos ayun di na magstart car ko. don't have enough budget to buy a new one or a surplus one. pwede pa ba marepair ito? kahit replacement lang ng parts inside? a lot of my friends just made it repaired lang and it costed around 4-6k.

Please please please suggest po kayo ng places or contact na pwede kong tawagan. i'm living in CAINTA area po...

thank you...

You can also try changing it to a local ECU alternative....

Given the megasquirt costs well over P10K, it's pretty much clear that it's beyond the budget of the TS.

Hello Matsuda 0870

Regarding your burned ecm I saw the picture and it seem that it is repairable since the technology was not of latest smd type or surface mounted devices. But the consequences that you may face is that if that burned part affects the main cpu. Not only that if your car was not properly cleaned and all other electrical component controlled and feeds data to the computer such as relays and sensors have moisture in it, this may cause your computer to have short circuit, even though you replace it with a new one this will just cost you more since it will just get burned later on. I suggest for you to do this step to look for not just a conventional mechanic but who knows the latest trend of cars. FYI model 94 and below are OBD1 model 95 and up are OBD2. OBD's are the On Board Diagnostics consist of the PCM/ECM/ECU this are all the same ECU, is used by toyota. Manufacturer have gone to the latest OBD2 the reason is that, for us consumer to have a car with a better fuel efficiency, more power and very low emmision to protect our environment. Try to call this number and ask for estimate 09207802689. Thanks

I sure hope konti lang sira ng ECU nila... otherwise -- talagang magastos.

thats the reason why people should really remove the battery connections in case or in the event of an anticipated flooding.

I agree with what EWA boys said, if the problem reaches the main CPU - thats like the main brain of the module... then - fixing it will not really be a good idea.... it's like throwing away money.

Some wisdom from the elders... sa paghangad ng isang dakot, isang salop ang nawala.

Check out first how much CASA, Speedlab or the number ewa boys gave, see if you can afford it. I'm pretty sure they wont make you spend if the ECU is diagnozed to be beyond repairable condition.

The parts that shown, a Power Supply(PS) section, madaling marepair yan
or worst thing bakit nasunog ang PS Section may na short sa main circuit.

Can you post more clearer pics of the damaged parts including the back(PCB foil side)
Tingnan mo kung may naputol na PCB Foil sa ilalim,
Kung makakuha ka ng clear pics, please use MS Paint to pinpoint the damaged electronic parts
Pakikuha nadin ang Part Number ng ECU mo, nasa Casing nakalagay yan.

Just pray na diode lang nasunog....

Bro, madali lang i-repair yan. Yung sa akin nalubog din sa baha, pero yun lang kasi tinangal ko na battery before pa abutin. Kaso nag corrode yung mga terminal nung sa akin. Pina repair ko lang sa kaibigan kong nagrerepair ng mga Electronics since sya yung meron Hot Air (ginagamit ng mga nagrerepair ng cellphone). Ganun lang ginawa nya para ma re-solder yung resistors, caps, diodes etc...it cost me 1700 sa repair distributor & ECU na yun.

Matibay ECU ng corolla big body, tama si ewa_boys. Yung board kasi nyan hindi pa surface mounted unlike yung mga boards ngayun kahit i compare mo ang kapal ng PCB nyan. Madali palitan parts nyan sa raon makakabili ka ng mga pyesa na papalitan.

Advice ko lang since naka tambay sa iyo yung ECU mo bili ka muna ng flux grease, para hindi mag corrode yung mga terminals. Flux grease yung ginagamit kapag nag sosolder na parang paste. lagyan mo lang muna yung board using old toothbrush.

Goodluck sa ECU mo aandar din yan Rolla mo.

lahat ng parts sa ecu madali palitan. hanapin lang yung nasunog o naputol na connection. pero kung ang nasunog ay yung rectangular shape na parang centipede, hanap ka na lang surplus na ecu.

Yes tama po si orlee_v. IC or Integrated Circuit po yun na design for such commands. Other than that yung mga Transistors, resistors, capacitors, diodes kayang kaya palitan ng bago.

natutunan ko sa electronics 101 ko nung college. hehehe

Thats the problem... yung IC chip na yan... yan yung pinaka CPU (Central Processing Unit) The Main Brain ng ECU board mo.

It cannot be repaired once it has been damaged, since it is basically a disposable item.

Of course madaling gawin ang power supply - caps and diodes lang ito basically... it's a rectifier and smoother circuit by design. But making the board alive will not guarantee you that it will be back to normal again.

Ang analogy diyan... naaksidente yung patiente... sumalpok yung motor niya sa bus... buti na lang may helmet... kaso medyo unconscious at maraming dugo ang nawala - may sugat sa ulo...

Nilagay sa ICU... nilagyan ng Pace Maker para magtuloy lang ang pag tibok ng puso at pag hinga... so para maka survive... at mabuhay, ginawan ng paraan o remedyo.

Kaso... nung nabuhay na siya... at naghilom na ang mga sugat... gulay na pala. No more brain activity anymore. So - spiritually - in essence - parang patay na rin.

The same with your ECU.

The flood is the worst thing that can happen to it. Of course... magagawan ng paraan din yan para mapaandar ang oto mo... pero, dont count on it for longetivity or reliability.

Ika nga ni Confusious, 'Haste makes waste'... Sa hangad na makatipid... lalong napalaki ang gastos. Sa paghangad ng isang salop, isang bugkos ang nabuhos.

These words of wisdom are based on experiences of people before our time and they still are applicable today.

I am not throwing water over your determination to have it repaired...

Electronics items are super sensitive things... it's sensitive to static and with our moisted finger tips - it can already be destroyed... lalo na kung flood water which can serve as a conductor which can easily short any circuitry. Some electronic components retain capacitive charges where if shorted will give high votage surges that can zap the least resistant of everything near it. This is what happens to your ECU in a flooded situation.

I hope this also adds light.

Ingat lang doon sa magpaparepair the ECU sa Banawe iyong mga nasa labas na walang puwesto at marami na nakapagsabi na may warranty ibalik lang sa kanila at mahal ang singil nila . Iyong kakilala ko nagpagawa at ng ibalik niya dahil nagloloko rin wala na sa pwesto iyong gumawa sa kanya. Kaya doble gastos nangyari sa kanya.

First run of "Storm Ondoy" devastated Mitsu Montero '94 6G72 running and idling smoothly with the latest Alpha_303q burned into my self built MS2 daughtercard and Custom Designed PCB routed Megasquirt with provisions for Peter Florance's sequential injections!!! idling stepper motor is totally busted modified it to used a printer stepper and it worked and way better than that of the stock Stepper!!! Can't find a replacement for the busted Distributor so Modified the Dizzy to used a fiber-optic tru-hole sensor and it worked perfectly!!
