You might have been bitten by the crappy Denso Injector bug (same problem as the D-4D).

Alterra was relesed yesterday.

Finding was that the Immobilizer needed a reset.. (Again????) it has been reset for how many times already during its warranty coverage and after warranty still the same process.. immobilizer is always blamed (last year it was twice it was reset)... i already asked them what causes the immobilizer malfunction, they told me 1 reason, dont quick switch on/off the engine if it doesnt start (puro redondo lang). This will break the immobilizer, i made a followup question before we did that, why in the first place the engine wont start? (puro redondo lang) ... .. the answer.. no answer... during the diagnostics they found out that the program in the immobilizer is not working this is why they need to reset the immobilizer... no further explanation... What the !*#$! I've asked them what made them decide to reset the immobilizer? its because there are errors, but what causes the error... not properly explained... hayyyyy....... I need to know what is the root cause of the problem and not an interim solution only.... Im guessing we got a lemon unit with defective immobilizer and was hidden or ignored or overlooked by the casa mechanic when we first encountered the problem.... tsktsktsk.... Its a good thing its casa maintained, i already called isuzu philippines head office to look into this matter. Im just waiting for their feedback..

But anyways, the alterra now is working, thanks to benzmizer and the contact person he provided the service manager, he is very attentive... and take note of the problem.. but im not satisfied to the conclusion... Im no expert mechanic, but the frequency the immobilizer is bugging down, tells me there are other problems they are not looking into or simply ignoring...

No worries my friend. I, myself, ain't satisfied with how your queries were answered. In the meantime, observe the unit. If in any way the malfunction recur, let me know. It'll be a good time to test the damage extent a pack of C4....

Good thing Immobilizer lang pala and not the engine. Hassle lang talaga.

You are right, you need to find out what's causing the immobilizer to err.

But wait,

Hindi ba ECU ang ni-reset nila? Kasi ang injectors controlled ng ECU, and if it errs, di talaga gagana ng matino ang engine unless i-reset/burahin yung error codes. Make sure that Isuzu is not giving you the run-around.

Sa Toyota D-4D problem kasi, ganyan din ang stop-gap measure nila. Pag nagc-choke yung engine, ire-reset yung ECU para gumana for the mean time. Meron mga balik nang balik, meron namang naayos at bumalik after a year or two pa.

Good luck

*benzmizer : Thanks again. Right now alterra is running Ok.

*horsepower : yeah i also read about some of the D4D's issue specially on certain Gasoling brand... i dont want to mention the gas brand as it is not affecting my Strada, its just the alterra that is having problem when it was loaded with it

anyways... we are not loading that type of gasoline/diesel brand in the alterra just to eliminate the gas/diesel issue.

*** anyways, ill be monitoring the performance again, and soon will post if there is another problem of the problem re-surface again.... I already called isuzuphils, im just waiting for their feedback on my concern. or otherwise ill be walking at their doorstep

(like what i did with near by dealers in the area) their Corporate management was so sorry and immediately lighted some butcheeks on the dealers

for my filed complained

*benzmizer
correction on my post, I was informed by may dad, the problem was experienced again thursday, although he thought he didnt start the engine properly so he did noticed that the hard starting is back again... Friday, definitely there is a problem as it takes to 2-3 times before the alterra is to start. And just this afternoon is the worst.... it wouldnt start at all after following what the technician mentioned how to start the alterra if hard starting was experience, this procedure was executed but Failed, the alterra doesnt start at all. my father is about to call in the towing service when he just tried to start it for the last time.... and... it did start.. he just went home to be safe and not be bothered by the engine problem... so instead of doing some other walks he just cancelled it and called me later this afternoon to inform me for his frustration on how our alterra was poorly service by isuzualabang.. there is some areas that are being overlooked . For me, this is becoming an Issue now... Im still hoping your Big Guns can do something about it.

Thanks again....
