Helo fellow suzuki carry owner, I'm new to this car bought my mini van 3 mos ago, since the first day I got my mini van it runs fine, though got some minor fixes since then like recharging some freon, cleaning the distributor.
Lately I noticed that when I tend to give the electrical system a load, like turning the lights on the idle speed goes up, but when I turn the load off the idle goes back to normal.
Can you tell what could be the possible reason behind this electrical problem thing (though I'm not that savvy when it comes to eletricals)
Greetings! As you stated when load is applied, idle goes up, load is removed, idle goes back down is they way it should be.
The lights require energy to operate. The system detects the drop in the electrical reserve, and tells motor to speed up so the alternator can do it's job.
When the load is removed, there is no need for the increased motor speed, the system detects this, and reduces rpm. Some have a ECM controller that does this.
I hope this helps you, I tried to make it a simple as I could, it is not as technically stated as it should be, but is the best I can do.
In short, your system is operating as it should.
It's kinda weird bro, when I got the unit 3 mos ago the idle seems to behave differently. Like I forgot to mention aside from the lights, when you turn the fan on in the dashboard but still not turning on the A/C the idle still goes up. I'm expecting it will only goes up when the compressor kicks in.
I try to get back to the guys who did the electricals in North recla just this afternoon where I got the unit but as useless they have no after sales service (that sucks!)
Newsavedone is correct. The normal rpm for the engine is around 600-800 rpm it will increase to 1000-1200 rpm with respect to increase of the load especially when the cooling fan, lightings and aircon kick in. What type of engine you have Sir, do your system using ECM?
I'm really sure what is an ECM and what it look like neither where it's location Bonita. Can you guys refer an image. With respect to the engine, well not quite sure but I think its an F6a or something, I've read it somewhere within the engine body.
Also I had the freon refilled, and there's this 4pin socket I think that is located just above the exhaust manifold that he removed, he said it can cause high idle and can cause high gas consumption I wonder what wire or circuit it could be.
Greetings! The ECM is located beside the battery compartment. It looks like a hard drive, which is about what it is. it is non adjustable, and do not let any hack tell you it is. This forum is filled with post about fried ECM units someone tried to adjust.
The 4 socket connector, did the hack also disconnect it? If so, have him reconnect it.
Your unit is doing what it is designed to do, why do you keep obsessing about it?
If the idle does not increase with a load, you have a problem. If you keep on the path you are going on, I can tell you will be posting about a wide variety of problem that come up on vehicle you were pleased with when you bought it. VERY FEW mechanics here know anything about how the ECM circuit works, they seldom have been to school for any vehicle, and I would be very surprised if any have been to F6A school in Japan.
Usually the problem we encountrered is other way around. The only question is how much RPM you've got when you have the load! If youre engine still using a normal carburator then there is adjusting screw to control the high RPM during load. By the way Sir where do you leave? Maybe some one on this forum can advise you where to go for a good mechanic ( my wild guess only) im not saying its a problem but it will help you to clarify something thats bother you. Just keep in touch bro.
Usually shell mactan has a good service but its far your location just try caltex service in inayagan after mary help don bosco, there is a good auto electrician familiar with multicab maybe he can help you. ( caltex service is beside the mini store with small service bay on it) another suggestion is to bring your unit back to the dealer and tell theme to replace the ECM/ ECU temporarily with a good one just to check your system. Its plug and play so it will not take so much time to replace it.
Inayagan is near in my place, I will try to approach the guy I'm quite familiar with his store. Well with the suggestion to bring back the unit to where I bought it...darn! I dont get any after sales from those guys, I wen't there twice but they always said that we are busy we have lots of orders.
Just a heads up for those who are looking for a multicab unit to never do business with that surplus shop, they are located across the old burnt whitgold mall.
