- Replacing a bad capacitor in the computer from my parts car so that I can use it in my project car. The replacement capacitor is a Vishay brand from Mouser electronics: 75-678D476M050CC4D
678D476M050CC4D
47uF 50volts 20%
I’ve seen other ecu removal videos before but yours is by far the best one I’ve seen.
Thanks.
Use Nichicon PJ Series 105C caps! Just recapped a 1998 Sidekick ECU. It had two PJ series Nichicon's one 47uF 50V and one 47uF 25V. There was also one Rubycon 47uF 25V. Since I have an ESR meter and capacitance meter (a lot of regular voltmeters can do this) I checked them...The Nichicon's tested out like new whereas the Rubycon's ESR was twice as high as the Nichicons and the capacitance was a little low (44uF). Although the Rubycon was still good enough, the Nichicon's ESR values were half of the Rubycon's. For the most reliable caps get the Nichicon PJ Series.
Thanks for the video! I got a 1994 with a bad ECM, I need to pull in a couple of days. It's gotta be bad caps. I live in Arizona and it gets super hot here. Drys electrolytic caps. right out.
On a '94 model, from all that I have studied, the chances are good that it is the exact same problem as the one in this video. Mine is working fine now.
Sir I love it your job. I wish to be a your voluntary student 😅😊
I could use some help. I'm doing body work now. When can you get here to Tok, AK? Smile.
@@nunapitchuk sure I ready,
Sir I need two things
Number 1 wiring diagram with IAT Present, and Number 2 one opportunity to talk with you.
I Suzuki Sidekick and geo tracker, and have a lot questions,
@@nunapitchuk Dear Frank, do yoy think if you I take thermostat off in this car it spends to much gasoline
My friend are you from Alaska?
@@hectorrojas8932 Yes.
The component I wanted help with lies just besides the four green components it’s black and I see it’s ceramic with 8 pins protruding on the back side. Wish I could send you some pics but I am not good with these phones,thanks.
I don't know what part you are talking about. You can chat and send photos on my face book page: facebook.com/SidekickRebuild/
I think your 1995 ECU will be looking for the thermoprobe input from the EGR circuit, and will throw a code 51, if you’re putting this into a 1993 vehicle.
It is going in a '95 vehicle to replace the '93 ECU that was in the car. To make the '93 ECU not cause a check engine light I just unplugged the the EGR. It was working fine, but now I have this one in the car and it is also working fine with the EGR plugged in. No codes yet.
handy video! Thanks.
i guess it is kinda randomly asking but does anyone know of a good place to stream newly released series online?
@Simon Kellen I would suggest FlixZone. Just google for it =)
I have a 93 but i dont have fire on the cylinder 2 and 3 i change wires spark plugs distrubuitor cap rotor and nothing
Does not sound like an ECU problem to me. You can chat with me on my face book page: facebook.com/SidekickRebuild/
Hi Frank I am Edward living in Vietnam,wanted some help and advice regarding my Suzuki the ecu is similar to the one your replacing same specifics I am not a mechanic but if I could find the name and number of this burnt part I might get some help and fix it .your advice to fix it or get a replacement will be highly appreciated .

Hi Frank, what was the symptom before this? Thanks
Sorry, I don't know. The car was not running when I bought it to rebuild so I never started it before I rebuilt it.
Heya! Great video mate! Just a question: my ECU is repaired but now when I turn on the engine, the RPM stays at 800...there's no "peak" when I turn the key on...it just start and so...also it doesnt go up with rpm when the engine is cold. I know it usually go up to 1400/1500rpm till it went hot enough...Can you please tell me what can be the issue causing this? Thanks!
My first thought is that the temp sensor, below thermostat housing, might not be working. You can can talk to me more about it on my face book page, suzuki sidekick restoration project.
Leo LADA You don’t advise what your engine is - the 8v and 16v have different set ups for cold start. The 8v has a throttle opener that remains open for about 5-10 seconds, and gives you an rpm of about 2000 rpm, then drops to 1500. After that, both engines are the same, and are governed by a mechanical wax pellet valve that provides additional vacuum as the engine heats up to melt the was.
@@Inisfad Uh yeah sry :) 8v engine here
Leo LADA Do you still have the problem? Frank Cook advises that you should check the coolant temp sensor - which you should, although your problem may be elsewhere. This is what advises the ECU whether your engine is cold or hot. It’s the round blue/green sensor on the right side (as in right hand drive) of your engine. Check the connections at that sensor, as well as the ohm reading across it. When your engine is cold, that ohm reading should be 3000 ohms or more. If that sensor is not operating properly, the ECU doesn’t know if the engine is hot or cold. Also, the 8v engine has two vacuum solenoid valves that sit together at the front of the engine - one is blue/green and the other is brown. The brown one is the VSV for the throttle opener. If you follow the vacuum line from that brown VSV back to the rear of the engine, you will find the throttle opener - on the engine, sitting across and slightly down from where the distributor is. It has a diaphragm in it that can be open or closed. The default position of the throttle opener is open (which would give you vacuum and cause your idle to be high). When the ECU comes on line, that brown VSV energizes and provides vacuum to the throttle opener, which then closes. So, you may want to check the throttle opener - make sure that it’s open when the engine is shut off, and that you can (very carefully, so that you don’t rip the diaphragm) move the diaphragm open and closed. The wax pellet valve, however, is not connected to the ECU or the electronics of the car in any way, and if this is operating properly, you should have a cold rpm of about 1500 or so, when the engine first starts. This is located behind a metal plate to the right of the throttle position sensor. If you take the metal plate off, you should see an air port on the right side of the housing, when the engine is cold. This is what provides extra vacuum to the valve. If you want more info, you may want to post on Suzuki-forum.com.....
I have abought a geo trakcer that was siting since 2002. It drove very good i parked it and when i try to restart im getting a cliking sound on the fuel pump relay and under the engine hood by a smal actuatir thing that has 1 or 2 vacuum hose runing to it..
I have never worked on an 02 model, but my first guess is weak battery or poor connection to battery because when the computer does not get a full 12V then it does things like you describe.
Right, what are the capacitors you used?
Vishay C-103 from Mouser Electronics. Also, check other comments below for more about the capacitors.
@@nunapitchuk The comment below shows capacitors from a 1998 device. the 1991-1995 is different
@@Administrator7 Took me a awhile to find the reciept, but here is the part information from Mouser Electronics: 75-678D476M050CC4D

hey i have problem no injector pulse whats the problem? vitara 1993 1.6 16valve
I think your car has a single injector. So it could be a bad injector or the wire/fuse to the injector. Did you take it our and test the resistance of the injector and do a continuity test on the wire?
@@nunapitchuk they have 4 injectors. i pull out all and not working fuel dont came out. i test when starting 5volts been there.
maybe imo or they not imobilizer?
@@nunapitchuk wire on injector to the ecu is good
@@davisleija1314 I think the injectors are fine because having all 4 go bad at the same time is unlikely. It has to be an electronic problem. If you want to message my face book page I can try to help: facebook.com/SidekickRebuild/
my engine light flashing, flashing dont show code. Why ? flashing again in again
Sorry, but I don't even know what kind of car you have or any other information so there is no way for me to know why your CEL is flashing. You can try to contact me through my face book page, suzuki sidekick restoration project, and provide more info and I will try to help if I can.
@@nunapitchuk 1995 2.0 v6 vitara 5 door
That is a much different car than mine. You might need to find a service manual. Here is a link to a forum that might help you solve it: www.suzuki-forums.com/suzuki-sidekick-escudo-vitara-geo-x/44508-check-engine-light-keeps-flashing.html
Do u have this ecu diagram?
I think the schematic is a company secret as is the program that runs on it. I tried to find more info, but nothing. Fixkick dot com did some study of them and posted some interesting information. You might want to check it out.
How do i remove my computer?
Close to the end of the video, I show how to remove the ecm from the car. Take the left speaker out and remove the plastic piece under the steering column to get access. If you watch the second half of the video, you will see how to remove and install.
bom dia comprei uma
What did you buy?
