Wow thank you I've been up and down fighting my car testing checking and changing parts. Went and re soldered the ecu on a few parts that didn't have much to any solder and ones that looked cracked. And wish I would have seen this. Would have went and grabbed a new transistor for c17 and been back in business. Thank you so much
Friend, I have 2 ECUs, P0B-A01 Accord LX M/T. Both times I replaced all the capacitors with the correct specifications. One of them, when I turn on the ignition, the car has the injection light on for about 3 minutes and if I try, it won't start. After 3 minutes it turns on and the injection light comes on indicating error 9. The other central, sometimes the car starts perfectly and the injection light does not appear. But sometimes starting is very difficult, you have to press the key a lot and step on the accelerator. What do you say about each of these ECUs? Help me please. Tks
I did all.my compacitors an now I have no voltage too tps do you know what in the ecu could have fried or what compacitor goes to tps I should re sauder?
How do I fix the memory problem? Have one with solid cel. Primes and car starts, the cel is just solid and can’t get any flashes when it is jumped. TIA
I have a ecu that is chipped with s300 and the cel comes on right away with cyclinder 1 code. When I had the changed the board the another ecu the check engine light went away. What will cause a cyp code? Possibly bad capacitor
Hey man i need a little help. thank you so much for this video, i had 2 ecus like this my ecu i changed myself worked just fine. The second one was a friends but had delayed fuel prime. told him the ic17 power supervisor needed replaced to send it back to where he just got the ecu. well they changed the ic17 and now it has solid cel but does prime and start. Runs like crap. Any ideas what this could be so i can fix it?
Hi! Got sólid cel with no fuel prime , already changed ic17 and all caps and still the same! Already changed caps on other ecus and worked fine! So its not soldering problems... Any tips? Maybe ic12 is damaged?
No power on Q10 pin 1 indicates a bad +5VDC reference - which would affect other things than just fuel pump .The solder joint at Q10 pin 1 could be corroded or damaged with age.if it doesn't work change QM3

Hello, I have problem with chipped p28, when i turn off car 3 dashboard lights start barely lighting(engine, battery and oil), even if i take the key off from ignition switch. Car runs perfectly.

I turned on the engine check when I stopped to refuel. it lights up and does not go out, it stays on. I tried to make a diagnosis but the light stays on and does not make a diagnosis.

I have a d16z6 full stock. Recently replaced the capacitors with same specs correct polarity and proper soldering( checked 2x). All running properly but sometimes the CEL pops out.

@@YayaAndCars thanks so much for the reply. I did in fact confirm online that is what the code is for. But I’ve never had that issue before. It’s only this ecu telling me that code. I’m so confused 😵💫

Great information, I have a P06 that’s running a b20 in a 2000 civic coupe I have a solid CEL and the motor starts and runs (fuel prime) rips actually, full throttle feels great but it bucks at the lower RPMs, I have swapped to other ECUs (obd2) and it runs also with no solid light so I can confirm it’s my obd1 computer but what I’m wondering is will the car still run with a corrupted memory chip? I would assume when an ecu goes bad it wouldn’t run and drive which it does but I cannot tune anywhere around the idle or even 2k rpm and lower it just cuts out and acts like a tps is malfunctioning, I’ve been needing to chip the 28 pin anyway for the b20, is it possible I can get two birds stoned at once and chip my computer (more optimized) and get rid of my solid CEL ?
Thanks bro, in my case i change all the capacitors and doesn't works and after that i change the IC17 and that resolved the problem!🙌👌👍

Is there a way to test ic17 in or out of the board?
I have a ecu that is chipped with s300 and the cel comes on right away with cyclinder 1 code. When I had the changed the board the another ecu the check engine light went away. What will cause a cyp code? Possibly bad capacitor
It would be safe to change them as a precaution, but it could be the HIC modul (the two long vertical PCB), it is responsible for these sensors
What about if I have fuel pump priming but no fuel coming through the lines with no check engine light?
Do you have fuel in the tank? Or does the fuel pump work properly?

Yep it can manifest itself as this
I have replaced the capacitor, but the problem is still not resolved. Do i have to replace the ic 17 too?
Yep most certainly
@@YayaAndCars ic 17 must be programmed or just replace it?
@@panduraga did replacing ic17 work?
if its no spark, n the culprit is ecu, which part in the circuit board cause the problem? thank you.
It's the ignition transistor q38 I think
Have any tips for fixing CEL 9? Ecu has replaced capacitors and ic17. Thanks 🙏🏽
H1C1 daughter board has more then likely failed.
my car takes long time to prime is that a capcitor or memory issue? P06
Most definitely the capacitor, and with time it will burn the ic17 completely, get new caps as soon as possible
code 14 changed iacv light still on so my chip is corrupted?
Check your harness continuity with a multimeter first
Now thats what I'm talking about. It there anywhere a guy can get an actual schematic? Cheers
I used to have a detailed schematic of all the components of the ECU, have to check on my old files

first remove as much solder as you can with desoldering wick or a small vacumpump, then use a smd rework hot air to fully desolder the ic17

where 4-wire 02 is controlled on p28
The heater circuit is controlled by one of the 3 big circuit on the top left of the ECU , they are Darlington transistors
I have fuel prime, with CEL flashing code 21. (2 long cel flashes & 1 short flash) p06 with hondata S300
That's the obd1 code for VTEC solenoid valve malfunction it I'm not mistaken

Check if the ECU is correctly chipped, and also the condition of the vtec transistor, I believe it's ic13 or ic14

I have a p28, all capacitors are new but I get no injection on cyl 4 is it a ecu problem? The injectors are changed and the cables are new. Thank you
It is chipped
It's most likely one of the STA460c, they are the 3 long circuit on the top left of the ECU, they are responsible of powering the injectors
