ECU Problem...Continue to read...

Just replace the RP18 resistor to 1.5k resistor its will work fine

i think at jln pasar it quite hard to find 1.5k resistor. how about 1.4k? or higher from that value?
any prob from that value?

2 years ago my own car ecu had this trouble...
Never seen 1 with this problem from customer yet.

I suspect could be same cause as mine.... broken copper track .... trace from the iavc ecu pin into the pcb.... look for broken trace....

Worst case send it down to me... (i was the 1 that bought mfactory gear 3rd & 4th from u, sometime back)

Now fro the other way... the way i do it...

Remove- RP17 ( put alot of solder and just push it out)
Jumper- RP18. (000) or just small wire

Done!!! me?

Hi ,
what is the problem of P27 ecu takes a few minutes before the CEL goes off?
any idea's what to check? Already repalce all electrolytic caps.

thanks

Ic- ta8903sn

 

[E-Tech]

Ogip... try change this IC....

Looking at my stock, you should understand.... tq

I will try to replace that IC later. thanks a lot

 

[E-Tech]

Welcome... Keep me updated okay...

Welcome... Keep me updated okay...

E-tech,
I had a hardtime desoldering the IC-TA8903.
I replaced it and now the ecu is functioning and running great.
Another ECU saved and thank you very much for the great help.

 

[E-Tech]

Welcome bro Ogip.
Send me some "balut".. :-)

next time just bend it left and right until it breaks off
then only desolder pin by pin. Easy.

bring up post form diy....

just want to know what CEL code is this?happen after repair gear box and fix oil and atf cooler...

Sure or not???
Eld will not cause check lite to appear.

Only when you check for error code then only
you will know or c it.

Should not cause any problems.
If transplant engine with full wiring and fuse box
then will not happen tis problem...

Anyway hv you tried the bypass method?

 

[tks84]

fixed already....its the wire from the positive terminal not tighten enough....
then came out another signal...

cel code 15..
Ignition Output Signal missing or defective ignition output signal

stand in front of engine for half an hour couldnt find anything...
tried bypass still come back...but idling,start and drive no problem..
nia ma....go repair car then only problem come out....

check on the net...its it possible could be the starter ( as starter is the ignition)
cause its situated on top of the gearbox..
last week i change the O ring in the gearbox...so the mec maybe forgot something...

whats sifu comment?

 

[tks84]

sorry wrongly diagnose...actually its the ignition coil...my car don't have that just the distributor (i guess)
is there any chance to repair? like change the carbon inside/service?

 

[E-Tech]

You need to change dist.
To repair go get a b20 crv's dist and take
the ignition module and replace it to ur original
dist. Thatcshouls fix ur cel15

 

[tks84]

which is better?repair or replace? if i go to chop shop and get a recond wan better?
if a new set expensive arr?
cannot service?
can tahan for this month the disc? i pokai already repair a lot liow
