Good job for giving back life to Honda ECUs.

Note, the trick with RP17 RP18 for auto manual works on P30, and it's knockboard-less brother/sister? :P, the P08. But shouldn't need to be done if you already put in a chip, since that'll disable the auto anyway.

ELD code means you overloaded the electrical system (added accessories? shortcurcuit?). The ELD is in the fusebox, but it's not the ELD that's the problem.. what kind of repairs you did? :hmmmm:

actually i fix the cel 20 liow...just tighten the batery screw, reset and it goes off but the CEL 15 keep coming back..search it on the net says it ignition sensor... Lagi blur me...

i suspect it the Dist problem as when start engine i just gatal gatal go touch the thing then
!@BHCWKJ kena electric sial!!!! then dont dare touch liow...

i was told by another forumer to change it to B20 Dist...
then i was thinking of getting from kedai potong...can get same model meh? or just drive the car there and show them?

e-tech, when switch on the ignition key, engine light stays on for a long time.. some times a few seconds to a few minutes before it go off. then the car is able to start. what might be the problem?

 

[E-Tech]

hi ice....
Which ecu is this?
Are the caps good or leaking?
Have photos?
Will try to assist you...

 

[iceman401]

i will try to get pix..
it happen to both of my honda..

Stan... Since u got 2 ecus... You might want
To send me 1 to have a look.

 

[iceman401]

bro both ECU used by two different cars..
so can't removed cuz no car to use ord..
i guess might be the problem of the caps or the IC?

 

[E-Tech]

orangais,
how? fixed ur problem oledi with the parts?

 

[iceman401]

not yet bro, busy working..
hopefuli this weekend..
if after changing caps, still got problem how le?
have to change the QM1,2,3?
the engine can start. once started, then it dies off..

 

[E-Tech]

Iceman...
If still still problem, send me pictures of
The ecu..
Any error codes?

 

[iceman401]

unable to detect codes now. not sure what had happened. once jumped the socket, the check engine light blink abnormally. not sure what had happen here.

 

[E-Tech]

???abnormal?
Test on another car and try to get the code.

 

[iceman401]

bro, i replaced with another ecu. replaced all the caps and ic17.
car can start but now showing code 14 and 20. any idea?

Code 14- iacv
Code 20- eld.

14 needs to solve if not idling up and down.
Check the related transistor to iacv.

20 should not be a problem...
