Ecu error 33

[Cocoloco]

Just thought i'd share this
I have a spare time to dig deep into this
Im having problem error 33
Ive decided to crack open my ECU
Check both of the transistor for igniton coil 1 and 2
Both seems to have same values
Havent found whats causing this
I'll keep an update to this

Update
Ignition transistor is okay.
Injector for 1 and 4 cylinder is not firing

Update
Solved by replacing one of the burnt diode
Part number in board "24"
brand nee ECU is on the way, just incase the repaired fails in the future

Are you refering to a diode Number 24 on the ECU circuit board or a switching transistor? Have you repaired the defecting ECU?

Ignition Transistor is ok however the Diode number 24, connected to ignition transistor is burnt.
The bike is running now on 4cylinders no CEL
This is a experiment i dont expect this to last long.
Scarcity of parts is what made me do this

Excellent detective work. I applaud you just for getting the potting compound off the board.

Wow. I dabble in circuits...even have my own reflow station.... But you, my friend, have courage and determination. EXCELLENT effort.....

We unsoldered the ignition transistor for cyl 1 and 4 to check if the board is still intact as you can see it has water damage
Im out for a ride tomorrow and see if this will fail on me.

Used Wiring diagram to see which is which. Then manually poking multimeter leads to the board to see where it all connected,
What ive learned is, if one diode is burnt some function of the ECU will not work especially the ones that needs negative trigger

Great work! What did you use to get the potting cleared away. Do you have a schematic for the ECU?
Maye you can clean it up,dry it out and repot it!

Finger nails and tweezers lol
Im not going to reseal it with silicone because i thinks its too early to do it.
No i dont have circuit schematic for the board, i searched all over the net using PCB serial number

Heres the video of it

Update
I replaced my old ignition coils from 2013 fz6r and body harness used but in good condition and she runs good,
Heres the catch
The repaired ECU , Sometimes error 33 shows up but goes away when i turned off and in the ignition switch.
Im still waiting for it to fail.

Hello my friend can you please put in a red circle where is the part number 24 ?
