After confirming that there was no short circuit between the GND and IG/BATT pins, connected this CCU board to my Display module and powered it up on my NSX.




In the process of Function and Operation check as well as carried out the Self Diag test.



Note the special display.



This is the initial page of the Function and Operation check.

Started to rebuild so many damaged circuit tracks and pads.


After more than 10 hours, finally I managed to get to the point where I was happy to power up the board for the first time after receiving it.


At the end, I used 8 x hard wires, 4 x jumper wires for the rebuilt process, lots and lots of soldering bridges to reinforce the circuit pads against the noise and ripple.


I have worked on many CCU boards but this one made ...

Also, it will require lots and lots of jumper wire, hard wire and soldering bridge to re-create the dissolved circuit.


Challenge continues….

So, removed the capacitors and started the inspection and cleaning process.

Doesn’t look great at all…..


After the initial cleaning, it was quite obvious that some of the circuit tracks and pads were already gone/missing by the poor previous work….



Also, the leakage from the original capacitors were left too long that it dissolved so many tracks.

More than one month ago, my FL wheel speed sensor started to play up and triggered ABS #13 error code followed by #14.





The sensor was on back order and after long-long waiting period, finally, it arrived at my place.


Together within the package, there were two additional wheel speed sensors for the owner experiencing similar issue for a long time.


There were also some small ...
