    For the last few days, in the morning, I was in the meeting mainly with Japan and then replying to many emails from NSX owners.



    In the afternoon, spending most of the time carrying out the Health Check service and now working on this CCU board.


    Considering even more busy schedule from latter part of this week, decided to push and finish this board.

    From time to time, at the time of my Health Check Service, the owner asks me to look into the A/C Climate Control Unit (CCU) as well.



    One of the owner was experiencing the typical CCU issue of FAN speed only operating at MAX speed.


    Initially, the owner was planning to send the CCU board through the post but as I managed to start carrying out the Health Check again, I asked him to keep the CCU in place.


    During the Health Check ...

    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.

    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 ...

    I think this board will hit the new history record for me for the size of the area that I had to scrape off due to acid corrosion.

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


    Challenge continues….
