T3TEC NSX Gauge Simulator

Rate this Entry
The latest development at T3TEC in Japan.
Very useful equipment.









I would love to have one in order to analyse some of the strange behaviours of the gauge on our NSX and most importantly, re-adjust the speedo and rpm dial after replacing the capacitors.

It can test all of the displays, warning lights, light bulbs and most importantly, the ‘BRAKE LAMP’ warning circuit that may catch fire at some point in the future if left without being treated.

With these tools developed in-house by T3TEC, already more than 70 gauges were refurbished in Japan.

I want one......

    Hi Kaz, can you share more details about brake lamp circuit catching fire?

    as above?
    why does it catch fire and what is the fix?

    The main cause of the fire or the smoke is the acid leakage from the caps around the warning indicator module circuit behind the actual warning display.
    It’s on the rpm gauge circuit board.

    Most of the time, the first symptom is that the ‘BRAKE LAMP’ warning stays on despite all brake light bulbs are operating fine with similar OEM spec ones and also even after checking for any corrosion inside the bulb sockets or the female terminals inside the big 20pin grey connector behind the carpet at the forward left section of the boot.

    To be 100% sure that it’s the gauge issue triggering the false BRAKE LAMP warning light and not by the wiring, bulb socket, bulb spec, etc, there is a way to disable this warning light by doing something outside of the gauge unit.
    This will disable the BRAKE LAMP warning circuit so for safety reason, I’m not going to tell it here but you probably able to find it out from somewhere else.

    If you carried out this test at the green connector of the gauge unit and if the BRAKE LAMP warning stays on, then it’s 100% confirmed that the issue is inside the gauge unit and you better act sooner rather than later.

    On some cases, when the owner ignored this false BRAKE LAMP warning light, eventually, they started experiencing another warning on the display module such as the door open warning even when both doors were properly shut.

    Then, it’s the matter of when and not if for the fire/smoke to appear.


    In fact, just recently in Japan, another gauge unit developed smoke from behind the steering wheel.
    The owner ignored the false BRAKE LAMP warning and kept driving.
    Then recently, while he was driving, he started to see some smoke.
    It was not enough to catch fire and just burnt part of the circuit board but still, not comfortable seeing smoke inside the cabin especially while driving.


    On NSX Prime, I saw several owners reporting the BRAKE LAMP warning despite the fact that all of the brake light bulbs were fine.
    Some of them decided to disable the warning light.
    Hope they checked everything mentioned above and confirmed that the warning light was caused by something else and not the leakage from the caps on the gauge circuit board.
