Around march, a cluster from France arrived with the famous "permanent brake system warning" and about 70.000 km of roads travelled. Using the tester, the issue was confirmed quickly. RPM values were ~500 too high, speed about 10 km/h too much. Illumination bulbs were darkened but all working -...

Another radio with intermittent sound output arrived at my desk. It was previously repaired in 2008 but not exactly in top quality. state of repairs 2008 Nevertheless it played fine for 5-20 minutes when it suddenly dropped silent. Different from a previous case regarding a USDM radio the...

While working on the radio from France the unit from Another radio question came in. Just as described, all inputs and functions were fine but the speaker output was intermittent and worked only for a few seconds before cutting in and out randomly. Since there was obvious damage by leaking...

One of my toughest work on an NSX radio was completed as of this morning. The French radio came in with multiple issues at the same time: CD port non-operational Aggressive scratching noise when turning the volume knob A loose volume knob Permanent knocking sound even with zero volume...

A German radio from a 1992 NSX arrived in the worst possible state - it wasn't turning on. So far only half of the radios in this state could be saved since the acid damage can be quite severe and there aren't replacements for all of the parts in the radio. If proprietary chips are affected it's...

A direct message via the the German Motortalk forum reached me. A distressed NSX driver was reporting about trouble with his radio head unit. The volume was unusually low, noise was generated when changing the volume and another repair approach had already failed. We talked a bit over the...

By far the worst condition CCU arrived a few weeks ago. The PCB was probably kept in a damages state for quite some time and the the acid turned the PCB silk screen into a dark black color. Here are some more details of the affected areas: Besides the capacitors, several...

One more Swiss radio arrived with a strange phase-like sound and a wobbly volume knob but otherwise fully working. Looking at the PCB after removal of the capacitors, the damage wasn't too severe but surprisingly strong around the smaller E818: With the contaminated areas cleaned by a...

A seemingly normal Climate Control Unit (CCU) with a fan working only in the max and off position came in from Switzerland. The issue was confirmed in my own NSX with the self test not showing any issues just the fan not working as it should. This usually points towards capacitor issues but when...

Just in time for Christmas a huge package from the Netherlands arrived at my door, containing a whole set of NSX electronics waiting for recap and potentially repair. One of the first items on the list were the speaker amplifiers. front left amplifier front right amplifier footwell...

A fellow NSX driver approached me after fixing all three of his amplifiers reporting issues with his radio. It worked but when listening to stations they were distorted and he mostly used it together with a CD changer adapter. The unit arrived last week, with an interesting modification to...

One more French NSX owner had issues with his original speakers - which led him to turn the active speakers into passive ones, using a separate amplifier a few years ago. he removed amplifiers have been waiting for a capacitor replacement and repair since then. The assumption that the PCBs...

Since one of the three amplifiers received couldn't be repaired, the owner bought a replacement unit from an Australian seller. The state was described as "working" - which was technically correct but only for about ten minutes and with reduced volume. From a first picture it could be seen...

The radio that came with the three amplifiers was in a pretty bad shape. Capacitor leakage had even penetrated to the bottom of the board. The design of the 1992 EU radio utilizes several large capacitors on the lower PCB that can cause significant issues when leaking. Since the car spent about...

A french NSX owner sent me his Bose speaker amplifiers (and the radio - but we'll come to that in a separate thread) for repair. The car has been left in a garage for a considerable amount of time and the audio system was non-functional as not even the head unit would turn on. The PCBs were...

It's been a few months since the first Gauge Cluster Tester was finalized. It has served me well during capacitor replacement but it's also limited in certain ways. A significant amount of manual work is required for every build (drilling, printing, cutting, etc.) and only six of the many...

Failing capacitors at the gauge cluster of the NSX is a serious topic. First signs are a non-accurate speed indication or a permanently lit brake light warning even though bulbs and wiring are OK. The leaking acid near the warning indicator circuit can cause a short and even potentially lead...

Even though working-at-home, home-schooling and home-kindergarten doesn't leave much spare time it's important to have a bit of a hobby for a change. Since I'm working through the ECUs related to capacitor replacement it's now the gauge cluster's turn. Replacing its capacitors pro-actively...

Since a few days my instrument cluster is out of the car, primarily for replacing the capacitors to prevent the popular cluster fire issue. To avoid any issues before installing it into the car a small test bench is built to check lamps, indicators and the two main meters. Drew helped with...

For a micro-controller project (providing FM and DAB+ radio inside the original NSX radio, keeping all buttons and knobs fully functional) I need an NSX radio. A defect or broken radio would be fine, too (only outer shell, front panel, buttons and knobs need to be OK).

Acura NSX Owner Manual - Single PDFs Many used NSX buyers did not receive a manual with their car. Acura USA offers manuals for download. Unfortunately the storage format of some of the older manuals (many files to jump around) may cause issues with certain PDF readers both during offline and...

Dear NSX Prime, After many many years I finally signed my contract for a used NSX here in Japan. During the chase I used the Wiki extensively and would like to contribute. Unfortunately I can't log in, it seems. Is a special request needed to be able to edit the Wiki? PS: Sorry in case the...
