Introduction Failure of the NSX active speakers is a common fault, especially for the early build years. The modules are class-D switching amplifiers with a MOS-FET driver bridge. The output driver relies on the fact that two opposing transistors are never conducting at the same time. If this happens, a direct connection between GND and VBAT is created, with fatal consequences. Diagnostic Typical failure is due to capacitor leakage. The fluid travels underneath ...

Introduction The Supplementary Restrain System (SRS) ECU suffers from ageing capacitors the same way as many other ECUs in the NSX. Two things makes it a special issue: The SRS is a safety device and a permanently lit warning light means failing the regular vehicle checks in most countries. Especially the first generation ECUs (cars with only a driver's Airbag) tend to fail by shorting an important MOS-FET inside the housing which complicates repairs. Diagnostic Due ...
