Introduction
Failure of the Climate Control Unit (CCU) is a common fault, affecting nearly any NSX. In almost any case, capacitor replacement and track repair will fix all issues. Depending on the state of the PCB, further damage to other components can happen, though.

Diagnostic - Transistor Issues
The following error cases and ways of repairing have been identified so far. These faults can be caused by major acid leakage affecting nearby transistors.

Introduction
The NSX Gauge Cluster provides a large number of functions and displays, resulting in roughly 60 pins across two green connectors. Testing all of them manually is a error-prone task, requires special equipment and takes a lot of time. To speed things up, it helps to have a tester that provides all of these functions in a compact way and utilizing the original connectors.

Requirements
A simple user interface. Usage of the original connectors. Adaptable for multiple ...

Introduction
The Gauge Cluster suffers from ageing capacitors as many ECUs in the NSX. Leaking capacitors at the gauge cluster is a serious issue. Acid near the warning indicator circuit causes shorts and potentially lead to a fire. Same as with the other capacitor issues, a replacement should be considered before the unit fails.

Diagnostic
First signs are a non-accurate speed indication or a permanently lit brake light warning even though bulbs and wiring are OK. ...

Introduction

Around the 100.000 to 150.000 km range the first illumination and indicator bulbs in the Gauge Cluster start to fail. Replacing individual bulbs isn't economical considering the effort to get the cluster out of the car. Replacing all bulbs is the preferred route (except for AT vehicles - which will be explained below).

JDM 1997 AT Cluster

All bulbs can be replaced without disassembling the cluster, except ...

Introduction
The NSX's Gauge Cluster is a good example for a nice and simple design - it features a symmetric layout with one large dial on each side, accompanied by two small dials. These main functionalities are realized:

• Speed dial (country specific labeling and range)
• Tachometer (model specific range)
• Temperature, oil pressure and fuel gauge
• Shift indicator (AT only)
• ~30 indicator lights (some model and country specific)

Variations and Build ...
