If you mean how to investigate a gauge panel fault, the answer is relatively simple. You'll need to purchase a Honda Shop Manual and spend several hrs reading about the B-Can and F-Can system that controls the Multiplex Integrated Control System. If it sounds a bit complex, you're right. The MICS covers about 50 pages of the hefty manual.

However, to Honda's credit it does include a method of diagnostics that does not require the Honda Diagnostic System (HDS). System appears similar to OBD1 system and uses flashing lights to display DTC's. Other DTC's are displayed by the odometer LCD. There are 4-pages of DTC's.

I bought my manual from helminc.com, but there are other sources on www. I think I paid about $100, and worth every penny.

good luck

I have a gas gauge that is malfunctioning and was attempting to determine if it is the needle itself or something on up the line. I there a method to check the instrument panel for a faulty needle?

For earlier models, you can disconnect the connector to the fuel level sensor in the trunk. Gas gauge needle should fall to zero. If this happens, the gauge is probably OK, and fuel level sensor is failing.

If gauge is sticking or giving erroneous results, some have fixed by adding Techron fuel additive. It reportedly cleans the sulfur deposits off the variable resistor surface that sometimes causes the problem.

good luck
