Maintenance Sub Items (1-6)

If a maintenance minder indicator does not appear more than 12 months after the display is reset, change the engine oil every year. NOTE: Independent of the maintenance messages in the multi-information display, replace the brake fluid every 3 years. Inspect idle speed every 160,000 miles (256,000 km). Adjust the valves during services A, B, 1, 2, or 3 if they are noisy. Inspect DI+PI fuel system every 3 years or service item B is indicated. Inspect tire condition every 3,100 miles (5,000 km). Number Maintenance Sub Items 1 Inspect tire condition － Check tire inflation and condition at least once per month. 2 Replace air cleaner element － If the vehicle is driven primarily in dusty conditions, replace every 15,000 miles (24,000 km). Replace dust and pollen filter Replace filter whenever airflow from the heating and air conditioning system is less than normal. If the vehicle is driven mostly in urban areas that have high concentrations of soot in the air from industry and from diesel-powered vehicles, replace every 15,000 miles (24,000 km). 3 Replace transmission fluid and clutch fluid (transmission side) Driving in mountainous areas at very low vehicle speeds results in higher transmission temperatures. This requires transmission fluid and clutch fluid (transmission side) change more frequently than recommended by the Maintenance Minder. If the vehicle is regularly driven under these conditions, change the transmission fluid and clutch fluid (transmission side) every 20,000 miles (32,000 km). Use Acura Gear Oil GO-Type 2 for transmission fluid. － Capacity: 4.6 L (4.9 US qt) Use Acura ATF DW-1 for clutch fluid (transmission side). － Capacity: 2.6 L (2.7 US qt) 4 Replace spark plugs Inspect valve clearance (cold) Intake: 0.18－0.22 mm (0.008 in) Exhaust: 0.23－0.27 mm (0.010 in) Inspect Active Exhaust valve function Replace Intake Sound Control － Do the replacement of sound creator. 5 Replace engine coolant Use Acura Long Life Antifreeze/Coolant Type 2, and if necessary add Honda Extreme Cold Weather Antifreeze/Coolant Type 2 (concentrate) as needed for prolonged cold temperatures below -22 °F (-30 °C). Capacity (including expansion tank): 15.5 L (4.09 US gal) 6 Replace twin motor unit fluid Driving in mountainous areas at very low vehicle speeds results in higher level of mechanical (shear) stress to fluid. This requires twin motor unit fluid changes more frequently than recommended by the Maintenance Minder. If the vehicle is regularly driven under these conditions, change the twin motor unit fluid at 7,500 miles (12,000 km), then every 15,000 miles (24,000 km). Use Acura ATF DW-1.

Just a quick tip on checking the car’s coolant level. While straightforward, it can be difficult actually seeing the coolant inside the tank, due to the tank’s opacity.

And for those who don’t know the location of the overflow tank, it is below the left (driver side) engine cover. Just pull it up and it will pop off.

You can try to transilluminate the tank, and that can work, but it is still difficult to see the coolant level.

A better way is to remove the cap and shine a flashlight into the tank. This obviously has to be done when the engine is cold.

The result is a much clearer view of the coolant level.

The twin motor unit fluid is replaced by the maintenance minder’s interval (there isn’t a specific mileage because it is determined by use). The only fluid recommended to be changed based on time is engine oil (once a year, regardless of mileage) and brake fluid (every three years).

First maintenance codes after one year are AB6 . 6 = twin motors

Report from the audio front lines…

1) The factory sub signal has a 50Hz low pass filter on it. Midbass information has to be recovered from the door speaker signals.

2) The amplifier has some kind of protection mode for the door speakers where it lowers the whole system volume upon the detection of sustained mid bass content.

3) The car is actually *too well sealed* to support the airflow requirements of an upsized subwoofer when the windows are up. The seals between the doors and the pillars, and other parts of the interior, are so good that the constant air pressure pushing back on the subwoofer is substantial. This may explain both the tuning of the factory sub, and the protection mode… pushing against high air pressure for sustained durations could cause amplifier overheat.

Stereo shop and system tuner (who have plenty of experience with other Honda/Acura systems including the ELS ones) were scratching their heads for a while until this picture all came together.

NSX is 1kW bat Vs Tesla 100kw

Submitted by Travis Duder

There are several numbers that will identify your NSX.  The most well-known is the VIN (Vehicle Identification Number).  In addition, there are identification numbers for the engine, the three electric motors, and the transmission.  There is also a special Serial Number unique to each car.

VIN

The VIN is located in three areas:  The base of the windshield on the driver’s side, on the floor behind the passenger seat, and on the certification label in the driver’s side door jamb.

The VIN is a unique, standardized code that identifies each vehicle.  The format can vary depending on country.

Using mine as an example, here is what it can tell you:

19U NC1B0 9 H Y 800116

First three characters represents the World Manufacturer Identifier, in this case 19U represents Acura.  In addition, the first character indicates country of manufacture, in this case 1 is the United States.

The next five characters is the vehicle description.  NC1 is the chassis code of the second generation NSX.

The ninth character is a check digit.

The tenth character is the model year.  H=2017, J=2018, K=2019, L=2020.  Note that the letters ‘I’, ‘O’, and ‘Q’ are not used in the VIN.  In addition, the letters ‘U’, ‘Z’ and number ‘0’ are not used for the year digit.

The eleventh character is the plant code.  Y presumably represents the Performance Manufacturing Center.

The last 6 characters is the sequential number.  Canadian market cars start with 8, while US market cars start with 0.  In this case, this is the 116th car built for the Canadian market for model year 2017.

Serial Number

The serial number is located on the rear engine cover.  Every new NSX has a unique serial number based on build order regardless of market, which allows the owner to know exactly when in the build sequence his or her car was built.  So, for example, a serial number of 100 indicates it was the 100th vehicle to be built. Unlike the sequential portion of the VIN, it does not reset each year and does not repeat. The serial number will be continuous until production of the current generation ends. Except for the very early builds, the sequential portion of the VIN and the serial number most likely won’t match.

Engine/Transmission/Motor Numbers

These are located in the following areas:

Certification Label

Located in the driver’s side door jamb, it contains some useful information.  In addition to the VIN, it also shows the vehicle’s build date and paint code.

Paint Codes

• 130R White:  NH-854
• Casino White Pearl:  NH-839P
• Source Silver Metallic:  NH-837M

• Curva Red:  R-559
• Nord Grey Metallic:  G-544M
• Nouvelle Blue Pearl:  B-605P
• Berlina Black:  NH-547

The paint code on the certification label may also have an extra suffix that indicates the interior color:

• Ebony (black):  No suffix
• Red:  X
• Orchid (Seacoast in Canada):  V
• Saddle:  Z
