Winter Storage Note

I put my NSX in winter storage on Nov 15th, 2017. I connected the OEM charger (CTEK) every two weeks to top up the 12 V battery. I started my NSX today after 2 1/2 months of sitting. The EV battery was at about 85% so hadn’t lost much in 2 1/2 months. The car started instantly and ran smoothly. Put it in Sport Plus and the EV battery was fully charged in about 5 minutes. I think once the EV battery is fully charged it will last 6 months. As usual Honda is being conservative recommending a 30 minute run every 90 days.

Night Vision-Headlight adjustment

Night Visibility issue anyone?
I had a chance to drive the car in pitch dark up in Napa last weekend.
I felt the “low beam” headlight pattern was much too low to have safe visibility. Has anyone had an issue?

I got a PDF on alignment and set up to do that procedure & it’s just a pain in the butt. The lights were low by this test but it was a tough measurement.

Then I got smart. I lined up the Tesla & the NSX and compared patterns 60′ across the street. The NSX was significantly lower.
I made a 1/4 turn Clockwise on both and settled for that for now. (It would take about 5/8-3/4 turn to be as high as the Tesla.)
The NSX headlight have a very well defined pattern, or very little “fringe area”.
The NSX is also relatively bumpy ride so that’s why I settled lower than the Tesla for now.
Night visibility is improved, but I would like it a little higher I think.

Easy to do:
A 10 mm socket & 3′ extension.
Marked both adjust with a horizontal reference line toward center line of car.
1/2 turn is a significant change…
Picture & PDF below


[Another Owner feed back: QUOTE=L.L.;1959570]The guide for adjustment with visuals was very helpful. The visibility prior to adjustment was horrible at high speeds. The ideal setting for me is one full turn higher than stock. It probably could go another 1/4 to 1/2 turn before blinding other cars but probably not needed at this point.[/QUOTE]

TPMS Sensor Learning/Re-Learning

According to an Acura Wheel Installation information sheet, the procedure to sync the TPMS sensors to the car is straightforward:

Drive the vehicle for at least 40 seconds at a speed
of 15 mph (24 km/h) or more, and all sensor IDs will
be memorized automatically.

It is unclear at this time how many times this can be repeated, but it has been used to successfully re-learn a new set of wheels by one owner already.  So far, this only applies to the OEM wheels and TPMS sensors.

Roof Console – Radar Detector 12V Wiring access

It is easy to find 12V access in the Roof Console.

Using the “Mirror Tap” product gives easy & very clean access to ignition controlled 12V.

My installation used “Mirror Tap” & “Blend mount” products. I did not have to run wiring along the roof liner and go into the fuse panel.

Roof console module access is:  Roof Console Module 61T6NP2

NSX Wiring diagrams are here:  NSX auto dim mirror wiring connector (1)

NSX mirror wiring is here:  NSX auto dim mirror wiring connector (1)

This photo shows the product info and the installation: 

Every picture tells a story…
Opened the roof console per the instructions above. (Note there is a small cutout in 2 places to CAREFULLY release the light bezels, with a SMALL screwdriver…)
Two bolts (10mm socket) release the module…
The Mirror connector is on the left with the harness end attached to the roof. I removed it, but you don’t need to. (use the mirror side wiring)
The Pin 1, 12V, “lt’s grn” changes to Red on mirror side connector.
The Gnd is pin3… so its Blk

(And yes, it must be NSX magic how 3 wires go to the 5 wire mirror 😉
I chased down the interior wiring… OK, look above for:
NSX auto dim mirror wiring connector (1).pdf
NSX interior lights wiring.pdf

Lots of room up there & easy to feed the Escort connector down the same mirror wire cover in the windshield… (I bought the Escort iX because everyone else bought all the others… A year later, not that impressed 😉

Both the Blend Mount and Mirror Tap make this very easy & clean… JUST REMEMBER TO GET THE 20′ CABLE Mirror Tap… My 15″ install is a little tight… AND the right connector option for your detector!

Note that I did try to find a place to use the suction cup mount that comes with the detector. I do not believe it can be put in the “shaded area so that the GPS receiver can see the sky thru the “shade”…

Also, since the NSX 12V is “switched” so you can leave the unit ‘Auto Off” off, and then it comes on and off with the car.

End of Story…
Mirror Tap is the perfect solution… no wiring; 1 piece of shrink tube; well designed product!
Be sure to order the 20″ version with correct connector for your unit, of course. I got a 15″ version & its length is ok, but more slack would be better.
There are 4 sizes of “inserts” & I used the 2nd smallest for “+” & “-” leads, into the back of the light green mirror plug.
Pin 1 is “+” RED wire & pin 3 is “-” Black…
Pretty much done.

Sidebar Note 1 re GPS reception: My Escort GPS does not seem to receive through the NSX Glass, but it is OK under the center “dotted” mirror section.
Sidebar Note 2 about Blend Mount
Its expensive but perfect for the NSX. They do not provide the magnet & expect you to use that part from the Escort mount you received… I believe this mount allows the GPS to “see” the sky better than through the suction cup.




Identification Numbers

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.


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
  • Valencia Red Pearl:  R-556P
  • 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


How To Update Your Map – Acura Navigation Updates

The following vehicle comes with 10 years of complimentary map updates:

  • 2017-2018 Acura NSX

Your Dash will notify you if there is new SW available.

Your dealer should be able do this, but mine could not complete the task. My dealer tried but the corporate system security would not allow them to download an executable file, so they could not complete the process…

It’s easy to update your Navigation maps if you want to. I went home and followed the instructions and updated my Mapping.

Instruction tell you:

” To perform these updates you will need the following:
 16 GB USB drive
 High-speed Internet connection
 Up to 4 hours of time

(I found DL, & install time to be just a few minutes each. It does NOT take 4 hours! Probably 30-45 minutes running back and forth between your computer and the car with a “memory stick”… you can use either USB port. I’m sure my 2nd time will take 15 minutes…)

The following link will take you to the instructions to do it.

This is what my Nov 2017 updated SW shows:
