Nonda zus obd-ii smart vehicle health monitor review – the gadgeteer gas leak smell


The ZUS Smart Vehicle Health Monitor (SVHM) comes in a fairly standard printed cardboard box. The front and rear of the box lists the main features of the device, which includes engine health monitor, EzzySaver Dashboard, mileage log and Safety Center.

The ZUS OBD-II SVHM is an unobtrusive black plastic adapter. Its small size is useful if the OBD-II connection is towards the front underside of the dash. The front has a gently curving face with the stylized “a” logo of the Nonda company. Below the logo are three LED that indicate the status of the automobile and Bluetooth connections. Honestly, the adapter is better looking than it needs to be considering it will spend most of the time plugged in underneath the driver’s front seat. Installation is easy; the adapter fits firmly into my car’s connector so that it will not fall out unintentionally. Removal only requires a simple tug.

The adapter only works with the Nonda app for iPhone or Android. The app is a common control and user interface for the entire Zus Connected Car System. It not only controls the SMHV but smart car chargers, smart tire safety monitor, smart backup camera, key finder, and car audio adapter produced and sold by Nonda.

The app requires a login for use. This functionality allows Nonda to determine if you have a mileage log subscription or are operating on the free version. A login also permits Nonda to upload your mileage to a server so that it can be viewed on the web. It doesn’t appear that the program can be used without a login, although if you prefer not to give out your information, a mailinator address will work just fine. If you don’t have one or more of these items the welcome screen also takes you to the website to purchase an adapter.

The software has some permission prerequisites to enable geolocation services. The explanation below implies that the Zus system will provide an option to find the car after parking. However, I found that this is not the case. The smart car finding function is only available with the smart car charger adapter. The app does not require location awareness for the functions that the smart vehicle health monitor provides.

Once connected and paired the app shows the info in the image above. Despite the claims that the app includes an upgrade to the EzzySaver function, there is, in fact, no indication of the instantaneous fuel consumption. Furthermore, the only record of the values captured are the speed, revs, turbo pressure, load and coolant temp. None of the other 235 sensor values supported by the ECU standard are available, and no logs of data are available either. Without logs, it is necessary to consult the data while driving, but i t is difficult to see the small text and graph on the screen while driving.

The Safety center performs a number of checks but does not provide any indication of the measured results. Many of these checks, if not all of them are either true or false. I don’t believe the SVHM can predict when an item may malfunction simply by the car’s ECU returning a working or failed indication. So, I’m not really sure what this safety check is doing. The results of the check came back fine on my car. The manufacturer’s website includes a couple of videos where the ECU returned an out of tolerance EVAP condition because the fuel cap was left off. Unfortunately, my car doesn’t include a gas cap (it has a capless gas tank fuel-filler) so I couldn’t test this feature.

It seems that keeping the device in the OBD-II Data connector may be convenient, but constant installation may drain the car’s battery. Also, keeping this installed precludes using other OBD-II items, like you may get from your auto insurance provider. What I like
