Please check your cable end or/and USB plug on instrument for possible damage first.
Ensure the OBD power supply is fully inserted into the car OBD connection

The Mini USB connector has been on the market for a long time.  Many cell phones were using them until the EU required a standard jack on all phones that became known as micro USB. If you have a GPS in your car, or a portable hard drive, chances are, it is using a mini USB for sturdiness.

Although it is sturdy, with time or by accident, the connector can be damages by dust, contamination (like calcium, road salt), or simply get "stretched" to the point it will not stay in place anymore.

This guide will help you understand how they work so you can keep USB connector in good working order.Please note, damaged, pulled, stretched cable or salt corroded contact are not covered under normal warranty.Any damaged mini USB cables can seldom be fixed by most electronics technicians, please refer to the section   How to fix any mini USB Cables ( for technician and DIY )

Description of the Mini USB

Mini USB connectors use 5 pins to make contact from the cable to the equipment.

Some pins are used to power the device, other are used to communicate with it.

The connector has a specific shape that make it impossible to plug it in backwards



The basic shape of the connector ensure proper friction to maintain them together.

In the image below you can see both parts of the connection system.
The cable on the bottom has a specific width ( blue arrows) and height (orange arrows)

The device USB port must have the same spec inside in order to stay together with the cables outside.

Mechanical Problem

If a device gets thrown around, dropped, plug in and out countless times, it will eventually need to be replaced or repaired.

As mention earlier, the connectors use friction in order to stay connected together.

If the connector gets forced up and down, or left and right, the inside section will eventually get 'stretched'

This situation will lead the device to turn OFF and ON, or will have trouble keeping the communication on when connected to a computer.

Mini USB ends are built sturdy, but are not made to withstand impacts. ( none of the USB are)

Contact Problem

TripLogik uses industrial grade USB connector in it's instruments.
With a plating of 30 Microns of gold, it is well over 30 times the normal consumer grade of 0.7 Micron 

Along with a stainless steel outer shell, TripLogik factory treats all connectors with DeoxIT to further protect it against harsh environment inside a car.

If you see the connections don't look clean, you might have to de-oxidize the contacts. please refer tot he Suggested cleaning section

Protection and maintenance

Although the contacts inside the connectors are gold plated on each side, TripLogik factory treats every instrument connector and cables with a special protection.

This chemical not only acts as a contamination barrier, but is a light lubricant too.
Like any anti-corrosion, it must be maintained every once in a while.

If you suspect a problem with any USB connector, first look inside the connector and look at the contact pins ( with a magnifier if you need to)

If they look dull or discolored, unlike gold color, the connector is probably contaminated.

What to do if you drop the instrument or the cable end in the water or show 

No Blowing in the connector to dry it will not work...
What ever you do, DO NOT PLUG IT ANYWHERE.

The water my not have entered the instrument, but the USB connector is now contaminated with minerals. Most probably calcium
Consider this :
Calcium + water  = good electric conduction
Water with salt between metal plates  + Electricity  = electroplating conditions 

In other words 
When electricity will flow through the contacts, to power the device, ( and the device may power up)  It will accelerate the corrosion process, ruining the cable and the instrument connector at the same time. 

Contact will eventually look dull and discolored, and may even start to disappear because the corrosion is amplified by the electric current, thanks to the minerals in the water.


Don't damage other equipment too 

If you take this contaminated instrument to another cable, this cable runs the change of getting contaminated too.
This can lead to other equipment getting their connector damaged too.

Suggested cleaning 

We recommend using a product called Deoxit D5

This chemical is specially formulated to de-oxidize contact like gold, tin, copper etc.

It is non-conductive and nonflammable, so it is safe to use with this type of electronic device.

DeoxIT can be ordered trough the Triplogik webstore , or from electronic repair shops

If you would like to order a 2oz tube, Please open a service ticket to contact tech support

Purchase from our web store here : Buy Deoxit now  


What you need:


Magnifying class
Dry paper towel



1)  Keep the connector facing UP 

2)  Put a drop inside the USB cable  ( no need to fill it, just ensure all of the pins are soaked)

3)  while holding the cable facing up, plug in the device in and keep the connector this way to prevent the liquid from dripping inside the device

4)  Plug and unplug 5 to 10 times in this position

5)  Have a closer look at the contact in the cable and the device to see if they improved

6)  Repeat if required


We do not recommend using regular electronic contact cleaners unless you only use it on the cable end.

Standard cleaner products contain alcohol that also contains water, therefore making it conductive.

If contact cleaner gets inside the device, it could damaged the electronics and leave residues that can promote corrosion everywhere else in the instrument.

Pure Deoxit is non conductive 


This guide is a generic repair solution not specific to the logger device and it's cables.
We recommend any repairs be performed performed by a technician.

Although we do not recommend fixing the cables yourself, some user are able DIY.

TripLogik will not take any direct or indirect responsibility for any repair done by the user or a third party or unauthorized TripLogik technician.

This procedure is done at your own risk, and is not covered by any warranty.

If you are uncomfortable with this procedure, we suggest you purchase a new cable.
