This one is possibly the most simple and accurate of the bunch I have tried so far. The setup is like “take it out of the box and use it”, it really was that simple. The codes were easy to understand and the book and info you can get from their website made the whole thing a no-brainer.

Top Reasons to Choose NL101
  • Live data show in Graph, the data are straightforward to know.
  • Battery check, it is seldom to have in the same product.
  • Multi-Languages, English, Spanish, French, Deutsch, Italian, Russian, Portuguese, Finnish etc.
  • A free protection case, you don’t need to pay for it, but most products on the market need to, that is the other product doesn’t have.
  • NL101 can quickly check the battery health of the vehicle, read the current battery value, and give a level 6 battery warning.
 NEXAS NL101 OBD II Modes of Operation
  • Mode 01 – Identifies the Powertrain information and shows current data available to the scan tool. This data includes: DTC set, status of on-board tests, and vehicle data such as engine RPM, temperatures, ignition advance, speed, air flow rates, and closed loop status for fuel system.
  • Mode 02 – Displays Freeze Frame data. Same data as in mode 1,but it was captured and stored when a malfunction occurred and a DTC was set. Some of the PIDs for mode one are not implemented in this mode.
  • Mode 03 – Displays the type of powertrain or emission related DTCs stored by a 5 digit code identifying the faults. There may be more than one response message if there are more trouble codes than will fit in the data bytes of the response message, or if there are more than one ECU computer responding.
  • Mode 04 – Used to clear DTCs and Freeze Frame data. This clears all diagnostic trouble codes that may be set including freeze frame data and readiness monitors.
  • Mode 05 – Displays oxygen sensor test results. This mode displays the oxygen sensor monitor screen and the test results gathered about the oxygen sensor. There are ten numbers available for diagnostics: 01) Rich-to-Lean O2 sensor threshold voltage. 02) Lean-to-Rich O2 sensor threshold voltage. 03) Low sensor voltage threshold for switch time measurement. 04) High sensor voltage threshold for switch time measurement. 05) Rich-to-Lean switch time in ms. 06) Lean-to-Rich switch time in ms. 07) Minimum voltage for test. 08) Maximum voltage for test. 09) Time between voltage transitions in ms.
  • Mode 06 – Non-continuously Monitored Systems test results. There are typically a minimum value, a maximum value, and a current value for each non-continuous monitor. This data is optional, and it is defined by a given vehicle maker if it’s used.
  • Mode 07 – A request for DTCs (pending) from Continuously Monitored Systems after a single driving cycle has been performed to determine if repair has fixed a problem. This is used by service technicians to verify repair was performed properly and after clearing diagnostic trouble codes.
  • Mode 08 – This special Control Mode requests control of the on-board system, test, or component bi-directionally (where applicable). This mode is manufacturer specific.
  • Mode 09 – Reports vehicle information. This information includes vehicle VIN number and calibration information stored in the vehicle ECUs.
  • Mode 10 – Requests Emission-Related Diagnostic Trouble Codes with Permanent Status. This mode is required for all emissions-related DTCs. The presence of permanent DTCs at an inspection without the MIL illuminated is an indication that a proper repair was not verified by the on-board monitoring system.

  • Question: does this unit have the ability to clear oil life indicator
    Answer: This like many other Scanners, will turn off the check engine light. And tell you what may be wrong with your car. But if your car is equipped with a oil life indicator light, it’s for a reason. The oil is the life of a car. How it works and when to change it is very important on your auto. Instead of turning the light off, you should check why it came on in the first place. Before resetting the light, or turning it off…. This is a great scan tool, for working on many cars.
  • Question: how long is the cord?
    Answer: The length of the cord is 31 inches, adding in the lengths of the unit and plug gives an overall length of 38 in.
