NEXAS Check Engine Light Obd2 Scanner Car Diagnostic Machine For All Cars

The NL101 is a practical OBD2/EOBD diagnostic tool designed for vehicle owners, DIY users and entry-level automotive technicians who want more than a basic fault-code reader.

It combines 10-mode OBDII diagnostics, Check Engine Light diagnosis, Battery Health Check, Live Data, Graphical Data Display, Freeze Frame, O2 Sensor Testing, EVAP Testing and I/M Readiness in one dedicated handheld scanner. It is designed to help you understand what is happening with your vehicle before replacing parts or paying for unnecessary diagnostic work.

COMPLETE OBDII / EOBD DIAGNOSTICS

Go Beyond Reading and Clearing Fault Codes

NL101 supports the full range of standard OBDII diagnostic modes for supported vehicles.

It can read and erase stored and pending trouble codes, display code definitions, check the Check Engine Light status and retrieve vehicle information including VIN, CIN and CVN.

This allows you to identify the system reporting a fault and investigate the problem before deciding what needs to be repaired.

10 OBDII TEST MODES

NL101 supports 10 OBDII modes, covering the key functions required for engine and emissions-related diagnosis:

Read Codes Erase Codes I/M Readiness Live Data Freeze Frame O2 Sensor Test On-Board Monitor Test EVAP System Test Vehicle Information Permanent/Pending Code Diagnosis

The exact tests and data available depend on the vehicle's OBD system and manufacturer configuration.

TROUBLESHOOTING TIPS - UNDERSTAND THE DATA

Don't Just Look at the Numbers

One of the useful features of NL101 is its built-in Troubleshooting Tips.

When viewing supported Live Data parameters, the tool can provide additional information explaining what the parameter means. This helps users understand the data they are seeing and gives technicians a useful starting point when investigating an abnormal reading.

Instead of simply displaying a value such as engine RPM, coolant temperature or fuel-related data, NL101 helps you understand what the selected parameter represents.

GRAPHICAL LIVE DATA

See Vehicle Data Change in Real Time

NL101 displays the PCM Live Data Stream and can present selected data in live graphical form.

Graphing makes it easier to observe changes in sensor and engine parameters while the vehicle is running. This can be useful when checking intermittent problems, monitoring sensor behaviour or comparing vehicle data before and after a repair.

FREEZE FRAME DATA

See What Was Happening When the Fault Occurred

When an emissions-related fault is detected, the vehicle ECU may store a snapshot of operating conditions at the time the fault was recorded.

NL101 can display available Freeze Frame Data, which may include information such as engine RPM, vehicle speed, engine load, coolant temperature, fuel trim and other operating parameters.

This gives you additional information beyond the fault code itself and can help narrow down the conditions under which the problem occurred.

BATTERY HEALTH CHECK

Check Your Battery Before It Leaves You Stranded

NL101 also includes a built-in Battery Health Check, allowing you to quickly check the vehicle battery condition and current battery voltage.

The tool provides battery voltage warnings to help identify a battery that may be too low and could cause difficult starting or require further inspection.

This makes NL101 useful not only when the Check Engine Light appears, but also when a vehicle has starting problems, low-voltage symptoms or has recently had battery-related work performed.

O2 SENSOR & ON-BOARD MONITOR TEST

NL101 can retrieve available O2 Sensor Test results and On-Board Monitor Test results from supported vehicles.

These functions provide additional information about the vehicle's emissions-related monitoring systems and can be useful when investigating Check Engine Light conditions.

Not every vehicle supports every available OBDII test, so the displayed functions and test results will vary according to the vehicle.

EVAP SYSTEM TEST

For supported vehicles, NL101 can initiate the vehicle's available EVAP system diagnostic test through the OBD system.

The tool communicates with the vehicle's onboard computer to request the test; it does not physically perform an EVAP leak test itself.

ALL MAJOR OBDII PROTOCOLS

NL101 supports the major OBDII communication protocols:

CAN J1850 PWM J1850 VPW ISO9141 KWP2000

This allows broad compatibility across supported European, American and Asian OBDII vehicles.

NEXAS specifies compatibility with OBDII/CAN cars, minivans and light-duty vehicles from 1996 onwards, subject to the vehicle's actual OBDII compliance and configuration.

SIMPLE WIRED OPERATION

NL101 is a dedicated handheld diagnostic scanner. There is no phone, app or Bluetooth connection required.

Simply connect the OBD cable to the vehicle's diagnostic socket and use the built-in colour display and physical controls to navigate the diagnostic functions.

The dedicated design makes it straightforward for users who prefer a reliable plug-in diagnostic tool rather than relying on a smartphone application.

MULTILINGUAL DIAGNOSTIC INFORMATION

The NL101 supports a range of menu and diagnostic languages, including English, Spanish, French, German, Italian, Russian, Portuguese and Finnish, depending on the installed software version.

DTC definitions are also displayed directly on the scanner, helping users understand fault codes without needing to search for every code separately.

IDEAL FOR EVERYDAY VEHICLE CHECKS

NL101 is particularly useful when you want to:

Check a Check Engine Light Read and Clear Fault Codes Investigate Pending Codes Monitor Live Engine Data Check Battery Voltage Review Freeze Frame Data Check O2 Sensor Results Check I/M Readiness Inspect a Used Vehicle Verify a Repair

For used-car inspections, the I/M Readiness and diagnostic functions can provide useful information about whether supported emissions monitors have completed their required tests. This can also be useful after a battery has been disconnected or diagnostic codes have been cleared, when readiness monitors may need to complete a new drive cycle.

BUILT FOR PRACTICAL DIAGNOSIS

The NEXAS NL101 is not designed to replace a professional full-system workshop scanner.

Instead, it focuses on doing standard OBDII engine and emissions diagnostics well, while adding useful features such as Battery Health Check, Troubleshooting Tips, Graphical Live Data and Freeze Frame Data.

For drivers and technicians who mainly need to diagnose Check Engine problems, understand vehicle data and monitor basic vehicle health, NL101 provides a practical diagnostic solution without the complexity of a larger multi-system scan tool.

IMPORTANT COMPATIBILITY INFORMATION

NL101 is an OBDII/EOBD diagnostic scanner, not a full-system diagnostic tool.

It primarily communicates with the vehicle's OBDII-compliant systems and should not be expected to provide the same coverage as a full-system scanner for modules such as ABS, SRS, BCM or other manufacturer-specific systems.

Actual functions and available data vary by vehicle make, model, year, engine and ECU configuration.

Please confirm your vehicle's OBDII compatibility before purchase
