--> Why Do you Choose FOXWELL NT301 Plus ? --- Easiest , Cost-effective and Accurate Diagnosis

  • In my case I purchased it as I knew I may be facing an expensive repair if the diagnostics took me down that path. Instead the repair required was a lot less than anticipated. The value of the obd2 reader was it prepared me for the worse case scenario that luckily wasn't required.
  • So for an average vehicle owner like myself, it provides an insight as to why a check engine light comes on and to plan the repair informed. It also was helpful to know my battery was dead, so I didn't just jump start it, and then get stranded somewhere.

Since I Used the Diagnostic Device, it brought me More Surprises and found that it was a Treasure, Exactly what I Needed. Such As

  1. Easy to Use ( Plug&Play) -- Plug it in and follow the promts. It gives a description of what might set off certain codes and it has the ability to erase codes. Support EVAP Test.
  2. Reset a Check Engine Light -- When plugged in the Foxwell unit and it checked my car and reset my CEL in minutes. It allowed me to rea code and test engine light at home.
  3. Pass S-m-o-g Check(One-Key I/M Readiness) --The e-mi-ssions light keeps on coming on even with a new gas cap fully tightened. It has also been checked by a dealer and a highly recommended independent mechanic shop in my area. Everyone tells me the e-mi-ssions system is fine including the state e-mi-ssions inspector. When the I/M light came on again i bought this unit, and we were able to verify the I/M issue again and clear the message immediately.
  4. Battery Health Checker -- Car Scanner Can read details of battery conditions on many levels, such as provide the basic voltage, measured cranking amps, internal resistance, state of charge, and battery health information. Can Test the starting(cranking) and charging system.

Use this battery tester to check if the generator provides sufficient power to the vehicle electrical system, and if the battery can hold the charge.

More data are also included: CCA value/rating, voltage, internal resistance, state of health (SOH), and state of charge.

State of health (SoH) is a figure of merit of the condition of a battery (or a cell, or a battery pack), compared to its ideal conditions.


Plug and play--input the rated battery capacity, NT301 Plus will start analyzing the battery's CCA value, charge (%), voltage (v), rated CCA, battery healthy (%) and display the test result on screen within seconds.

  • GOOD BATTERY -- Good Condition
  • GOOD-RECHARGE -- The battery is in good condition but low current, be need to fully charge and return it
  • CHARGE & RETEST -- Failure to fully charge the battery before testing may result in inaccurate results. If you still get the CHARGE & RETEST message after you fully charge the battery, replace it.
  • REPLACE BATTERY -- The battery is almost dead,or the connection is poor. Replace the battery and retest, or disconnect the battery cables and retest the battery using the out-of-vehicle test before replacing it.
