Hello what does the code P1035 mean
What does the OBD2 error code P1035 mean?
The FOXWELL NT301 manual provides a built-in DTC GUIDE and a HELP key to look up code definitions directly on the device. If the code appears with a "?" symbol, you can press the HELP button (labeled 'N' on the device diagram) to get a guide for possible car issues.
Regarding the specific code P1035: This is typically a manufacturer-specific code rather than a generic global OBD2 code. For many vehicles (such as Volkswagen, Audi, or Toyota), it often relates to the Oxygen (O2) Sensor Heater Control Circuit or a Variable Valve Timing (VVT) sensor issue. However, because definitions vary by vehicle make and year, you should use the NT301's built-in lookup function or check your specific vehicle's service manual for the most accurate interpretation.

Very good all the information
Muy buena toda la información
I brought one of these things for 12/2016 BT 50 what a waste of money the thing won’t leave the startup screen now lives in the bin never by FOXWELL brand again Wally
How do I fix a Foxwell NT301 that is stuck on the startup screen?
If your Foxwell NT301 is stuck on the startup screen, it may be experiencing a firmware freeze or a power delivery issue from the vehicle's OBDII port. Before discarding the unit, you can attempt to recover it using the following steps:

Can I use my code reader on a 24volt truck
Can I use the Foxwell NT301 code reader on a 24-volt truck?
No, the Foxwell NT301 is designed specifically for standard passenger vehicles and light trucks that use a 12-volt electrical system. It is not compatible with 24-volt systems commonly found in heavy-duty trucks or commercial machinery.
Attempting to use a 12V OBD2 scanner on a 24V system can potentially damage the device or the vehicle's diagnostic port. For 24V vehicles, you would typically need a heavy-duty scanner that supports J1939 or J1708 protocols.

I have a FOXWELL NT 301 does it work for all cars?
Jag har en FOXWELL NT 301 fungerar den till alla bilar?
Jag har en FOXWELL NT 301 fungerar den till alla bilar?
Does the FOXWELL NT301 work for all cars?
The FOXWELL NT301 is designed to work with most vehicles that are compliant with OBDII/EOBD standards. Generally, this includes:
It supports all 10 OBDII test modes and works with protocols such as CAN, J1850 PWM, J1850 VPW, ISO9141, and KWP2000. However, it is primarily a powertrain (engine) code reader; it may not support advanced diagnostics for non-OBDII systems like ABS, Airbags, or Transmission on all makes. For specific compatibility with your vehicle's year and model, you can verify if your car has a 16-pin OBDII port and an emissions label stating OBDII compliance.

Can you reprogramme batteries with this scan tool
Can the Foxwell NT301 reprogram or register batteries?
No, the Foxwell NT301 cannot reprogram or register new batteries. Based on the product manual and applicable functions, the NT301 is a dedicated OBDII/EOBD code reader designed for engine diagnostics.
Its primary functions include:
Battery registration (BMS reset) is a service function typically found on higher-end diagnostic tablets (such as the Foxwell NT644 or NT710 series) rather than entry-level code readers like the NT301.

Esse escaner funciona na s10 2.2 97
Does the Foxwell NT301 scanner work on a 1997 Chevrolet S10 2.2?
The Foxwell NT301 is designed to work with vehicles that are OBDII/EOBD compliant. Generally, this includes most cars sold in the US from 1996 onwards.
However, compatibility for a 1997 Chevrolet S10 2.2 can be uncertain depending on the specific region where the vehicle was manufactured (for example, some models in the Brazilian market did not adopt the full OBDII standard until later years). To confirm if your vehicle is compatible, please check for the following:
If your 1997 S10 uses the older ALDL (OBD1) system, the NT301 will not be compatible without a specific adapter, and even then, it may not communicate with the ECU as it is primarily an OBDII/EOBD tool.
