Customer Questions & Answers
What OBD2 protocols does the KW850 support, and is it compatible with diesel and petrol vehicles manufactured after 2003?
The KW850 supports the main OBD2 protocols: J1859-41.6, J1850-10.4, ISO9141, KWP2000 (ISO 14230) and CAN (ISO 11898). It is compatible with most petrol and light diesel vehicles manufactured from 2003 onwards that comply with the OBD2 standard, but it is always advisable to check the vehicle's OBD regulations before purchase.
What main functions does the KW850 offer, and in which cases is it more advantageous than basic scanners?
The KW850 can read and clear fault codes, reset the check engine light, display live data graphs, interpret more than 3,000 generic codes and check I/M readiness for emissions. Compared with basic scanners, it adds a graphical display and deeper diagnostics, making it useful for workshops and advanced users who need data-flow analysis and live monitoring.
What are the dimensions, weight and exactly what is included in the box when buying the KW850?
The KW850 measures approximately 180 mm x 105 mm x 28 mm and weighs 350 g. Typical box contents include the scanner, a direct-connect OBD2 cable, user manual and, depending on the batch, a carry bag may be included. I recommend checking the seller's specific listing, as accessories may vary.
Does the KW850 require connection to a battery or another power source, or is it powered only through the OBD port?
The KW850 is powered directly through the vehicle's OBD2 port (12 V DC, nominal), with no need for external batteries or additional power. It cannot be used without connecting it to the vehicle with the ignition in the ON position.
What limitations does the KW850 have regarding the types of faults it can detect, and can it display specific data from automatic transmissions or other modules beyond the engine?
The KW850 is focused exclusively on engine system diagnostics under standard OBD2 modes. It does not access transmission-specific modules, ABS, airbags or other proprietary systems. For diagnostics on other control units, more advanced or vehicle-specific multi-brand scanners are required.
Which vehicles is the KW850 OBD2 Scanner compatible with?
It is compatible with most petrol and diesel vehicles manufactured from 2003 that support OBDII protocols, including cars, SUVs and vans. It does not work with hybrid or electric cars.
How do I use the KW850 to diagnose a vehicle?
Connect the KW850 to the vehicle's OBD2 port with the engine running, then use the buttons to navigate the menus to read fault codes, view live data or clear codes and turn off the CHECK ENGINE light.
Can the KW850 help with the emissions test?
Yes, the KW850 includes an emissions test function that shows the vehicle's monitor status and helps prepare for the annual emissions inspection (SMOG CHECK).
Can the KW850 be updated?
Yes, the KW850 allows free lifetime updates via USB connection to a Windows PC to keep the code database and functions up to date.
What is included in the KW850 package?
The package includes the KW850 code reader, OBD2 cable, USB cable for PC connection, user manual and a carry case.
