Description

KONNWEI KW902: A small Bluetooth OBD2 adapter based on the ELM327 command set. It plugs into the 16-pin OBD2 port and turns an Android or iOS phone into an OBD2 scanner with a compatible app (KONNWEI recommends the free MAXOBD app; third-party apps such as "Car Scanner" also work). It has low-power sleep mode and reads engine data from 12V petrol and diesel cars.

Product Functions (with a compatible app):
• Read and clear engine trouble codes, turn off the Check Engine Light
• Live data: vehicle speed, RPM, fuel consumption, coolant temperature, fuel pressure, engine load, throttle position, intake manifold pressure, intake air temperature, timing advance, MAF, fuel level, barometric pressure, EVAP vapour pressure, fuel trim
• I/M readiness, freeze frame, O2 sensor test, vehicle information

Range of Diagnose:
Works on 1996 and newer OBD2 / EOBD compliant 12V petrol and diesel cars and light trucks (US 1996+, EU petrol 2001+ / diesel 2004+, Asian vehicles) with the 16-pin diagnostic connector. Supports all OBD2 protocols: CAN, KWP2000, ISO 9141-2, J1850 PWM and J1850 VPW.

Technical specification:
Connection: Bluetooth 5.0 (hardware 1.5), Android and iOS
Chip: ELM327 compatible (IC25K80)
Input voltage: 12V (from the vehicle)
Operating temperature: -10 to 60°C (14 to 140°F)
Size: 4.5 × 5.7 × 2.5 cm
In the box: KW902, user manual.
The user manual is available from KONNWEI (konnwei.com, Support section).

Compatibility disclosure

Bluetooth ELM327-type OBD2 adapter. Generic OBD2 functions only, through a compatible app (KONNWEI MAXOBD app or third-party ELM327 apps such as Car Scanner – not part of the adapter). Available functions and live-data parameters depend on the app. Generic OBD2 / EOBD engine and emission diagnostics on 12 V cars and light trucks with the 16-pin connector (KONNWEI states: American cars after 1999, European cars after 2002, Japanese and Korean cars after 2007, Chinese cars after 2009). The car must be OBD2 / EOBD compliant – check the "Vehicle Emission Control Information" sticker under the hood for "OBD II Certified"; cars with the private Japanese JOBD protocol (e.g. some Nissan units) are not supported. KONNWEI states it does not work with SsangYong, Lada / VAZ / UAZ, Opel Corsa C 2004 1.3 CDTI, Citroën C4 and C5, Renault Logan and Megane. The KONNWEI manuals give only "all 1996 and newer vehicles sold in the USA". Engine system only – no ABS, SRS, transmission, body or service functions. Not supported: OBD-I vehicles, motorcycles, 24 V trucks and buses (J1939), hybrid / electric drive systems.
