What the MaxiDiag MD801 does

The MaxiDiag MD801 is a handheld scan tool for professional technicians and serious DIY owners who need full-system diagnostics on one device. It reads and clears fault codes from engine, transmission, airbag and ABS modules across a wide range of US, Asian and European vehicles. The unit also turns off the related warning lights and displays DTC definitions directly on its screen.

OBD coverage and practical limits

Global OBD I and OBD II coverage is supported, including all nine J1979 test modes such as live data, freeze frame, I/M readiness, O2 monitor test and component test. Enhanced Mode 6 data is available for deeper emissions analysis. CAN protocol is enabled for faster communication with newer ECUs. Coverage years differ by manufacturer and stop at 2008, so vehicles built after that date are not supported.

Upgrade path and when it matters

The MD801 replaces basic code readers that only access generic OBD II engine codes and cannot reach transmission, airbag or ABS systems. It adds manufacturer-specific code reading, data graphing, ECU information retrieval and off-vehicle review via memory backup. The jump is worth it when you need to diagnose safety systems or ABS faults on supported pre-2008 models and want software upgrades via internet without buying a new tool.

Questions about this item

Should I choose the MD801 or a basic code reader for my 1990 VW?

The MD801 covers engine, transmission, ABS and airbag systems on VW models from 1990 to 2008, while a basic reader typically only handles engine codes on OBD II vehicles from 1996 onward.

What does the J1979 OBD II support mean when I plug the MD801 into my car?

It enables all nine standard test modes including live data graphing, freeze frame, oxygen sensor monitoring, on-board monitor results and component tests on compliant vehicles.

Which diagnostic connector does the MD801 use and what systems can it access through that port?

It connects through the standard 16-pin OBD II port and communicates over CAN where fitted, giving access to engine, transmission, ABS, airbag and TPMS modules on supported makes.
