Individual measured values can be read out in Mode 1. Mode 1 is not recommended<br />

for VW dealerships as this data can be more accurately read under 01/function 04 or<br />

function 08.<br />

Mode 2 displays the operating conditions under which the malfunction was detected.<br />

With Mode 3 the DTC memory can be checked and with Mode 4 the DTC memory<br />

(diagnostic data) can be erased.<br />
