service AUDI A4 1997 B5 / 1.G AFC Engine On Board Diagnostic Multiport Fuel Injection Workshop Manual

01-3
Modes under address word 33:
Mode 1: Transfer diagnosis data Switch ignition on or let engine idle
Mode 2: Transfer operating conditions Switch ignition on or let engine idle
Mode 3: Check DTC memory Switch ignition on or let engine idle
Mode 4: Erase diagnosis information Switch ignition on or let engine idle
Mode 5: Output of HO2S signals Switch ignition on or let engine idle
Mode 6: Read test results (starting with control module 8D0 906 266 A) Switch ignition on or let engine idle
Mode 7: Read test results (starting with control module 8D0 906 266 A) Switch ignition on or let engine idle

Under address word 33, Mode 1 to Mode 5 can be selected starting from control module 8D0 906 266 and Mode 1 to
Mode 7 starting from control module 8D0 906 266 A.
Individual measuring values can be read under Mode 1. This is not recommended for Audi service department since this
information is available more easily under address word 01, function 04 and/or function 08.
Mode 2 shows the operating conditions under which a malfunction was recognized.
Mode 3 is used to check the DTC memory and Mode 4 is used to erase the DTC memory. In the Audi service department,
only address word 01, function 05 should be used to erase, since with Mode 4 the DTC memory is erased immediately
even if it was not checked first.
Static variables of HO2S probes, required by legal regulations, are displayed under Mode 5. Since these variables have
no direct relationship to HO2S diagnosis, Mode 5 is not needed by the Audi service department.
