Test 09 Status Mileage In Km

WARNING: This page is about a different car, the 2002 BMW M Roadster, 2002 BMW M Coupe, 2001 BMW M Roadster, and 2001 BMW M Coupe. However, it is still accessible from the selected car via links, so may be relevant.

Information and matching of any difference occurring between the km reading in the encoding connector and the redundant value soldered in the EEPROM.

e.g. display GWSZ---signifies identical readings from EEPROM "E" and EEPROM "I"

(E = external EEPROM in encoding connector)

(I = internal EEPROM in instrument cluster) e.g. display on GWSZ 012654 I

There is a difference in the km readings stored in memory. The value displayed (e.g. 012654 I) is always the lower reading.

The supplement "I" indicates that this is in the internal, i.e. the soldered EEPROM. An "E" signifies the external EEPROM (encoding connector).

In addition, if counter readings differ, the manipulation point lights up.

After replacement of cluster or encoding connector, the higher km reading in the EEPROM can be matched to the lower reading by holding down the reset button when selecting the test function 09 for > 4 secs. At this point, the SIA data is also transmitted. After successful matching, the manipulation point disappears.

CAUTION: Replacement part must always have a smaller km reading otherwise the vehicle-specific km reading is overwritten.
