Presentation in hexadecimal numbers (refer to illustration and table which follows test functions).
Test 07 Engine speed
Display of prevailing engine speed in rpm.
Test 08 Roadspeed
Display of current vehicle road speed always in km/h (not in mph).
Test 09 Status mileage in km
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.
Test 10 Statusbits (input modes)
Display binary in GWSZ (mileometer)
0 = input low,
1 = input high
Test 11 Statusbit (output modes)
Display binary in GWSZ (mileometer)
0 = Output inactive,
1 = Output active
Test 12 free
