Hi, 

Need help for odometer correction. Bus have tachograf Kienzle and it odemeter show 325079km, but cluster have inside eep 93c66( first two lines show  values B3D2) with 625050 km.
How to adjust mileage when dash show different km than tacho? It looks like they are not connected to each other.
Will be ok if I adjust km in cluster or need correct ezs(Temic box) to get km the same as tacho?
The tachograph has a red safety stamp.

When disconnect tacho and then switch it on with connected dash nothing change, dashboard always show 625050km, tried many variants, dash all time show 625050.
Here no ----- just indicated km

Here will be dump from dash

Please need the same km as show tacho

i think you must correct ezs also, MC9S12DT256- 0L01Y

ok, need correct dash and the same km put in ezs? About ezs , here is standard flip key, not like with infrared, than where is located this ezs module?

[al70]

yes, you must do both, read ezs also and post file

I can't find ezs, here is standard ignition barrel cylinder something like in the picture, not  ignition black box and under it come big black fuse box.

AHH, I'm not sure then jancss, have you already changed mileage in cluster ?

[Jancss]

Nop , haven't.... I tried just without writing in eeprom, but I can't get the exact km, either the reading is too small or too much...
