Hi everybody. I wrote SBL for CEMB to read the full contents of the flash. While in test mode, CAN packets are transmitted in uncontrolled mode with 8 bytes of data. 512 KB is transmitted in 1.3 minutes. The period between CAN packets is 1.192 milliseconds. I receive all data packets on the ...

Yes there is the problemTo the CEM with a Xprog
ECM i do nothing

the synchro is problaby not matching in the ecm. Take a backup and check it. Did you correct the checksums ass wel

Did you transfer anything on the new CEM beside a transoponder key, are CEM matching HW and so on . Did u use a fresh ECM write or Maybe the CEM still has a previous Vin in it . but u can copy syncronisation blok and write it in de ECM .

Question about the 5v+ over 1k resistor, when done with writing complete, does de resister stays of remove it when done ?
