HI
HAVE YOU TRIED DIFFERENT PROGRAMMER TO READ
SOME 9S12 SECURED NEED TO BYPASS BEFORE READ ALSO CHECK MASK ON MCU
HOW DOES ORIGINAL DUMP COMPARE TO CLONED MCU
IF ALL ELSE FAILS SWAP MCU OVER TO NEW CEM IF YOU CAN SOLDER
TRY CARPROG OR ORANGE 5 PROGRAMMER TO READ SOME DONT LIKE BEING READ IC NEED TO TAKE OFF BOARD ONTO ADAPTER THEN READ
ONCE THESE 2 MCU SWAPPED CAR SHOULD START NO PROBLEM
WHAT WAS FAULT WITH ORIGINAL CEM

HOPE THIS HELPS
