Saturn Odometer Incorrect
We replaced the bcm in this saturn about a month ago. Customer returned and said the odometer was incorrect. The display shows 81k but correct reading should be 141k. What will be required to correct the odometer issue?
Is the odometer even counting? Many times it will just lock at whatever the mileage is after the body control module was replaced because it says a discrepancy between the mileage stored in the Cluster and the body control module. In those cases it requires specialty software to make the mileage match between the instrument cluster and the body control module.
the bcm needs programming/setup assuming a new one was installed if a new bcm was installed and it was driven the bcm may be locked and would need to be replaced… I am guessing a used unit was installed a used unit would need eeprom work to correct it….
This is a somewhat common problem. I believe it’s a BCM problem but I’m not positive. I’ll try to double check my notes tomorrow.
Open up bcm and read mcu 908AS60 . That's holds milage and vin . Post it here I can modified for you
