Checking Programming

NOTE:

The diagnostic trouble code (DTC) is stored if the central electronic module (CEM) registers that the software in the engine control module (ECM) is faulty or modified. Neither may software be remedied if the software has been changed by the customer, but this is not the reason for the repair work.
