Theory Of Operation

WARNING: This page is about a different variant/trim than selected.

After the controller is reset, the microprocessor checks the integrity of the program memory (ROM). A checksum is calculated by adding all used bytes in the program memory. The sum should be the same as a known constant stored in memory. The MIL will illuminate and the transmission will be placed into limp-in after 10 seconds of problem identification.
