Understanding the file label
The MOD label identifies this file as a modified variant. The related catalog entry 89663-07071 provides the base identifier, but it does not describe the changes in the modified file.
The E2 suffix is a variant label. On its own, it does not establish a specific function or change in vehicle operation. The full identifier should therefore be checked against the vehicle’s controller and calibration records rather than matched by the 89663 prefix alone.
