Manually Entering a Variant Code

The process of manually entering a variant code should only be utilized when it is not possible to communicate with the Engine Control Module (DME) via the DISplus or GT1. The variant code to be entered can be taken from the label of the problem control module and checked against the listing of variant codes provided in SI B13 02 90 (3009)  prior to entering the code into the new module.
