The Chassis Number Ranges listed are only for informational purposes and are not to be considered as the only deciding factor.

Correction:
Reprogram the DME with CD 21.0 or higher.

Procedure:

1. Check the DME identification screen on the DIS/MoDic.

2. If the basic control unit and the programmed control unit number match the following:

Basic Control Unit Programmed Control Unit
7 831 762 7 831 872

the DME has already been reprogrammed and no further programming is required. If these numbers are not listed, reprogram the DME.
