Exchange Control Module

"Exchange Control Module"

This step is used to determine the basic control module part number that is to be used on the vehicle. This affects DME 3.1, 3.3.1, 3.3, 5.2 only. Under no circumstances should the parts microfiche be used in place of the determination step.

The programming procedure is divided into two steps:

Step 1 - Determining the basic control module.

The MoDiC reads the data (chassis number, part number of the basic control module, and part number of the programmed control module) necessary for programming from the defective control module and determines the part numbers of the possible basic control modules which may be installed in that vehicle.

Note:
Two part numbers will be displayed. The first number is for a new basic programmable control module. The second number is for a remanufactured basic programmable control module. Only order the remanufactured part number.

If this is not possible, the data may be read off the label of the defective control module and entered manually into the MoDiC.

Step 2 - Programming the basic control module.

The MoDiC programs the newly installed basic control module with the aid of the data derived by Step 1. The new control unit label can be printed out by the MoDiC station printer, or completed by hand.

The MoDiC programs the basic control module with the latest data. Because of this, the programmed basic control module may have a different part number.

Basic control modules may only be programmed one time. If a basic control module can no longer be programmed, the message "Basic control module defective. Install new control module" is displayed.

This procedure takes approximately three minutes. Extensive help information is available by pressing the "C" key on the MoDiC. This help information is only available when the "C" key is displayed.

Be advised that there may not be a Basic Programmable Control Module available for all DME Control Module versions. In this case, a new preprogrammed control module must be installed.
