SUBJECT:
Programming FLASH Control Modules

MODEL:
M44, M52, and M62

Situation:





The control module for the vehicles indicated in the table above no longer contains a removable EPROM but rather a soldered in EEPROM which can be reprogrammed/updated 13 times using the MODIC.

The information provided in this attachment is to serve as a guide/reference when using MODIC software version P7.1 or higher, whenever an engine control module needs to be updated or replaced.

NOTE:
It a replacement programmable control module needs to be ordered, do not order one by way of the parts fiche. A replacement control module should only be ordered based on the part number identification given by the MODIC. Only by installing the part number indicated by the MODIC will you be able to follow the procedure for programming a replacement control module as indicated in the procedure included in this bulletin.

For easy reference this procedure has been broken up into the following:

A. Explanation of the determination process.

1) Automatic determination (preferred)
2) Manual determination
3) Determination procedure considerations

B. Programming Troubleshooting Procedure

C. Programming Hints

D. Exchange control module - Determination and programming/updating of a currently installed or replacement control module using the MODIC.
