Programming the Control Module: Overview

The menu for P8.0 has 5 options. They are as follows:

1. "Determine Customer Service Measures"

This step is for special program modification updates that do not require an EPROM replacement (example M3.3.1). When activated, the program will automatically determine whether the vehicle it is connected to is eligible for a modification. If eligible, the modification will be displayed and can be activated by selecting the "Y" button. If the vehicle is not eligible, the program will display "No Programming Data Available for this SG Version".

Note:
Please disregard any Service Campaign numbers that may be displayed in the software. The control module may only be updated one (1) time.
