Optical Testing & Programming System (OPPS )

WARNING: This page is about a different car, the 2003 BMW 760Li, 2003 BMW 745i, and 2003 BMW 745Li. However, it is still accessible from the selected car via links, so may be relevant.

Optical Testing and Programming System (OPPS) is a device that may be used instead of the diagnostic head as a vehicle interface for either DISplus or GT-1. When used, it replaces the diagnostic head. OPPS was developed to reduce the amount of time required to program E65/E66 MOST control modules by 30-60 percent and to diagnose fiber optic communication systems MOST and Byteflight. OPPS can be connected into the MOST bus and the OBD-II connector simultaneously.

OPPS comes with 2 OBD-II cables. A short version (663 111) is used for CIP programming through the OBD-II connector, and MOST bus as well as diagnosis of all E65/E66 modules. A long version (663 112) is used for optical module and bus testing of modules located a distance from vehicle OBD-II connector such as in vehicle trunk. Long OBD-II cable (663 112) only transmits at a baud rate of 10400 compared to the high speed 115K baud for 663 111.
