High Speed Hybrid GMLAN Circuit Description

The high speed hybrid GMLAN serial data modules do not communicate directly with the scan tool. The SDGM communicates on all serial data busses and relays the high speed hybrid GMLAN serial data information to the scan tool. The high speed hybrid GMLAN serial data bus operates the same as the high speed GMLAN bus with the exception of the need of the SDGM for communication between the modules and a scan tool.
