2.3.1 GMLAN Specific Publications. 
There are 
two types of GMLAN publications: General 
Specifications and Device Specifications. 
2.3.1.1 General Specification. 
The General 
Specifications establish the fundamental concepts 
needed by a GMLAN ECU (e.g., Communication 
Strategies, 
Bus 
Wiring, 
Physical 
Layer 
requirements, etc.) For a given ECU, it is possible 
that not everything in the General Specifications 
will apply. See Figure 1.
