1.1 How to Read the Diagrams
Each diagram has a Path No. range given to the system part. The Path No. range is
divided into 10 sections on the right side of the page. These path numbers give the
connections between related diagrams.
In the example below, the control air pipe that has the number 38 (page 3) goes to the
target path No. 51 (found on page 5).
Where two path numbers that are the same are shown, letter indications are used.
For example, on page 3, there are the numbers 38 and 38A. The number 38 is
Control Air and the number 38A is Air Spring Air.
