3.3.1 Master module and slave module
!
When a VTEC unit is seen from
the front side (as on figure 1), the
first module is on the left side with lubri-
cant and air inlets – module position or-
der from left to right.
When a module doesn’t have one (or several)
of the control equipments (general air sole-
noid valve, air solenoid valve or pneumatic
pulse generator) it will depend for this func-
tion on the module mounted upstream,
which has the equipment(s). The upstream
module with the equipment is called ‘master
module’ and the other ‘slave module’.
Table 3 shows the different modules with
their main functions according to their
equipment.
