WASTE GATE CONTROL

WASTE GATE CONTROL
M2132013000078
Turbo pressure used in the waste gate actuator is
controlled by duty control of the waste gate solenoid
valve. As a result, turbo pressure corresponding to
driving conditions can be obtained.

DIAGNOSIS SYSTEM
M2132009000893
Engine-ECU has been provided with the following
functions for easier system inspection.FREEZE-FRAME DATA
When the engine-ECU detects a problem and stores
the resulting diagnosis code, the engine condition at
that time is also memorized. The M.U.T.-III can then
be used to analyze this data in order to increase the
effectiveness of troubleshooting. The freeze-frame
