1.
caution |
Conduct the driving test in a location where driving
at full acceleration can be done with safety. Two person should be in the vehicle when the test
is conducted; the person in the passenger seat should read the indications shown by the M.U.T.-III.
|
Set the vehicle to the pre-inspection condition.
|
|
2.Turn the ignition switch to the "LOCK" (OFF) position and then connect the M.U.T.-III
to the diagnosis connector (Refer to GROUP 00 - Precautions Before Service, M.U.T.-III ).
|
|
3.Use the data list function named "Item No. 6" boost pressure sensor of the M.U.T.-III
to check the supercharging pressure when the engine speed increases to approximately 3,000 r/min
or more by driving at full acceleration in 2nd. Standard value:
<Vehicles without intercooler> 194 - 234 kPa <Vehicles with intercooler> 181 - 221 kPa
|
|
4.If the supercharging pressure deviates from the standard value, check the following
items for possible cause.
- Malfunction of the waste gate actuator
- Malfunction of the manifold absolute pressure sensor
- Leakage of supercharging pressure
- Malfunction of the turbocharger
|
|
5.When the indicated supercharging is more than standard value, supercharging control
may be faulty, therefore check the followings.
- Disconnection or cracks of the waste gate actuator rubber hose
- Malfunction of the waste gate actuator
- Malfunction of the waste gate valve
- Malfunction of the manifold absolute pressure sensor

4.If the supercharging pressure deviates from the standard value, check the following
items for possible cause.
- Malfunction of the variable geometry actuator
- Malfunction of the variable geometry control solenoid valve
- Malfunction of the variable nozzle

- Leakage of supercharging pressure
- Malfunction of the turbocharger
- Inadequate vacuum pressure to the variable geometry control solenoid valve
