Service Point
• Engine Oil Pressure Control Check
 Oil pressure switching valve is forcibly operated by using the
intelligent tester
• Tester Menu: Powertrain > Engine and ECT > Utility >
Engine Oil Pressure Control Check
HINT:
• This check requires the following vehicle conditions.
- Engine is idling and warm it up.
- Vehicle is stopped.
- Acceleration pedal is not depressed.
- Shift position is in Neutral.
• During this check, the engine speed will increase
(Approx. 2,000 rpm) and the oil pressure switching
valve will switch automatically.
- Oil pressure switching valve cannot be switched
manually.
NOTE:
20 Perform this check when DTC P0524 is output.

Vehicle Conditions
Engine Control System
System Control Table [2/2]
System
Outline
Based on the signals received from the various sensors, the ECM determines
throttle position in accordance with engine condition.
Intake Throttle Control
Fully closes the diesel throttle control valve in order to reduce the vibration
when the engine is stopped.
Cooling Fan Control
Cooling fan operation is controlled by signals from the ECM based on the
coolant temperature, air conditioning condition*1.
Air Conditioning Cut-off
Control*1
By turning the air conditioning compressor on or off in accordance with the
engine condition, drivability is maintained.
Starter Control
(Cranking Hold Function)*2
Once the engine switch is pushed, this control continues to operate the starter
until the engine is started.
Engine Immobiliser
Prohibits fuel injection if an attempt is made to start the engine with an invalid
ignition key.
Oil Maintenance
Management System
When the ECM determines that the engine oil has deteriorated, when the
engine oil level sensor detects that the engine oil level has increased, or when
the running distance exceeds a predetermined value, the engine oil change
reminder indicator light turns on to inform the driver of it.
Brake Override System
When the brake pedal is depressed while driving with the accelerator pedal
depressing, this system may restrain the engine output and support brake
performance
