SYSTEM
OIL CONTROL SYSTEM : System Description
INFOID:0000000010471231
DESCRIPTION
ECM calculates oil degradation based on engine speed and vehicle speed, and displays engine oil change
timing on combination meter.
When the mileage before engine oil change comes to approximately 1500 km or less, pre-alert message is
displayed to inform the driver that the maintenance timing is close as shown in the following table.
At oil change, the mileage must be reset using combination meter function. For how to reset, refer to
ECK-
147, "Description"
.
NOTE:
• Alerted mileage might be different from actual mileage.
• The level of oil deterioration may be increased depending on the status of vehicle use (e.g. frequent short-
distance driving and engine start).
ECM calculates two types of oil deterioration
• Oxidation
• Dilution
Calculating oxidation of engine oil
Based on engine speed, ECM calculates the degree of oxidation of oxidation by adding correction value calcu-
lated from engine oil temperature and so on.
Calculating dilution of engine oil
ECM calculates the degree of dilution, based on air temperature, injection quantity at post-injection, the num-
ber of regeneration and so on.
AUTOMATIC SPEED CONTROL DEVICE (ASCD)
AUTOMATIC SPEED CONTROL DEVICE (ASCD) : System Description
INFOID:0000000010289655
BASIC ASCD SYSTEM
Automatic Speed Control Device (ASCD) allows a driver to keep vehicle at predetermined constant speed
without depressing accelerator pedal. Driver can set vehicle speed in advance between approximately 40 km/
h (25 MPH) and 180 km/h (119 MPH).
ECM controls fuel injector to regulate engine speed.
Operation status of ASCD is indicated on the information display in the combination meter. If any malfunction
occurs in ASCD system, it automatically deactivates control.
NOTE:
Always drive vehicle in a safe manner according to traffic conditions and obey all traffic laws.
SET OPERATION
Press ASCD MAIN switch. (CRUISE indicated on the information display)
When vehicle speed reaches a desired speed between approximately 40 km/h (25 MPH) and 180 km/h (119
MPH), press SET/COAST switch. (SET indicated on the information display)
ACCELERATE OPERATION
If the RESUME/ACCELERATE switch is pressed during cruise control driving, increase the vehicle speed until
the switch is released or vehicle speed reaches maximum speed controlled by the system.
And then ASCD will keep the new set speed.
CANCEL OPERATION
When any of following conditions exist, cruise operation will be canceled.
• CANCEL switch is pressed
• More than 2 switches at ASCD steering switch are pressed at the same time (Set speed will be cleared)
• Brake pedal is depressed
• Clutch pedal is depressed or gear position is changed to neutral position.
• Vehicle speed decreased under 15% of the set speed from the set speed.
• TCS system is operated.
When the ECM detects any of the following conditions, the ECM will cancel the cruise operation and inform
the driver by blinking indicator.
• Engine coolant temperature is slightly higher than the normal operating temperature, CRUISE indicator may
blink slowly.
