SYSTEM DESCRIPTION

• The engine protection control at low engine oil pressure warns the driver of a decrease in engine oil pres-

sure by the oil pressure warning lamp a before the engine becomes damaged.

• When detecting a decrease in engine oil pressure at an engine speed less than 1,000 rpm, ECM transmits

an oil pressure warning lamp signal to the combination meter. The combination meter turns ON the oil pres-

sure warning lamp, according to the signal.

*: When detecting a normal engine oil pressure, ECM turns OFF the oil pressure warning lamp.

SWITCHES AND INDICATORS

SET SPEED RANGE

ASCD system can be set the following vehicle speed.

SWITCH OPERATION

SET OPERATION

Press ASCD MAIN switch. (The CRUISE indicator in combination meter illuminates.)

When vehicle speed reaches a desired speed between approximately 30 km/h (19 MPH) and 170 km/h (105

MPH), press COAST/SET switch. (Then SET indicator in combination meter illuminates.)

ACCELERATE OPERATION

If the ACCEL/RES 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. (M/T models)

• Selector lever is changed to N, P or R position (CVT models)

• Vehicle speed decreased to 13 km/h (8 MPH) lower than the set speed

(ACCELERATE/RESUME)

• Resumes the set speed.
• Increases speed incrementally during cruise control driving.

COAST/SET switch

• Sets desired cruise speed.
• Decreases speed incrementally during cruise control driving.

• 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 lamp.

• Engine coolant temperature is slightly higher than the normal operating temperature, CRUISE indicator may

blink slowly.

When the engine coolant temperature decreases to the normal operating temperature, CRUISE indicator will

stop blinking and the cruise operation will be able to work by pressing SET/

− switch or RES/+ switch.

• Malfunction for some self-diagnoses regarding ASCD control: SET indicator will blink quickly.

• Speed limiter MAIN switch is pressed.(Set speed is cleared.)

• ASCD MAIN switch is pressed.(Set speed is cleared.)

COAST OPERATION

When the COAST/SET switch is pressed during cruise control driving, decrease vehicle set speed until the

switch is released. And then ASCD will keep the new set speed.

RESUME OPERATION

When the ACCEL/RES switch is pressed after cancel operation other than pressing MAIN switch is performed,

vehicle speed will return to last set speed. To resume vehicle set speed, vehicle condition must meet following

conditions.

• Brake pedal is released

• Clutch pedal is released (M/T models)

• Selector lever is in other than P and N positions (CVT models)

• Vehicle speed is greater than 30 km/h (19 MPH) and less than 170 km/h (105 MPH)

ON BOARD DIAGNOSTIC (OBD) SYSTEM

ON BOARD DIAGNOSTIC (OBD) SYSTEM

Diagnosis Description

INFOID:0000000009022462

This system is an on board diagnostic system that records exhaust emission-related diagnostic information

and detects a sensors/actuator-related malfunction. A malfunction is indicated by the malfunction indicator

lamp (MIL) and stored in ECU memory as a DTC. The diagnostic information can be obtained with the diag-

nostic tool (GST: Generic Scan Tool).

GST (Generic Scan Tool)

INFOID:0000000009022463

When GST is connected with a data link connector equipped on the vehicle side, it will communicate with the

control unit equipped in the vehicle and then enable various kinds of diagnostic tests. Refer to 

EC-42, "Diag-

nosis Description"

.

NOTE:

Service $0A is not applied for regions where it is not mandated.
