Nissan Versa (N17): Automatic speed control device (ASCD)

Automatic speed control device (ascd) : switch name and function

SWITCHES AND INDICATORS

1. CRUISE indicator 2. CANCEL switch 3. ACCEL/RES switch 4. COAST/SET switch 5. ASCD MAIN switch A. On the combination meter B. On the steering wheel

SET SPEED RANGE

ASCD system can be set the following vehicle speed.

Minimum speed (Approx.)	Maximum speed (Approx.)
38 km/h (24 MPH)	144 km/h (90 MPH)

SWITCH OPERATION

Item	Function
CANCEL switch	Cancels the cruise control driving.
ACCEL/RES switch	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.
ASCD MAIN switch	Master switch to activate the ASCD system.

SET OPERATION

Press MAIN switch. (The CRUISE indicator in combination meter illuminates.) When vehicle speed reaches a desired speed between approximately 38 km/h (24 MPH) and 144 km/h (90 MPH), press COAST/SET switch.

ACCELERATE OPERATION

If the ACCEL/RES switch is pressed during the 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, the cruise operation is canceled.

• CANCEL switch is pressed
• ASCD MAIN switch is pressed (Set speed is cleared)
• More than 2 switches at ASCD steering switch are pressed at the same time (Set speed is cleared)
• Brake pedal is depressed
• Selector lever is changed to N, P or R position
• Vehicle speed decreased to 13 km/h (8 MPH) lower than the set speed
• TCS system is operated

• When the ECM detects any of the following conditions, the ECM cancels the cruise operation and informs the driver by blinking CRUISE indicator lamp.

• Engine coolant temperature is slightly higher than the normal operating temperature, CRUISE indicator lamp is blinked slowly.

  NOTE: Engine coolant temperature decreases to the normal operating temperature, CRUISE indicator lamp stop blinking and the cruise operation is able to work.

• Malfunction for some selfdiagnoses regarding ASCD control: CRUISE indicator will blink quickly.

• When ASCD MAIN switch is turned to OFF during the cruise control driving, all of ASCD operations is canceled and vehicle speed memory is erased.

COAST OPERATION

When the COAST/SET switch is pressed during the 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 the cancel operation other than pressing ASCD MAIN switch is performed, vehicle speed is return to last set speed. To resume vehicle set speed, vehicle condition must meet following conditions.

• Brake pedal is released
• Selector lever is in other than P and N positions
• Vehicle speed is greater than 38 km/h (24 MPH) and less than 144 km/h (90 MPH)

On board diagnostic (obd) system

Diagnosis Description

This system is an on board diagnostic system that records exhaust emissionrelated diagnostic information and detects a sensors/actuatorrelated 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 diagnostic tool (GST: Generic Scan Tool).

Gst (generic scan tool)

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.

NOTE:

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