EC-48
< SYSTEM DESCRIPTION >[HR16DE]
OPERATION
• 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 t
he 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 AS CD 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 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 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 38 km/h (24 MPH) and less than 144 km/h (90 MPH)

Diagnosis DescriptionINFOID:0000000012542316
AUTO ACTIVE TEST
Description
In auto active test, the IPDM E/R sends a drive signal to the following systems to check their operation:
• Front wiper (LO, HI)
• Parking lamp
• Side marker lamp
• License plate lamp
• Tail lamp
• Front fog lamp
• Headlamp (LO, HI)
• A/C compressor (magnet clutch)
• Cooling fan
Operation Procedure
NOTE:
Never perform auto active test in the following conditions:
• Passenger door is open
• CONSULT is connected
1. Close the hood and lift the wiper arms from the windshield. (Prevent windshield damage due to wiper
operation)
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
2. Turn the ignition switch OFF.
3. Turn the ignition switch ON, and within 20 seconds, pr ess the driver door switch 10 times. Then turn the
ignition switch OFF.
4. Turn the ignition switch ON within 10 seconds. Af ter that the horn sounds once and the auto active test
starts.
5. After a series of the following operations is repeated 3 times, auto active test is completed.
NOTE:
• When auto active test has to be cancelled halfw ay through test, turn the ignition switch OFF.
• When auto active test is not activated, door swit ch may be the cause. Check door switch. Refer to DLK-98,
"ComponentFunctionCheck" (with Intelligent Key system) or DLK-232, "ComponentFunctionCheck"
(without Intelligent Key system).
Inspection in Auto Active Test
When auto active test is actuated, the following operation sequence is repeated 3 times.
Operation se-
quence Inspection location
Operation
1 Front wiper LO for 5 seconds → HI for 5 seconds

• Side marker lamp
• License plate lamp
• Tail lamp
• Front fog lamp (if equipped) 10 seconds
