DESCRIPTION
When the cruise control main switch is on, the CRUISE main indicator light and READY indicator light come on. This indicates the control condition (presence or absence of a vehicle in front, vehicle-to-vehicle distance, and set vehicle speed) and fail-safe state through the multiplex communication system. The master warning light and CRUISE main indicator light come on and vehicle-to-vehicle distance information is displayed on the combination meter as the alarm buzzer sounds.
HINT: If the vehicle in front in the same lane significantly decreases vehicle speed or another vehicle cuts in front of your vehicle, adequate deceleration cannot be applied and the vehicle-to-vehicle distance will shorten. At this time, the system sounds the buzzer and the multi-information display blinks to warn the driver.
INSPECTION PROCEDURE
1 PERFORM ACTIVE TEST BY INTELLIGENT TESTER
METER:
OK: Indicator light blinks/goes off.
2 READ VALUE OF INTELLIGENT TESTER
ECM (Cruise control):
OK: When the cruise control main switch is operated, the display changes as shown above.
HINT: "1" is OK, but "2" is NG → DTC output or ECM failure
