DYNAMIC RADAR CRUISE CONTROL SYSTEM Cruise Main Indicator Light Circuit

DESCRIPTION

When the dynamic radar cruise control system is turned on using the cruise control main switch (ON-OFF), the cruise control indicator (vehicle-to-vehicle distance control mode) illuminates. The ECM uses this and other indicators to indicate the control condition (presence or absence of a preceding vehicle, vehicle-to-vehicle distance, and set vehicle speed) and fail-safe state via CAN communication.

CAUTION / NOTICE / HINT

Note


  • When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.

  • Before replacing the ECM, refer to Service Bulletin.
