DESCRIPTION When the
dynamic radar cruise control system is turned on using the cruise
control main switch, 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
NOTICE:
- Before replacing the ECM, refer to Registration.

- 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.
