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 status (presence or absence of a preceding vehicle, vehicle-to-vehicle distance, malfunction of system or related systems) of the dynamic radar cruise control system.
Before replacing the ECM, refer to Service Bulletin.
When the ECM is replaced, update the ECU security key.
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.
When the combination meter assembly is replaced, update the ECU security key.
Perform the Active Test according to the display on the GTS.
