Toyota Camry (XV70): Cruise Main Indicator Light Circuit
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 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.
CAUTION / NOTICE / HINT
NOTICE:
- Before replacing the ECM, refer to Registration.
