Toyota Tacoma 2015-2018 Service Manual: Cruise Main Indicator Light Circuit
DESCRIPTION
When the dynamic radar cruise control system is turned on using the cruise control main switch (ON-OFF button), 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.
