DESCRIPTION

  • The ECM turns on the cruise control SET indicator by sending indicator output demand signals to the combination meter assembly via CAN communication.
  • The cruise control SET indicator illuminates when the dynamic radar cruise control system is controlling vehicle speed.
  • The cruise control SET indicator circuit uses CAN communication. If the cruise control SET indicator is not functioning correctly, check for CAN communication DTCs before troubleshooting this circuit.
