    • Connect the scan tool.
    • Key in ON position.
    • Enter the following diagnostic mode on the scan tool: FUNCTION TEST.
    • Monitor the TIC.
      • NOTE: The vehicle must be unlocked electronically through the remote transmitter or door lock control switch prior to using any diagnostic tools.
    • Verify the RKE transmitter signal is being received. Press the lock button on the RKE transmitter while observing the diagnostic tool.
    • Does the TIC show up on the diagnostic tool screen when the lock button is pressed?
