  2. Connect the HDS to the data link connector.

    NOTE: The door lock actuators may or may not cycle when receiving input from the transmitter.
    • If KEYLESS ENTRY TRANSMITTER CODE RECEIVED is indicated, the transmitter is OK.

    • If KEYLESS ENTRY TRANSMITTER CODE IS NOT RECEIVED is indicated, go to step 5.

  7. Use a different known-good keyless transmitter assembly, and repeat steps  3 and  4.
    NOTE: The keyless transmitter does not need to be programmed to the vehicle for this test.
    • If DIFFERENT KEYLESS ENTRY TRANSMITTER CODE WAS RECEIVED is indicated, replace the keyless transmitter, and do the immobilizer system registration (see IMMOBILIZER KEY REGISTRATION ).
    • If KEYLESS ENTRY TRANSMITTER CODE WAS NOT RECEIVED is indicated, the immobilizer-keyless control unit is faulty, replace it, and do the immobilizer system registration (see IMMOBILIZER KEY REGISTRATION ).
    NOTE: The keyless transmitter is combined with the immobilizer transponder, so when the transponder is registered by the HDS, the keyless transmitter is also registered automatically.
