  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 IS RECEIVED is indicated, replace the keyless transmitter and do IMMOBILIZER KEY REGISTRATION .
    • If KEYLESS ENTRY TRANSMITTER CODE IS NOT RECEIVED is indicated, the immobilizer-keyless control unit is faulty, replace it and do IMMOBILIZER KEY REGISTRATION .
    NOTE: As 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.
