With HDS
- Press the lock or unlock button five or six times to reset the transmitter.
- If the locks work, the transmitter is OK.
- If any of the transmitter buttons do not work, replace the transmitter, then do the transmitter programming registration (see IMMOBILIZER KEY REGISTRATION ).
- If the locks don't work, go to step 2.
- Connect the HDS to the data link connector.
- Select the KEYLESS from the BODY ELECTRICAL menu, then enter the KEYLESS CHECK.
- Press lock, unlock, trunk, or panic button and check the response on the screen of the HDS.NOTE: The door lock actuators may or may not cycle when receiving input from the transmitter.
- If KEYLESS ENTRY TRANSMITTER CODE IS RECEIVED is indicated, the transmitter is OK. Go to KEYLESS OPERATION TROUBLESHOOTING .
- If DIFFERENT KEYLESS ENTRY TRANSMITTER CODE IS RECEIVED is indicated, the transmitter is not registered to the vehicle, if necessary, reprogram and register the transmitter (see IMMOBILIZER KEY REGISTRATION ).
- If KEYLESS ENTRY TRANSMITTER CODE IS NOT RECEIVED is indicated, go to step 5.
- Open the transmitter and check for water damage.
- If you find any water damage, replace the transmitter, then reprogram and register the transmitter (see IMMOBILIZER KEY REGISTRATION ).
- If there is no water damage, go to step 6.
- Replace the transmitter battery (A) with a new one, and press lock or unlock button and check the receive condition on the screen of the HDS.
- If KEYLESS ENTRY TRANSMITTER CODE IS RECEIVED is indicated, the transmitter is OK.
- If KEYLESS ENTRY TRANSMITTER CODE IS NOT RECEIVED is indicated, go to step 7.
- Use a different known-good keyless transmitter 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 the immobilizer system registration (see IMMOBILIZER KEY REGISTRATION ).
- If KEYLESS ENTRY TRANSMITTER CODE IS NOT RECEIVED is indicated, the immobilizer-keyless control unit is faulty, replace it and do the immobilizer system registration (see 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 programming is completed automatically.
