Keyless Entry Transmitter: Testing and Inspection
TRANSMITTER ID CODE REGISTRATION
CAUTION:
- Always program three ID codes because the programming mode terminates if three ID codes are programmed. At this time, the same transmitter (programmed transmitter) can be programmed two or three times.
NOTE:
- Always program three ID codes because all the programmed ID codes prior to activation are cleared when the programming mode is activated.
- A maximum of three ID codes can be programmed.
- When programming the ID code into a keyless control module, verify that other transmitters are not being operated in the vicinity.
- After ID code programming, remove the key from the steering lock and verify that all doors lock/unlock normally using the transmitter.
