Transmitter & RAC Programming

NOTE: Following procedure must be performed when replacing RAC module or either transmitter.
  1. Turn ignition switch to OFF position. Use a fused jumper wire and connect Data Link Connector (DLC) terminals 4 (Black wire) and 8 (Black/White wire). See Fig 1 . Door locks, fuel door and trunk lid release should activate in approximately 2 seconds.
  2. Press any button on one transmitter. Door locks, fuel door and trunk lid release should activate in approximately 2 seconds. First transmitter is now programmed. Repeat this step using other transmitter. If only one transmitter is being used, disconnect jumper wire from DLC. If module does not accept programming, see RAC MODULE CANNOT BE PROGRAMMED  under TROUBLE SHOOTING.
