Using both transmitters, if available, perform the following procedure in order to diagnose all of the transmitter functions:

1. Resynchronize the transmitters to the receiver. Refer to Transmitter Synchronization .
2. Move the vehicle as far away from metal objects as possible.

The RKE system may not operate if there are metal objects between the transmitter and the vehicle.

3. Lower the windows.
4. Turn OFF the ignition.
5. Close the doors.
6. While standing at the rear bumper, aim the top of the transmitter at the vehicle.

Operate all of the functions on both transmitters, if available. Observe the results and make the necessary repairs, as follows:

•	If a single function on 1 transmitter is inoperative, replace that transmitter.

•	If all of the functions on 1 or both transmitters are inoperative, reprogram both transmitters and repeat Step 7. Refer to Transmitter Programming .

•	If you cannot reprogram 1 transmitter, replace the battery in that transmitter. Refer to Transmitter Battery Replacement .

•	If all of the functions on both transmitters operate, stand 1.5 meters (5 ft) from the vehicle and check the operation of both transmitters at several points around the vehicle.

•	If 1 transmitter does not operate from a point where the other transmitter functions correctly, replace the battery in the transmitter that does not operate. Refer to Transmitter Battery Replacement .

•	If both transmitters operate 1.5 meters from the vehicle, the system is operating properly. Do not attempt any repairs to the system.

•	For additional diagnostic information on the RKE module, refer to the RKE system check.
