Keyless Entry: Testing and Inspection

Perform the following check to diagnose all transmitter operations:

1. Move vehicle outside and as far away from metal objects as possible. Note: The RKE system may not operate if there are metal objects between the transmitter and the vehicle.

2. Turn ignition 'OFF', roll windows down, and close doors.

3. Stand at rear bumper, aim transmitter at the RKE antenna, and operate all functions on both transmitters.

- If a single function on one transmitter is inoperative, replace that transmitter.
- If a single function on both transmitters is operative, further diagnosis is needed.
- If all functions on one or both transmitters are inoperative, reprogram both transmitters and repeat diagnosis. If one transmitter will not program, replace the battery in that transmitter. If both transmitters will not program, open the trunk, hold the transmitter 2" from the receiver, and attempt to operate the system. If the system will not operate, further diagnosis is needed. If the system will operate holding the transmitter 2" from the receiver:

- Check the antenna for breaks and repair antenna using the procedure given later in this section.
- Check coax cable connections at the backlite and at the receiver. If the coax cable is disconnected from the backlite and both snaps are still in place on the glass, resnap the connector to the glass. If either of the snaps are not present on the backlite, use the procedure given later in this section to replace the snap.
- Replace the coax cable if above checks O.K.

4. If all functions on both transmitters operate, stand five feet from the vehicle at several points around the vehicle and check operation of both transmitters at each point.

- If one transmitter does not operate at some points where the other transmitter does operate, replace the battery of the transmitter that does not operate.
- If both transmitters do not operate at some points, check RKE coax cable connections at the rear window and at the RKE module.

Coaxial (Antenna) Cable:

- Check the coax cable ground at the roof inner by gently pulling the headliner back at the rear glass. Reattach the ground terminal if needed. See illustration.
- If both transmitters operate five feet from the vehicle, the system is operating properly and no repairs should be attempted.
