Theory of Operation
The customer may notice that the signal range of the Remote Keyless Entry (RKE) system is reduced. The RKE key fob may need to be closer than 3 meters (10 feet) before the functions available on the key fob will operate. This condition may be due to the RKE antenna. The diagnostic flow chart is provide as a diagnostic aid for dealer technician.
| NOTE: | For all RKE tests, the key must be out of the ignition. |
