Poor Operating Range Performance
2005 Ford Econoline E150, Van Cargo, 5.4 LSECTION Poor Operating Range Performance
If extremely poor operating range is experienced:
- Do not change transmitter batteries. Range is not affected as the battery ages.
- Do not replace or reprogram transmitters. Range performance is determined primarily by the receiver control module.
- If range performance exceeds about 30 feet (10m), do not replace the fob or module. This is within design limits.
- If range is consistently less than 10 feet (3m) from the center of the vehicle, the system can be considered "compromised" provided the following factors are first ruled out:
- Verify external antenna is connected (if equipped - e.g. Focus and Freestar).
- Ensure issue exists all the time versus just in specific locations. Such as by local grocery store, radio stations, TV transmitting towers or by buildings with power generators.
- Ensure no other aftermarket or dealer installed systems are on vehicle when troubleshooting. (Examples: other RKE, remote start, perimeter alarm systems, etc.)
- Ensure issue is consistent in nature and not just from one approaching angle from/to the vehicle.
