Question:

Hello Storey
I hope you can help me. I have had these problems with my Range Rover EAS. I used the EAS buddy and the fault message is: “RF signal incorrect”
Do you know what this means?
Thanks in advance
Henning

Answer:

The literal meaning of the fault, is “Right Front Height sensor Incorrect Value”. This is typically die to a faulty height sensor or a break in the wiring from the height sensor to the EAS computer. Some people believe that the EAS height sensors never fail and that it is the wiring that goes bad. Although I have heard of EAS height sensors failing in extreme high mileage vehicles. Over time, it is possible, that the EAS height sensor can develop a dead spot on the internal potentiometer sweep arm. This dead spot can be observed if you remove the height sensor and use an ohm meter while slowly moving the sensor. An old style analog needle ohm meter would be best, as you should be able to dramatically see the needle movement change inside a dead spot.
