When I start my 2014 XJL portfolio it says parking assistance not available consult dealer.
Anyone ever experience this? Is it a big deal?

 

mrivers51, odds are, one of your parking sensors is probably covered/failed and the system is not able to use the sensor. That or the module itself is not communicating and other modules are sensing this and putting up an error code. Atleast with the X-TYpes, you could put the car into say REVERSE and have a second person put their ear near the sensors. You could hear a high pitch squeal/chirp from the sensor when it was working. IF you didn't hear anything from a sensor, it was failed. If all the sensors were not sounding, then you knew the module was bad or not getting the reverse light signal. That may be an option you want to try. Atlesat the front, you can manually activate them and see if you can hear anything. Otherwise, you will need to connect up a higher end code reader and see what code(s) you are getting.

 

Yeah, I dont think any of the sensors are working and my back up camera won't come on either

 

mrivers51, well, then lets eliminate the easy stuff first and then go from there. i would say to start with starting the car and then pushing the parking aide button on the overhead console. Does it light up when the button is pushed? If no, then I would be checking fuse F3 in the rear junction box and then if that is good, swapping relay R5. If replacing relay R5 fixes things, then obtain a new relay and replace where you pulled the relay from or from the R5 (where ever the bad relay is). If yes, then we know that the parking aide module is atleast getting power supplied to it.

I am suspecting that you will find that the lights are going to work. At this point, we are down to most likely a MOD Bus issue. This would lead me back to an issue with either the gear shift selector or the tranny computer. I would start with doing the simple check of simply back up to a wall and seeing if your back up lights are lit. If those are lit, then we can rule out a mod bus data corruption issue and this would point back to a failed parking aide computer. The issue I am having is the mod bus feeds both the parking aide computer and the radio and the act of you putting the car in reverse tells both of these modules independently to perform a function (parking aide to start looking at the sensors, the radio to switch to the back up camera). So, with this in mind, I am suspecting that you are going to find that most likely you are going to find your gear selector to have a fault in it.

Hope this helps some. I am looking at the drawings and this is what it appears to be doing.

 

Do you know where I would find relay R5?
There is no fuse in the F3 space.

 

mrivers, Fuse F3 is in the well with the spare tire, not in the fuse box in the rear seat. So, that should clear up that. As for relay R5, that would appear to also be in the rear spare tire area. I am ust not finding any diagrams of the fuse boxes to be able to say relay R5 is the XXX relay down on this side.
