Hi guy, I acquired a 2014 Jaguar xjl from my uncle. He was rear ended the car still starts but it does not see the key unless i put it by the sensor by the wheel on the left side then it starts up. Also after the collision the virtual dash was working fine but now it doesn't display it will show park or headlight or smart key not found but the speedometer doesnt show. the radio isn't working either is there a fuse or certain module i should check out? Only thing ive done was disconnect the rear bumper harness and put a new battery in the car and remote. Any help is greatly appreciated

 

Why wasn't the damage covered by insurance?

 

Fx3kid, let me do some looking at the diagrams that I have. Sounds like you have a single fuse that is blown that is affecting both the instrument cluster and the key.

 

Fx3Kid, look in the central junction box at fuse F61. It is a 10 amp fuse. Then you will want to check fuse F69 in the same junction box. This will be a 15 amp fuse.

The other place you are going to want to look is in the trunk area. There should be a fuse box near the battery that is going to have some larger fuses associated with that fuse box (40+ amp fuses). If you look, you should see 2 fuses labeled BCM_3 and BCM_4. Both of these are 40 amp fuses. I bet you will find that one of these is blown. It may be even possible that the associated wires (BCM_3 has a blue wire with a red stripe running from it and BCM_4 has a green wire with a red stripe running from it) were damaged in the accident and shorted to the chassis of the car, causing what you are seeing.

If this does not fix your problem, let me know and we can take things from there.

 

They payed him off and he has given the vehicle to me

 

Thank you for your quick response i checked both the fuses in central junction box f61 and f69 as well and they were good ,also checked those 40 amp fuses and wiring and they seem fine i even bypas the fuse with no luck same symptoms. Also the radio does not power on or have any light if that helps the rear bumper harness was damaged so it is unplugged the key doesnt lock or unlock from the fob i cant even see the little jaguar logo on the cluster its simply blank but will show ignition on, and headlight logo when switched on.please let me know what you recommend thanks in advanced.

 

Fx3kid, odds are, you have power disconnected from the virtual dash because of the harness that you unplugged. Those 40 amp fuses feed power to the dash. You have the harness unplugged, it doesn't get al the power it needs, hence the limited indications that you get. Sounds like you are going to need to fix the rear wiring harness before you are going to get the dash back.
