Thread: No power to 12v aux socket & phone integration

Steve, pretty much yes and as Tombie says, continuity test will show this. As an example, this video shows you multiple ways to test a fuse including the continuity test. Just skip the test light stuff if you don't have one.

Are any of the accessory outlets working? If so then the relay (R203) is OK. If none are working then either the relay has failed or link 17E (engine bay - 50A) may have blown.

However the cigarette lighter outlet, which IIRC is the driver's side outlet, uses fuse 55P and relay R132 fed by FL 18E (50A).

Just removed fuse 55P ... this is the unserviceable fuse !! All I have to do now is get a new one. There doesn't seem to be a spare 15 amp fuse in the panel.

Your advice and help has been much appreciated as well as other members that have contributed. Just hoping that it fixes all the issues. We'll see!

The question remains, why did the fuse blow? Don't be tempted to put in a larger amperage fuse.
Di you ever get power back on to the reversing camera? Is an aftermarket camera or LR original?

I've just finished replacing the 55P fuse with the same value fuse (15 amps) and I have:-

1. power to the 12v aux socket (cigarette socket next to driver's seat)
2. recognition of the phone system.
3. power to the aftermarket video screen BUT "NO SIGNAL" shown on the screen thus no picture from the rear view camera. It's a cable connection to the camera. Actually to tell you the truth there has always been power to the video screen just not the signal.

Not sure what next.

Looks as though the problem with loss of signal to the video screen has been rectified.

I checked all fuses in the rear compartment ... all appeared ok. Then checked the cable to the rear view camera which seemed intact. Left everything for a while. Started the car, switched on the video screen to find all is working perfectly.

What caused the problems in the first place. I don't know. However I've discovered the Hema navigator I use (which powers from the faulty 12v socket) has a faulty charger.

Good candidate for the cause. How did you determine that it's faulty?

Noticed a crack in the charger housing where the cable enters .. seemed loose. Checked it out in another vehicle .. didn't work. Used another charger from a similar device and it worked. Checked that charger out in the disco & no problems.
