Fuel pump power supply fault CEM-B10C014
Hi everyone,
I'm really hoping someone can help me - I have a dead V70 (2010, D5) and I need to go on holiday in a week. It failed to start yesterday and it is showing the code CEM-B10C014 'Fuel pump power supply. General Electrical Failures. Circuit short to ground or open' The garage who have the car can't find the relevant locations of the fuse/relay and would also like to know how to access the fuel pump. I have had this problem before - the fuse diagrams I find online don't match the ones in my car. I tried other garages and even the main dealer but they can't fit me in for weeks. Any help gratefully received Thanks in advance. |

You will find the fuse in the CEM fuse box up under the glovebox. To access the pump you will need to drop the fuel tank, tho for testing purposes you should be able to slacken it enough and not need to remove it from the car.
Code description indicates broken wire. Obviously check the fuse, blown fuse indicates short to ground or shorted pump internally. check for power and ground at the pump ect but they should know what they’re doing.
