Ok, I'm a 'newbie', and I have a weird kind of issue. Remote locking with the fob does not lock the fuel cover, but if I unlock the car with the fob, and then leave it, when it auto locks, it locks the fuel cover. Can anybody help with what is going on? I've checked the lock motor itself, and it tests out fine, so I figure the fault is somewhere in the electric system, as putting a multi-meter on the wire gives a pulse on unlock from the fob, but no pulse on lock.

 

The fuel door don't work with your fob, it not lock until the wheel rolling several feet. read your manual.
