Over voltage would likely be related to the alternator voltage regulator. Electrics can cause intermittent problems - You can easily measure the voltage with a multimeter 13.5 - 14.5 volts would be pretty typical if the voltage is much higher than this then the regulator needs attention.

Check your muffler for blockage. Does the engine heat up? A blocked muffler will allow an engine to run but acceleration is almost impossible.

SOURCE: Auto door locking on Ford Mondeo

It sounds like it has been deactivated so we are going to reactivate the auto lock.

The numbers I will be saying will have to do with getting this to work so:
you will need to put the key in to the ignition switch.

1= is back to listen to the radio
2= is to get key out
3= is just before you start
4= is for starting your car

When we do this 1 and 4 will not be used
Do this and we will hope that it works like it should:

1: Turn the ignition with you key up to on( don't start)

2: Press the power door lock control 3 times

3: now turn the key back once (to off position)

4: Press the power door unlock control 3 times

5: ok turn the ignition back up 1 time. (The horn should chirp)

6: Then press the unlock control, then press the lock control, again (horn will chirp 1's) If auto lock
was activated.

7: Turn the ignition back 1's, Then the horn should chirp once to confirm the procedure was completed.

SOURCE: ford mondeo 2001 has misfire and wont tick over

Any engine will have trouble ticking over if only 3 of the 4 cylinders are working. Check the spark plug for a consistent spark on all cylinders. Check the connections to the fuel injectors on the cylinder head, and check the compression in all cylinders (take spark plugs out and use a compression tester whilst turning the engine over on the key). Low compression in one cylinder may mean head gasket failure, valves out of adjustment (staying open) or bigtime piston or piston-rings failure.

Service engine soon light is on, and the codes its giving are f110p and 1891p

P1891 20500 System Voltage High Input
This fault sets when the alternator is failing. But instead of failing where the voltage is too low it is too high. This is just as bad if not worse than too low. Your 7 series is full of computers and when they see this high voltage they start to go into failsafe to protect themselves. The overvoltage could even cause modules(computers) to fail.
Some modules very effected by this is the DSC control unit, EGS Transmission control unit. This type of problem will come and go due to the alternator is intermittently overcharging.
Now there MIGHT be other things going on but it ALWAYS is a bad alternator with the overvoltage fault in my experience. This alternator is a bit hard to do so I do recommend having the dealer replace it. Make sure you tell them about the overvoltage and even this post as most tech's easily overlook this fault and go chasing the "failsafe" problem and never stop to look at the big picture --system voltage.
I hope this information is helpful. Please accept and let me know if I can help you further.Thank you.

Very possible. If the alternator is overcharging, the computer and other components can be affected, even damaged.

1 Answer


A vehicle alternator control device in which, when a signal detection portion detects a determined input signal, an operating mode of an overvoltage warning portion is switched to a detection operating mode by an overvoltage warning operating mode switching portion. In the detection operating mode, the overvoltage warning portion is activated when a voltage below a determined voltage has continued for a time that is less than a determined time. Accordingly, checks related to the operation of the overvoltage warning portion can be completed in a short time at a plant or the like.
