Interior scan function
About a week ago, the battery in my 56-plate Ford Focus hatchback started showing signs of failing – it’s the original Ford battery, so more than 10 years old. I used a radio code saver in the 12V socket and fitted a new battery.
The car now starts well and the radio is fine, however I’m getting a beep sounding every minute or so when the key is turned off or with the key not in at all. At the same time, a small orange warning light to the left of the mileage indicator window illuminates for a few seconds and a message comes up saying the interior scan is deactivated. This does not happen when the ignition is on or the engine is running.
I know there is a rocker switch to the left of the door handle on the inside of the driver’s door which can switch off the interior scan, but I was under the impression that once the car was opened again it reverted to a default setting of switching the scan back on. Malcolm Hargreaves
You are correct in saying that the interior scan should return to the default function of ‘On’ once the vehicle has been unlocked. There are no resetting procedures required after disconnecting the battery, so provided the correct battery has been fitted, the act of replacing the battery should not have caused any problems. I am
assuming you have tried using the dooroperated switch to reinstate the interior scan, but, if not, I would try this.
There is a slight possibility that the system has received a spike which has damaged the control unit at some point during the battery change. As you have the radio code, I would advise disconnecting the battery for a short period, which may help reset the alarm system. Other than re-entering the radio code after reconnecting the battery, the windows will have to be reset; this is easily done by turning the window switch to the ‘up’ position for a few seconds. If this does not rectify the problem, you may need to have the vehicle connected up to the Ford Worldwide Diagnostic System to locate the problem. It may just be a faulty door switch, but without a correct diagnosis you may end up replacing components at random and getting nowhere.
