TomsFocus Posted September 13, 2022 Share Posted September 13, 2022 You need the immobiliser to disarm. Is it keyed ignition or push button start? 1 Quote Link to comment Share on other sites More sharing options...

TomsFocus Posted September 14, 2022 Share Posted September 14, 2022 13 hours ago, ok99 said: key with a remote Ok. That means the key chip should be ok. This immobiliser active fault is fairly common on Mk4 Mondeos after a flat battery. You can try disconnecting the negative terminal of the car battery for 5 minutes, then reconnect, to reset the system. (But I have to warn you, it might also clear the remote locking from the key.) If that doesn't work, you'll need some diagnostic equipment to clear the immobiliser fault. In the UK we generally use Forscan but that may not be available for your area. A Ford dealer will have the correct equipment, but you would have to get the car towed to them, and then pay them for an hours labour or whatever their minimum charge is. 1 Quote Link to comment Share on other sites More sharing options...
ok99 Posted September 14, 2022 Author Share Posted September 14, 2022 36 minutes ago, TomsFocus said: בסדר. זה אומר ששבב המפתח צריך להיות בסדר. תקלת אימובילייזר פעילה זו נפוצה למדי ב-Mk4 Mondeos לאחר סוללה שטוחה. אתה יכול לנסות לנתק את המסוף השלילי של מצבר הרכב למשך 5 דקות, ואז לחבר מחדש, כדי לאפס את המערכת. (אבל אני חייב להזהיר אותך, זה עשוי גם לנקות את נעילת השלט מהמפתח.) אם זה לא עובד, תזדקק לציוד אבחון כלשהו כדי לנקות את תקלת האימובילייזר. בבריטניה אנו משתמשים בדרך כלל ב-Forscan, אך ייתכן שהוא לא זמין עבור האזור שלך. לסוחר פורד יהיה הציוד המתאים, אבל תצטרך לגרור את המכונית אליו, ואז לשלם להם עבור עבודה של שעת עבודה או מה שלא יהיה תשלום המינימום שלהם. hi i tried disconnecting the battery for 24h but it didn't help, i can't connect to obd, i tested with two elm327 plugs thnx Quote Link to comment Share on other sites More sharing options...
