I have some issues with my 2009 F250 5.4L. Recently I got in the car and went to start it. It started fine but I was getting beeping noises from the dashboard. 5 beeps with 1 second between each beep for 3 times. I shut the car off and go to start it again and engine does not crank at all. I get the relay click every time i try to start it but engine doesn't want to crank. Then the beeps come back.
About a month ago I had a reputable shop here in town install a compustar remote starter. It hasn't given me any troubles at all but I'm thinking this might be the culprit behind the issue. I towed the car down to the place where they installed my remote starter and they got the car started. They said I had blown fuses and the remote starter is not behind the problem I'm having. So I picked the car up and it was all good for 4 days and last night I get in the car and same issue.
I scanned the car and came back with these codes
U2472 Ignition State Unexpected
B1868 Lamp Air Bag Warning Indicator Circuit Failure
U2023 Vehicle communication bus error
I tried resetting the codes and tried to start the car (it didn't) and another code popped up
B1555 for ignition run/start circuit failure.
Does anybody here have any idea whats going on? Or has anyone encountered this problem?
So i finally found out whats going on. My PATS fuse 5A keeps blowing. So I put a new one all good for 2 days and last night I went to get gas went to start the car and it blew the fuse again. I put some spares I had with me and the fuse blew as soon as I turned the ignition. Any suggestions on what to look for? Ignition? Pats transceiver? I'm lost here.
