Hi there, I have been having a problem lately with the warning lights going crazy in my dash. On start up it will throw the tire pressure, brake,traction and sometimes the driver door ajar warning and then go away as I continue driving. It does not happen all the time, but seems to be more often lately. I noticed today when it happened, the turn signals did not work either. When the warning lights went out, the operation of the turn signals returned. I know it is not the tpms system because I just replaced all four sensors and reprogrammed the computer. When the sensors were bad, the warning would not clear and was not accompanied by any other warnings. I am a little confused as to what would set all of these warnings off at once and then go back to normal operation. I have searched on here, but found nothing close to my problem. Could this be a wiring harness issue causing this? I checked my tire pressures and all were correct.
I found something close that said to lube the door latch with spray and replace the door harness due to the wires breaking from the repeated opening and closing of the door.
Thanks in advance for any input you may have.

 

This sounds similar to what I'm having with my 2011 f150 3.7. Except mine will not start when I shut it off and this is happening.


First indication of problems was a 'service advance trac' warning light, then the system deteriorated from there. Ford has not found the problem as of this date.

 

Now it is pretty much all the time emergency brake light, tpms, traction control and no door ajar when the door is opened or turn signals in the dash. Outside turn signals work though. Looks like I gotta dig into this one. Going to read the codes first and see where that leads.

 

a bit of difference on mine - it shows the turn signal flashers inside and signals outside, but only if the stalk is HELD to LH or RH turn. Else it will give a lane change (three and off) signal only - will not lock into the signal left/right mode.


Service manager at my local dealer is having the mechanics confer with ford engineering. Still no solution here, but they are beginning to suspect a wiring harness in the transmission.

 

Update on this issue. I was driving down the highway outside Chattanooga today and hit a small bump in the road and I heard a ding and all the warnings went away and everything was back to normal. I think my problem is a loose connection somewhere up in the cluster. At least that is where I am going to start.

 

Problem fixed.

 

Glad you found it.
And thanks for reporting back.
Hopefully it will help someone else. p
