Flashing O/D Light

[RPurdy]

What does it mean? I couldn't find anything helpful on google.

It could be setting a converter slip code. Need to get it scanned for codes. Shifting any different?

[RPurdy]

No. She shifting fine. I actually am not sure if it was there while I was driving. I noticed it when I put it in park and was just sitting there listening to the radio.

Check your blinker and tail light bulbs, my guess is one of them is out.

Never seen that cause an O/D light to flash. Stranger things have happened though.

Not doubting your advice but who the hell designed that and said "Oh your blinkers and brake lights are out, Lets have the OD light flash to let them know!"

[Nashotah7]

Believe or not, Ford did. The blinker and tail lights are all tied together with your OD light. I thought the same thing when I first was told this, but I always know when I have a bulb out......lol

I'd have to see that first hand cause I don't buy it. I could always tell if a bulb was out because my turn signal would flash faster.

Well we will have to wait and see what he comes back with, but it is a fact that they are all tied together. I have owned my truck since new and everytime I see it blinking the first thing I do is check my bulbs, and everytime I find one out. Just telling you what I have experienced and what I have been told.

Actually, this might be brilliant. I have the Centurion running boards. And its a dually. And I have cab lights, would it be linked to any of those too? I have a million lights on my truck haha
