I finally got my 4x4 to work. I got the 4x4 and 4Lo indicator on the cluster bezel. They don't work. When I had the cluster pulled, the bulbs worked. Is my truck equipped with it or not? BTW, transfer case is manual shifted BW 1356.

Also, I got a bogus code. 133, someone please tell me wtf is this code. Its not listed in my Chilton's manual and fordfuelinjected.com.

Any help is appreciated!
Thanks.

 

I got another code few days ago. 233 is the EDIS problem - Spark Advance Word (SAW) signal error. Where should I start? I wonder if this code is setting off 133, which is not a code by Ford.

 

I'd double check how you're interpreting the blinks. The truck in your signature does not use EDIS. Check this site for a flash diagram: EEC IV Self Test hookup
