I got in the truck yesterday morning, started it up and let it warm up for a couple of minutes-- all seemed good-- put it in reverse and it backed about 1 foot and died.

It threw the following codes: P3066- unknown code; P2769-- unknown code; P0602-- checksum error; P0541-- low voltage at air intake heater relay.

Using Smarty I was able to identify the above and reset. I experienced no other trouble since.

Can anyone identify the unknown codes and what does all this mean?

Your help is appreciated.

 

BUMP--

Still need some help please

 

Aw, c'mon...
There's gotta be someone to chime in and help????

 

Can't come up with anything for the 3066, but the 2769 is the TCC control circuit low voltage, and you already have the other 2 codes figured out. I would have to say, check the connections at the batteries and such and go from there. Also look at the a/c wiring coming off of the a/c pressure transducer. Seems to be a common problem area for the 5v reference signal to short out.

 

Thank you! Greatly appreciated...

Anyone else??

 

The 0602 is normal with Smarty. It is a fuel calibration error. If you clear the code and return to the stock program it will not come back. As soon as you go back to any of the Smarty softwares it will be there again.

 

dads 04 thru a bunch of codes at once a couple years back......ended up that a wire was shortign out against the ac compressor or something! so jsut do a quick look over your wiring, see if maybe one has been rubbing on something????

 

Yup, same thing I refereed to ^ !

 

I thought they had an update to fix that?

 

Well I'm running Beta 4.4 sw3 right now..

 

The Smarty has been on for a while now and I have used six or seven different programs including beta 4.4 and 4.3 and there are the first codes I've gotten. I can't say it is or isn't smarty to be truthful-- just don't know enough right now. I can say I've had zero problems with smarty to date and don't want to rush to blame anything.

 

I'll check the A/C wires as indicated above to start
