P1668?Just got this pending code,any thoughts,solutions?

 

I dont know what that code means and I'm to lazy to Google it for you.

 

1668 is a engine anti-theft circuit high, serial link open to circuit.

 

I too just got this code this morning on my UltraGauge... What does this mean?

 

ihscouts sent this link in - Fault Code P1668

 

So as long as I start the vehicle within 30 seconds of hitting the open button on the remote, I should be ok! Stupid thing! Driving me crazy already... How is it that it just all of a sudden starts throwing this up? I just drove the thing Fri, Sat and Sun and had no codes and no issues. Then this morning I go to start it and I get the 1668!

I did change Spark Plugs to the Platinum +4's, is it possible that I might have hit something or caused this to happen?

 

Did you disconnect the battery while changing the plugs? This error will pop up when the computers come online and cannot talk to each other for a couple of seconds.

 

I did not disconnect the Battery (Really was aware that was required). So is there a way to get this code to reset or go away? I was able to drive all the way to work today without the engine stalling or acting strange. I even stopped at the Gas Station, shut the engine off and then cranked it right up when I got back in.

 

Most likely a control unit made a phone call, and did not get a answer. Check your battery voltage, and check voltage cranking over. May a low voltage. Since it is a pending code comes under three trip code. Clear it and see if it comes back

 

I was wondering about clearing it, but I am very hesitant on doing that. I did go out at lunch and it fired right up and I know it was more than 30 secs after I hit the unlock button on the remote. I will check the voltages when I leave work this afternoon.

Thanks for all the info!
