[oregondiscoII]

hey guys,i had a powertrain code pop up today.its a pending code...P1668.can anyone identify this code for me?thanks a bunch

It's not on any of my code sheets, sorry. Let us know what you find.

This is what i get.

""P1668. Engine anti-theft signal circuit high. Serial link open circuit.""

A quick read has something to do with the ECM and BCM in the "immobilisation system." Have either of yours been replaced? Or have you messed with the alarm system?

[Disco Mike]

Now I remember hearing that one before and I think a good Rover mechanic, not the dealer, is in order for this repair.

yes,the dealer programmed a new remote for my car.its a pending code...will it go away?thanks

Did the code pop up the same day? try and clear it to see if it comes back.
