Default CHECK ENG. CODES - P1670,P1671

2 check engine codes were returned - P1670 & P1671. They both read "MANUFACTURER
CONTROLLED COMPUTER AND AUXILIARY OUTPUTS." Is this related to the recent recall
where the computers were reprogrammed for the throttle body issue or is this related
to another issue? Thanks for any input.

Those generic codes are hard to tell since they are generic codes.
The Manufacturer codes. Most of the time you need to have the Volvo codes to see where it leads you.

P1670/71 equate to Volvo code ECM720A whichis a breakdown in the communication to the immobilizer. It could be a faulty engine control module or a faulty immobilizer control moduleat worst or something simple such as a faulty key or bad wiring connection.
