U1016 SAAB - SCP Invalid or Missing Data for Primary Id
Tech notesThis is typically an electrical wiring connection issue at one of the controllers being monitored by the manufacturer.
It can occur if:
Someone changes a battery while the ignition switch is left on, that is, left in the “Run” position.
Someone flashes/upgrades their engine controller – other modules unable to communicate with the PCM during this process – this will set U1016 at a multitude of controllers on the vehicle – all false codes. Erase and carry on.
When is the code detected?When the PCM is unable to communicate with any other controller on the bus network at any time while the ignition switch is in the “Run” position.
U1016 Saab DescriptionThis is a manufacturer specific fault code and can be used for several different faults, depending upon what the manufacturer wants to use it for. The Powertrain Control Module (PCM) communicates over the Serial Communication Protocol (SCP) bus network, or J1850 bus. This is a medium-speed bus communication system and is fault tolerant, which means any type of intermittent/loose connection at these controllers will cause this code to set in memory, but will still operate, provided a data path is available. When the PCM is unable to communicate with any other controller at any time while the ignition switch is turned on, code U1016 will set. This is the typical reason for this code to set.
