P0560System Voltage
- Generic OBD-II code · Powertrain
- Can trigger limp mode
- How the car detects it
- The module measures its own supply voltage. CARB allows other monitors to be suspended below 11 V, and above a maker's threshold only if the voltage itself is diagnosed – that is what these codes record. GM's engine modules and Ford's PCM set them without warning lamp. P0560 is the general code without low/high split, used differently: Saab's 2002 9-5 transmission module sets it below 9 V or above 18 V for 1 s and goes into limp mode; Saab's EDC16 diesel only above 17 V (24 V charger or jump start); the GM-built 9-4X as a low-voltage code. GM's and Ford's engine modules use P0562/P0563 instead.
